tzhouamandClaude Opus 4.8 7e7b99b60f [CI][Rebase] Fix Ready/Merge pipeline upload by stripping source_file_dependencies
Build #2233 on the vllm-omni-rebase pipeline failed both "Upload Ready
Pipeline" and "Upload Merge Pipeline" with:

  Pipeline upload rejected: `source_file_dependencies` is not a valid
  property on the `command` step.

`source_file_dependencies` is an uploader-only key understood by
upload_pipeline.py, not by Buildkite. #4478 switched the rebase pipeline's
Ready/Merge steps to raw `buildkite-agent pipeline upload` to run the full
e2e suite (bypassing diff-aware skipping), but that also bypassed the
key-stripping, so Buildkite rejected the YAML.

Add a `--all` flag to upload_pipeline.py that forces the keep-all-steps
path (changed_files=None) while still stripping source_file_dependencies,
and use it for the rebase pipeline's Ready/Merge (and Nightly) uploads.
This restores a valid upload AND retains running the full e2e suite on
main builds. Normal-CI .buildkite/pipeline.yml is unchanged (still
diff-aware).

- [ ] **No new `**kwargs` string-lookup plumbing:** the diff adds no `**kwargs` + `kwargs["..."]` / `kwargs.get("...")` / `"..." in kwargs`. ⚠ any new instance; ✗ if a new string key is duplicated across ≥2 files without a shared constant, or unknown keys are silently dropped on a fail-fast path.
- [ ] **No new broad exception swallow:** the diff adds no `except Exception:` / bare `except:`. ⚠ any new instance; ✗ for `except: pass` / `except Exception: return None` / `continue` on a fail-fast path (init, config validation, weight loading, request handling).
- [ ] **No new `Any` / wrong type hints:** the diff adds no `: Any` / `-> Any` / untyped production signature, and no new `SimpleNamespace` in tests faking an object that already has a real typed stub. ⚠ any new instance; ✗ for a *wrong* (actively misleading) annotation or a `SimpleNamespace` test fake of a typed object.
- [ ] **No new hot-path copy:** the diff adds no `.clone()` / `.copy_()` / `copy.deepcopy(...)` inside a per-step loop or per-request path. ⚠ any new instance; ✗ for `.clone()` of a full latent/activations tensor inside an AR or diffusion step loop without a comment, or `deepcopy` of a scheduler / sampling-config on the request path.
- [ ] **No new event-loop blocking:** the diff adds no `time.sleep` / blocking HTTP (`requests`, `urllib`) / `await` inside a held lock in `async def` code. ⚠ any new instance; ✗ for blocking sleep or HTTP on the serving path (`engine/`, `entrypoints/`, async `connectors/`), or a lock held across an `await`. Blocking inside a dedicated worker thread is fine.
Roll the ⚠/✗ counts into the report as a single **Code quality** dimension row.
### Conventions (eyeball — no grep)
Judgment calls that don't grep cleanly — apply them while reading the diff, not as a mechanical check:
- **Right log level** — `info` is for end-user-visible events; routine internal events are `debug`; hot paths are `trace` or removed. Logging is not free.
- **Structured fields over f-strings** — pass dynamic values as structured fields (`logger.info("msg", extra={...})`), not interpolated strings, so they stay greppable and parseable.
- **No reflexive synchronization** — don't add `threading.Lock` / `asyncio.Lock` / `deepcopy` / re-wrap shared state unless there is real concurrent mutation; the GIL covers most Python code. Owners decide their own synchronization — don't pre-lock in a constructor.
- **Context managers for cleanup** — use `with` / `contextlib` for files, locks, CUDA streams, and profilers; not raw `open()` + manual `.close()` or ad-hoc `finally`.
- **No new dependencies without justification** — prefer the stdlib and existing vllm-omni deps; a new top-level dep needs a reason (check `pyproject.toml` / `requirements*.txt`).
- **Naming / interface discipline** — don't rename or change interfaces just for taste in this PR, but do fix names that actively mislead (e.g. `serve` implying a long-running server, `Instance` where multiple instance kinds coexist).

# Code-Quality Patterns
Five fragility patterns to sweep on **every** PR, in both quick and full mode. These are pervasive in the existing codebase (hundreds of pre-existing sites) — so the checks are **diff-scoped**: only lines the PR *adds* count. Whole-repo greps light up every PR with the backlog and are useless.
All commands assume:
```bash
BASE="$(git merge-base HEAD origin/main)"
```
**Severity:** ⚠ for any *new* instance introduced by the diff; ✗ for the acute sub-cases defined per pattern. Acute ✗ findings belong in the report's blocking count.
---
## 1. `**kwargs` string-lookup passthrough
### Anti-pattern
```python
def forward(self, **kwargs):
# BLOCKER-prone: raw dict + string keys duplicated across files
if "runtime_additional_information" in kwargs and \
"model_intermediate_buffer" not in kwargs:
...
```
Real instances of this exact guard are copy-pasted across `cosyvoice3.py`, `indextts2_talker.py` (×2), `indextts2_s2mel_decoder.py`, `qwen3_tts_talker.py`, `qwen3_omni.py`. A typo in any string key silently no-ops; there is no type check, no IDE completion, and unknown keys are silently dropped.
### Why dangerous
Raw `dict` + `**kwargs` + lists of param-name strings is **fragile by construction**: the compiler can't see a missing or misspelled key, so failures are silent. Each duplicated copy is a new place for the strings to drift.
### Severity
- ⚠ any *new* `**kwargs` signature whose body does `kwargs["..."]` / `kwargs.get("...")` / `"..." in kwargs`.
- ✗ when the diff introduces a **new** string key that is duplicated across ≥2 files without a shared module constant, or when `**kwargs` plumbing **silently drops unknown keys** on a fail-fast path (init, config validation, weight loading).
### Detect (diff-scoped)
```bash
git diff ${BASE}...HEAD -- "*.py" | grep "^+[^+]" \
| grep -E '\*\*kwargs|kwargs(\.get|\[)|"[a-z_]+"\s+in\s+kwargs'
```
### Fix
Prefer explicit typed params. The repo already has the right primitive: `msgspec.Struct` with `forbid_unknown_fields=True` rejects unknown keys instead of silently dropping them — see `_StructBase` in `vllm_omni/data_entry_keys.py:105` and `MoriPullRequest` in `vllm_omni/distributed/omni_connectors/connectors/mori_transfer_engine_connector.py:81`. A `@dataclass` or `TypedDict` works too.
If `**kwargs` is unavoidable (vLLM base-class compat), centralize the key strings as module-level constants behind **one** typed accessor, instead of repeating the literal across files.
---
## 2. Broad exception swallow
### Anti-pattern
```python
# BLOCKER-prone: catches everything, returns None on any failure
try:
evt = build_event(...)
return evt
except Exception:
return None
```
Real clusters: `vllm_omni/metrics/stats.py:240,274,367,450` and `vllm_omni/metrics/{modality,utils}.py` — all `except Exception: return None`.
### Why dangerous
A generic `except Exception:` is **too flexible**. If we catch an exception type we don't expect, it is almost always an unhandled edge case that needs to be *fixed* — not swallowed into `None`/`pass`/`continue`. Broad catches turn fixable bugs into silent wrong behavior and make debugging impossible.
The repo backs this with ruff `BLE001` (broad-exception catch); it is currently suppressed via `# noqa: BLE001` in `vllm_omni/patch.py:413`. Prefer fixing over suppressing.
### Severity
- ⚠ any *new* `except Exception:` / `except BaseException:` / bare `except:`.
- ✗ for `except:` / `except Exception: pass|return None|continue` on a **fail-fast path** (init, config validation, weight loading, request handling, connector setup). This extends the Bug-Fix "No silent failure risk" ✗ in [checklists.md](checklists.md).
### Detect (diff-scoped)
```bash
# Any new broad catch (⚠ baseline):
git diff ${BASE}...HEAD -- "*.py" | grep "^+[^+]" \
| grep -E 'except\s*(Exception|BaseException)?\s*:'
# Note: this matches only the immediate-colon swallow forms (`except :`,
# `except Exception:`) — it deliberately excludes specific catches like
# `except ValueError:` and the `except Exception as e:` variant. Eyeball
# the latter; `as e` usually means it is logged, but still verify.
```
### Fix
Catch the **specific** types you actually expect (`ValueError`, `KeyError`, `AttributeError`, `OSError`, `torch.cuda.OutOfMemoryError`, `msgspec.ValidationError`, …). At a genuine top-level / best-effort boundary (metrics, signal handlers), at minimum **log** the exception; never swallow into a bare `pass`/`return None` on a path that should fail loudly.
---
## 3. `Any` / wrong type annotations
### Anti-pattern
```python
# ⚠ Any param + Any return — no contract, no narrowing
def _extract_mm_output(engine_outputs: Any) -> dict[str, Any]:
...
```
### Why dangerous (root cause)
`Any` disables the type checker for that position, so typos and wrong shapes pass silently. The repo has 636 `: Any` params, 244 `-> Any` returns, and **1,173 `SimpleNamespace` in `tests/`**. The `Any` leak is largely test-driven: vibe-coded unit tests fake objects with `SimpleNamespace`, which forces the production code consuming them to be typed `Any`, and the `Any` then propagates outward into public signatures.
### Severity
- ⚠ any *new* `: Any` / `-> Any` / fully-untyped signature in production code.
- ✗ for a **wrong** annotation (actively misleading — e.g. `-> bool` that returns `Optional[bool]`), or a *new* `SimpleNamespace` in a test that mimics an object which already has a real typed stub / `@dataclass` / `TypedDict` / `Protocol`.
### Detect (diff-scoped)
```bash
# Any leaking into new signatures:
git diff ${BASE}...HEAD -- "*.py" | grep "^+[^+]" \
| grep -E ':\s*Any\b|->\s*Any\b'
# SimpleNamespace newly added in tests (the Any-leak source):
git diff ${BASE}...HEAD -- "tests/" | grep "^+[^+]" | grep "SimpleNamespace"
```
### Fix
Replace `Any` with the concrete type, a `Protocol`, or a `Union`. If a type is genuinely dynamic, prefer `object` + `isinstance` narrowing over `Any` — `object` keeps the checker engaged. In tests, replace `SimpleNamespace` with the real class, a small `@dataclass`/`TypedDict`, or a `Protocol` + fake, so the system under test stays fully typed.
---
## 4. Unnecessary copy — `.clone()` / `copy.deepcopy` in hot paths
### Anti-pattern
```python
# Per-step in a diffusion/AR loop: clones the full latent every iteration
for t in timesteps:
trajectory_latents.append(x_t.clone()) # O(N) GPU alloc + memcpy each step
```
Real clusters: `vllm_omni/diffusion/models/bagel/bagel_transformer.py` calls `x_t.clone()` ~9× across a trajectory loop (lines 1820–2186); the cache hooks `vllm_omni/diffusion/cache/teacache/hook.py:155` and `magcache/hook.py:182` clone `hidden_states` per step. Separately, `copy.deepcopy(self.scheduler)` / `copy.deepcopy(req.sampling_params)` is copy-pasted across diffusion pipelines — `pipeline_qwen_image.py:786`, `pipeline_hunyuan_image3.py:1904`, `pipeline_ltx2*.py` (×3), `pipeline_dreamzero.py:1085`, `diffusion_model_runner.py:398` — a full object-graph deepcopy on the request path. (Contrast `dreamzero/causal_wan_model.py:203`, which carries a `# No .clone() needed.` comment — the aware pattern.)
### Why dangerous
A `.clone()` of a GPU tensor or a `copy.deepcopy` of a config object inside a per-step / per-request path is a hidden allocator: it reads as one Python line but triggers a GPU memcpy or a deep object-graph walk every iteration. Across 50 diffusion steps or hundreds of AR steps it dominates latency and VRAM bandwidth. `deepcopy` additionally ignores any custom device / `__copy__` logic and can drag tensors through CPU.
### Severity
- ⚠ any *new* `.clone()` / `.copy_()` / `copy.deepcopy(...)` inside a per-step loop or per-request path.
- ✗ for `.clone()` of a full latent/activations tensor inside an AR or diffusion step loop without an explanatory comment, or `copy.deepcopy` of a scheduler / sampling-config on the request hot path.
### Detect (diff-scoped)
```bash
git diff ${BASE}...HEAD -- "*.py" | grep "^+[^+]" \
| grep -E '\.clone\(\)|\.copy_\(|copy\.deepcopy|deepcopy\('
```
### Fix
Tensors: prefer a view (`x[..., :k]`, `torch.narrow`, `as_strided`) or write into a pre-allocated buffer with `dst.copy_(src)` instead of `.clone()`; if the caller no longer needs the original, `move`/`del` it rather than copy. Schedulers / configs: build a fresh lightweight instance per request, or split out the mutable per-request bits so the shared immutable part isn't deepcopied. If a copy is genuinely required (e.g. the source is mutated in place later), keep it and add a one-line comment saying why.
---
## 5. Blocking the asyncio event loop / lock held across `await`
### Anti-pattern
```python
# BLOCKER-prone: blocking sleep / blocking HTTP / lock held across an await,
# all inside an async (event-loop) function
async def handle(self, req):
with self._lock:
resp = await self._client.call(req) # lock held across await -> serializes all requests
time.sleep(0.1) # stalls the single loop for every concurrent request
```
### Why dangerous
vLLM-Omni serves over a single asyncio event loop. Any synchronous blocking work on an `async def` path — `time.sleep`, blocking HTTP (`requests`/`urllib`), heavy CPU work, or a lock held across an `await` — stalls the loop for *every* concurrent request, not just the blocking one. A lock held across `await` silently serializes the whole pipeline; blocking I/O tanks throughput and inflates tail latency.
### Severity
- ⚠ any *new* `time.sleep(`, blocking HTTP call (`requests.get/post`, `urllib.request`, `urlopen`), or `await` inside a `with Lock` / `async with` critical section, in `async def` code.
- ✗ for `time.sleep` or blocking HTTP on the serving path (`engine/`, `entrypoints/`, async `connectors/`), or a lock acquired and held across an `await` on the request path.
### Detect (diff-scoped)
```bash
# New blocking primitives introduced by the diff — then eyeball whether each
# sits in an async function on the loop vs a dedicated worker thread:
git diff ${BASE}...HEAD -- "*.py" | grep "^+[^+]" \
| grep -E 'time\.sleep|requests\.(get|post|put|delete)|urllib\.request|urlopen'
# Lock acquired with an await potentially inside the critical section (manual eyeball):
git diff ${BASE}...HEAD -- "*.py" | grep "^+[^+]" | grep -E 'async with|\.acquire\(\)'
```
Note: blocking inside a **dedicated worker thread is correct** — the repo already does this (`diffusion/model_loader/hub_prefetch.py`, `distributed/omni_connectors/kv_transfer_manager.py`, the `mooncake`/`mori` connectors poll with `time.sleep` on their own threads). The check targets the *event-loop* path only.
### Fix
Move blocking work off the loop with `asyncio.to_thread(...)` / `run_in_executor`, or use a native async client (`httpx.AsyncClient` / `aiohttp`). Never `await` while holding a lock — drop the lock before the `await` and re-acquire after, or restructure so the critical section contains no `await`.
---
## Running the sweep
Run all five detections against `${BASE}...HEAD`, then for each hit decide ⚠ vs ✗ using the severity rules above. Roll the results into the report as a single **Code quality** dimension row (count of ⚠ and ✗), alongside the type-specific checklist from [checklists.md](checklists.md).

# LVSA Long-Video Showcase
**Training-free block-sparse attention for long-video diffusion**, running on
vLLM-Omni via the public plugin entry points (no core changes). LVSA speeds up
extended-horizon generation and prevents the freeze/loop failure mode dense
attention exhibits beyond a model's training length — with no fine-tuning and no
weight changes.
Upstream: **[LongVideoSparseAttention](https://github.com/JiusiServe/LongVideoSparseAttention)**
(algorithm, all model adapters, full docs).
## Results
Wan 2.1 1.3B, single A100 80 GB, mean over 5 prompts (Dense vs LVSA-FlashInfer):
| Horizon | 1× | 2× | 3× | 4× | 5× | 6× |
|---|---|---|---|---|---|---|
| **Speedup** | 0.9× | 1.4× | 1.9× | 2.5× | 3.0× | **3.5×** |
| **VQeval composite** (Dense→LVSA) | 63→63 | 59→63 | 61→63 | 61→64 | 59→64 | 59→63 |
The speedup **grows with length** (LVSA is the dense regime at 1× by design, so
the win starts at 2×), and quality *improves* at extension — LVSA's rotating
keyframes prevent the looping/static output dense produces beyond its horizon
(VQeval loop-quality +27 to +34 at ≥3×). At long horizons dense **OOMs on 80 GB**
(HunyuanVideo ≥2×, Wan2.1-14B and Cosmos at 6×) where LVSA still generates.
→ Full sweep (5 models × 6 horizons, VQeval + VBench-Long) and the
quality-metric methodology:
**[benchmarks/](https://github.com/JiusiServe/LongVideoSparseAttention/tree/main/benchmarks)**.
## Quickstart
```bash
# 1. vLLM-Omni 0.22.0 (stable) + matching vLLM
pip install "vllm==0.22.0"
pip install --no-build-isolation \
"vllm-omni @ git+https://github.com/vllm-project/vllm-omni.git@v0.22.0"
# 2. LVSA core + plugin
git clone https://github.com/JiusiServe/LongVideoSparseAttention.git
( cd LongVideoSparseAttention && pip install -e . && pip install -e lvsa-vllm-omni/ )
# 3. this showcase's client dep
pip install requests
```
FlashInfer (used by the default `flashinfer` backend) **ships with vLLM** — step 1
already pulls the pinned `flashinfer-python` + `flashinfer-cubin`, so the fused
backend works with no extra install. Two optional extras:
```bash
# (optional) faster startup — prebuilt JIT cache, matched to your CUDA + flashinfer
CU=cu128 # match your CUDA: cu121 / cu124 / cu128 / …
FIVER=$(python -c "import importlib.metadata as m; print(m.version('flashinfer-python'))")
pip install --extra-index-url "https://flashinfer.ai/whl/${CU}" \
"flashinfer-jit-cache==${FIVER}+${CU}"
# (fallback) no FlashInfer in your environment? run the SDPA backend instead:
export LVSA_BACKEND=sdpa
```
```bash
# Serve an LVSA-enabled endpoint (Wan 2.1 1.3B at 2× horizon):
MODEL=/path/to/Wan2.1-T2V-1.3B-Diffusers MODEL_FAMILY=wan FRAMES=161 \
bash serve_lvsa.sh
# In another shell — generate:
python generate.py --frames 161 --height 480 --width 832 \
--prompt "A dog running through a sunlit forest." --out wan_lvsa.mp4
```
`serve_lvsa.sh` sets the LVSA env vars for the chosen `MODEL_FAMILY`
(`wan` / `hunyuan`). Wan and HunyuanVideo run through the LVSA **attention
backend** by default — it stays sparse even under sequence-parallel, unlike the
monkey-patch hooks.
## Configuration
The one knob you must get right is the model's training horizon
(`LVSA_REFERENCE_LATENT_FRAMES`: Wan = 21, HunyuanVideo = 33); `serve_lvsa.sh`
sets it per family. For the full environment-variable reference, the multi-GPU
support matrix, and tuning (`sparsity_scale`, rotating keyframes, non-standard

"""Generate a long video through an LVSA-enabled vLLM-Omni server.
A thin client over the Omni video API — start the server first with
``serve_lvsa.sh``. The sparse attention runs server-side; this just submits a
job and saves the result.
Uses the **asynchronous** endpoint (``POST /v1/videos`` → poll
``GET /v1/videos/{id}`` → download ``GET /v1/videos/{id}/content``) rather than
``POST /v1/videos/sync``. The sync endpoint is capped by a fixed server-side
timeout (``VIDEO_SYNC_TIMEOUT_S``, 600 s) and is documented as
"for benchmark and testing scenarios" — long videos (LVSA's use case) routinely
exceed it. The async job has no such cap.

# Composable parallel strategies
In vLLM-Omni, the `composable_parallel` system layers a declarative *parallel strategy* on top of the existing stage configs. A strategy YAML maps each pipeline stage (by its `model_stage` name) to a stack of axis declarations — one per parallelism dimension — that the engine translates into per-stage parallel sizing (`tensor_parallel_size`, `data_parallel_size`, `pipeline_parallel_size`, expert-parallel toggle, replica count) and, when relevant, an orchestrator-wide load-balancer policy.
Strategies are intentionally narrow: each one only writes the axes it declares, leaving every other engine arg untouched. This makes a strategy file a small, reusable overlay you can swap independently of the deploy YAML (see `configuration/stage_configs.md`).
!!! note
Composable parallel is **opt-in**. Passing `--strategy-config <path/to/strategy.yaml>` overlays the derived sizing onto the registry-merged stages *before* any CLI overrides are applied. When `--strategy-config` is omitted, stages remain exactly as their deploy YAML produces them.
## Top-level schema reference
A strategy file has a single top-level mapping, `strategies`, keyed by the `model_stage` name of each stage you want to overlay. Each value is a list of axis declarations (see [StrategySpec fields](#strategyspec-fields) below).
| Field | Type | Required | Default | Description |
|-------|------|----------|---------|-------------|
| `strategies` | `dict[str, list]` | required | — | Maps `model_stage` name (e.g. `thinker`, `talker`, `code2wav`, `dit`) to a list of axis declarations. The key MUST be the stage name, not the integer `stage_id`. See `vllm_omni/config/composable_parallel/strategy_loader.py`. |
### StrategySpec fields
Each entry in a stage's list becomes one `StrategySpec` (see `vllm_omni/config/composable_parallel/spec.py`). The loader fills in `routing` and `aggregation` from per-kind defaults, so the file stays compact.
| Field | Type | Required | Default | Description |
|-------|------|----------|---------|-------------|
| `axis` | str | required | — | Mesh-axis kind. One of `tp`, `dp`, `pp`, `ep`, `stage_replica` (wired today) or `sp_ulysses`, `sp_ring`, `cfg`, `vae_pp`, `hsdp`, `stage_pp`, `cp` (reserved; declaring one raises `AxisTranslationError` at translate time). See `MeshAxisKind` in `vllm_omni/config/composable_parallel/spec.py`. |
| `size` | int | required | — | Axis degree. Must be `> 0`. |
| `routing` | str | optional | per-kind default | Stateless routing policy. Accepted only for `dp` / `stage_replica`; other kinds reject it. Values: `random`, `round_robin`, `least_queue`. (`hash` is recognised but currently raises `NotImplementedError`.) See `RouteByStage` in `vllm_omni/config/composable_parallel/routing.py`. |
| `l1_owner` | str | optional | per-kind default | Overrides which layer owns request routing for this axis. `engine` for `tp`/`dp`/`pp`/`ep`, `delegated` for `stage_replica`. Recorded into `shard_extension`. |
| `name` | str | optional | axis kind | Human-readable label for this spec, used in error messages. |
Two additional `StrategySpec` slots — `layer_hook_specs` and `kernel_specs` — let advanced authors bind layer-walker hook IDs (`LayerHookSpec`) or kernel IDs (`KernelSpec`) onto an axis. These are not exposed by the YAML loader today and are intended for programmatic construction. See `vllm_omni/config/composable_parallel/spec.py` for the dataclasses.
### CLI flags
| Flag | Description |
|------|-------------|
| `--strategy-config PATH` | Path to a `strategy.yaml`. Only takes effect on registry-based deploy paths (`--deploy-config` or the bundled default deploy YAML). Its derived sizing is overlaid onto the merged stages *before* CLI overrides. |
| `--stage-configs-path PATH` | **Legacy.** Loads the old `stage_args` YAML schema for un-migrated models. Passing `--strategy-config` together with this path is silently inapplicable — vLLM-Omni emits a warning and the strategy is ignored (see `vllm_omni/entrypoints/utils.py`, lines 372–380). |
| `--omni-lb-policy POLICY` | Orchestrator-wide load-balancer policy. Strategy-derived from any `stage_replica` axis; an explicit CLI value wins and must match the derived one or `AsyncOmniEngine` raises `Conflicting load-balancer policy` at construction. |
!!! warning
`--strategy-config` cannot be used with `--stage-configs-path` (the legacy deploy path). If your model has not been migrated to the registry-based pipeline yet, the strategy is silently dropped with a warning. Migrate to a registry-based model or use `--deploy-config` to apply a strategy.
## Sub-schemas
### `axis`
The set of recognised axis kinds is the `MeshAxisKind` enum in `vllm_omni/config/composable_parallel/spec.py`:
```yaml
# Translatable today (see `_SUPPORTED_KINDS` in translator.py).
axis: tp # tensor parallel — sets tensor_parallel_size
axis: dp # engine data parallel — sets data_parallel_size (vLLM's intra-engine DP LB)
axis: pp # pipeline parallel — sets pipeline_parallel_size
axis: ep # dense expert parallel — sets enable_expert_parallel=True; size must equal tp*dp
axis: stage_replica # omni-coordinator-level replica fan-out — sets num_replicas + omni_lb_policy
# Reserved (raise AxisTranslationError today; declared in the type system for forward compat).
axis: sp_ulysses
axis: sp_ring
axis: cfg
axis: vae_pp
axis: hsdp
axis: stage_pp
axis: cp
```
### `routing`
The full closed hierarchy lives in `vllm_omni/config/composable_parallel/routing.py` (`Broadcast`, `PartitionByHash`, `ShardSequence`, `ShardSpatial`, `RouteByExpert`, `PipelineMicrobatch`, `DuplicateWithCondTag`, `RouteByStage`). For YAML authors only `RouteByStage` is exposed as a `routing:` string, and only for `dp` / `stage_replica` axes (other axes have fixed routing — `tp`/`ep` broadcast, `pp` microbatch). Recognised policies:
```yaml
routing: random # uniform-random across replicas/DP ranks
routing: round_robin # cycle through replicas/DP ranks (the default for dp/stage_replica)
routing: least_queue # send to the replica with the smallest backlog
# routing: hash # recognised but raises NotImplementedError; no key-stable balancer yet
```
### `aggregation`
Aggregation is filled in automatically by the loader (`_default_aggregation` in `vllm_omni/config/composable_parallel/strategy_loader.py`) from the axis kind, so users do not author it:
| Axis kind | Aggregation pattern |
|-----------|---------------------|
| `tp`, `ep` | `TakeRank` (all ranks agree; pick one) |
| `dp`, ep (in some flows) | `Union` (disjoint replica results) |
| `pp` | `StitchPipeline` |
| `stage_replica` | `FanInByStage` |
Full pattern hierarchy: `TakeRank`, `Union`, `GatherDim`, `AllGather`, `StitchSpatial`, `StitchPipeline`, `Combine`, `FanInByStage` (see `vllm_omni/config/composable_parallel/aggregation.py`).
## Precedence
From highest to lowest, when the same axis is touched by multiple layers:
1. **CLI overrides** (`--tensor-parallel-size`, `--stage-overrides`, `--omni-lb-policy`, etc.). A CLI value always wins; a warning is emitted whenever it overrides a strategy-declared axis (see `_reconcile_strategy_with_cli` in `vllm_omni/config/config_factory.py`).
2. **Strategy YAML** (`--strategy-config`). Derived sizing is written onto the merged stages with *conflict-on-explicit* semantics — if the deploy YAML already set a value to something different, application raises `StrategyApplyError`.
3. **Deploy YAML** (`--deploy-config` or the bundled `vllm_omni/deploy/<model_type>.yaml`).
4. **Parser defaults.**
After CLI overrides land, the device-layout guard re-runs (`check_device_layout`, called from `_reconcile_strategy_with_cli`) against the *effective* `tp * dp * pp * num_replicas` and the resolved `devices` string, so a `devices` value passed through `--stage-overrides` or a `--tensor-parallel-size` value that conflicts with the strategy's world size cannot slip past the pre-spawn check.
## Worked example
### Example 1 — `strategy_tp2.yaml`
Shard the `thinker` stage with TP=2 on top of the bundled Qwen2.5-Omni deploy YAML. Routing is fixed (broadcast) for TP, so no `routing:` field is needed.
```yaml
# examples/offline_inference/qwen2_5_omni/strategy_tp2.yaml
strategies:
thinker:
- axis: tp
size: 2
```
Launch:
```bash
python3 end2end.py --query-type text --num-prompts 6 \
--strategy-config strategy_tp2.yaml \
--stage-overrides '{"0": {"devices": "0,1"}, "1": {"devices": "2"}, "2": {"devices": "2"}}'
```
Effective `OmniParallelConfig` per stage after the overlay (see `OmniParallelConfig` in `vllm_omni/config/composable_parallel/translator.py`):
| Stage (`model_stage`) | `tensor_parallel_size` | `data_parallel_size` | `pipeline_parallel_size` | `stage_replica_size` | `omni_lb_policy` |
|-----------------------|------------------------|----------------------|--------------------------|----------------------|------------------|
| `thinker` | **2** (from strategy) | 1 | 1 | 1 | — |
| `talker` | 1 | 1 | 1 | 1 | — |
| `code2wav` | 1 | 1 | 1 | 1 | — |
### Example 2 — `strategy_stage_replica.yaml`
Replicate the `thinker` stage across two independent engines and let omni's StagePool round-robin requests across them.
```yaml
# examples/offline_inference/qwen2_5_omni/strategy_stage_replica.yaml
strategies:
thinker:
- axis: stage_replica
size: 2
routing: round_robin
```
Launch:
```bash
python3 end2end.py --query-type text --num-prompts 6 \
--strategy-config strategy_stage_replica.yaml \
--stage-overrides '{"0": {"devices": "0,1"}, "1": {"devices": "2"}, "2": {"devices": "2"}}'
```
Effective per-stage config and the derived orchestrator knob:
| Stage (`model_stage`) | `tensor_parallel_size` | `stage_replica_size` | `omni_lb_policy` (derived) |
|-----------------------|------------------------|----------------------|----------------------------|
| `thinker` | 1 | **2** | **`round-robin`** |
| `talker` | 1 | 1 | — |
| `code2wav` | 1 | 1 | — |
The derived `omni_lb_policy = round-robin` is **not** written into any stage's engine args. Instead it is surfaced on `StrategyApplyResult.omni_lb_policy` and applied once at orchestrator construction by `AsyncOmniEngine._apply_strategy_lb_policy` (see `vllm_omni/engine/async_omni_engine.py`, lines 1107–1134). If you also pass `--omni-lb-policy round-robin` the values must match; passing a different value raises `Conflicting load-balancer policy`.
## Per-field deep-dive
### `name`
Default: the axis kind (e.g. `"tp"`).
Human-readable label that appears in `AxisTranslationError` and `StrategyApplyError` messages. Set it to disambiguate two stages declaring the same axis kind when scanning logs.
### `mesh_axis` (`axis` + `size`)
Default: no default — both fields are required.
`axis` chooses the parallelism dimension; `size` is its degree. Five kinds are wired end-to-end today (`tp`, `dp`, `pp`, `ep`, `stage_replica`); the remaining kinds in `MeshAxisKind` are reserved and raise `AxisTranslationError` at translate time so a typo cannot silently become a no-op (see `_SUPPORTED_KINDS` in `vllm_omni/config/composable_parallel/translator.py`). For `ep`, the size MUST equal `tensor_parallel_size * data_parallel_size`.
### `routing`
Default: per-kind — `RouteByStage(round_robin)` for `dp` and `stage_replica`; `PipelineMicrobatch()` for `pp`; `Broadcast()` for `tp`/`ep` and any other kind.
User-facing string only on `dp` and `stage_replica` axes. The four recognised values are `random`, `round_robin`, `least_queue`, `hash`; `hash` is rejected today with `NotImplementedError`. See `RouteByStage` in `vllm_omni/config/composable_parallel/routing.py`.
### `l1_owner`
Default: per-kind — `engine` for `tp`/`dp`/`pp`/`ep`, `delegated` for `stage_replica`.
Overrides which layer owns request routing along this axis. `engine` means vLLM realizes routing intra-engine; `delegated` means the omni coordinator owns routing across independent replicas. Set this only when overriding the per-kind default in `_DEFAULT_L1_OWNER` (`vllm_omni/config/composable_parallel/translator.py`); invalid values fail fast in `_resolve_l1_owner`.
### `stage_replica` and `omni_lb_policy`
`stage_replica` is *not* a vLLM world dimension; it spins up `size` independent engine replicas of one stage, coordinated by the omni `StagePool` load balancer. The axis writes both:
- The stage's `num_replicas` (a per-stage deploy knob).
- The pipeline-wide `omni_lb_policy` string (an orchestrator-level knob).
Because `omni_lb_policy` is read once at `AsyncOmniEngine` construction — not from per-stage engine args — only one value is allowed across the whole pipeline. If two stages declare conflicting policies, application raises (see `apply_strategy_specs` in `vllm_omni/config/composable_parallel/apply.py`, lines 253–260). To set this knob manually instead, use `--omni-lb-policy` on the CLI; see [the model stage docs](stage_configs.md) for how stage replicas plug into the orchestrator at runtime.
### `model_stage` keys
Default: no default — required for every entry under `strategies:`.
Strategy keys MUST be `model_stage` *names* (strings), the same labels stage configs use for `engine_args.model_stage` (see [`model_stage` in `stage_configs.md`](stage_configs.md#engine_argsmodel_stage)). Integer `stage_id` values are not accepted; the resolver matches on `model_stage` exactly (`_resolve_stage` in `vllm_omni/config/composable_parallel/apply.py`).
## Common pitfalls
!!! warning "Using `stage_id` integers as keys"
Strategy keys are `model_stage` names (str), not integer stage IDs. A file that uses an integer index will raise at apply time:
```text
StrategyApplyError: strategy role model_stage=0 did not match any stage;
available stages: 'thinker'(id=0), 'talker'(id=1), 'code2wav'(id=2)
```
Use the `model_stage` name (e.g. `thinker`) instead.
!!! warning "Mixing CLI overrides with a strategy on the same axis"
A strategy is meant to be the single writer for the axes it declares. If a CLI override (`--tensor-parallel-size 2`, `--stage-overrides '{"0": {"tensor_parallel_size": 2}}'`) sets the same axis, the **CLI value wins** and a warning is emitted from `_reconcile_strategy_with_cli`. The device-layout guard then re-runs against the effective layout, so a CLI override that breaks `tp * dp * pp * num_replicas` will still fail fast at config time.
!!! warning "Passing `--strategy-config` against the legacy `--stage-configs-path`"
Composable parallel only applies on the registry-based deploy path. If a model still resolves through the legacy `stage_args` YAML (loaded via `--stage-configs-path`), `--strategy-config` is silently inapplicable and emits:
```text
--strategy-config (<path>) was provided but model '<model>' resolves via the
legacy stage_configs YAML path, which does not support composable-parallel
strategies; the strategy is ignored. Use a registry-based model to apply it.
```
Migrate the model to the new deploy schema (see `configuration/stage_configs.md`) before applying a strategy.
!!! warning "Conflicting `omni_lb_policy` across stages"
`omni_lb_policy` is a single pipeline-wide knob. If two `stage_replica` axes in different stages derive different policies, `apply_strategy_specs` raises:
```text
StrategyApplyError: role 'talker' derives omni_lb_policy='least-queue-length'
but role 'thinker' already derived 'round-robin'. The load-balancer policy is
pipeline-wide; only one value is allowed.
```
Make the policies match, drop one, or supply the value explicitly via `--omni-lb-policy`.

# Deploy and legacy stage configurations
# Stage configs for vLLM-Omni
In vLLM-Omni, a model's `PipelineConfig` defines its fixed stage topology, while a deploy configuration controls how those stages run. Models that have not migrated to this split still use legacy stage configurations with a `stage_args` schema.
In vLLM-Omni, the target model is separated into multiple stages, which are processed by different LLMEngines, DiffusionEngines or other types of engines. Depending on different types of stages, such as Autoregressive (AR) stage or Diffusion transformer (DiT) stage, each can choose corresponding schedulers, model workers to load with the Engines in a plug-in fashion.
!!! note
Default deploy config YAMLs (for example, `vllm_omni/deploy/qwen2_5_omni.yaml`, `vllm_omni/deploy/qwen3_omni_moe.yaml`, and `vllm_omni/deploy/qwen3_tts.yaml`) are bundled and loaded automatically when neither `--stage-configs-path` nor `--deploy-config` is provided — the model registry resolves the right pipeline + deploy YAML by `model_type`. The bundled defaults have been verified on 1xH100 for Qwen2.5-Omni and 2xH100 for Qwen3-Omni. Models that have not yet migrated to the new schema continue to use the legacy `vllm_omni/model_executor/stage_configs/<model>.yaml` files via `--stage-configs-path`.
## Deploy configuration schema

The new deploy schema lives under `vllm_omni/deploy/` and is paired with a frozen `PipelineConfig` registered by the model's `pipeline.py`. Each deploy YAML has these top-level fields:

## Legacy stage configuration reference
The remainder of this page documents the deprecated `stage_args` schema for models that have not migrated to deploy configurations. The following historical Qwen2.5-Omni configuration illustrates that schema; current Qwen2.5-Omni deployments should use `vllm_omni/deploy/qwen2_5_omni.yaml` instead.

## Naming Model Examples
Offline inference and online serving examples for the same model use the same
directory name and the shared display name in
`examples/model_display_names.yml`. Use these title forms:
- `# <Model>: Offline inference`
- `# <Model>: Online serving`
The documentation generator uses the full title for the page H1 and the shared
display name alone for navigation, and fails the build if a mapped README uses
a different H1. Keep checkpoint identifiers in commands and prose rather than
in the display name, and do not rename an existing example directory solely to
adjust its title because the directory defines its public documentation URL.

#### Parametrization and markers
- Each test module defines a **`RELIABILITY_SCENARIOS`** list (`test_name`, `server_params`: model, `stage_config_name` or diffusion `server_args`, etc.). **`create_reliability_omni_server_params()`** in `tests/dfx/conftest.py` resolves stage paths (including XPU substitutions where applicable) and builds **`OmniServerParams`** lists consumed by **`@pytest.mark.parametrize(..., indirect=True)`** on `omni_server` or `omni_server_function`.
- Cases are tagged **`@pytest.mark.slow`** for weekly / selective CI. GPU-heavy suites use **`@hardware_test(res={"cuda": "H100"}, num_cards=...)`** or **`@hardware_test(res={"cuda": "L4"}, num_cards=1)`** (Qwen3-Omni **2**× H100; Wan2.2 **1**× H100; HunyuanImage DiT **4**× H100; VoxCPM2 **1**× L4).
- Cases are tagged **`@pytest.mark.slow`** for weekly / selective CI. GPU-heavy suites use **`@hardware_test(res={"cuda": "H100"}, num_cards=...)`** (Qwen3-Omni paths often require **2** cards; Wan2.2 video paths **1** card).
- **Process-kill** tests use **`@pytest.mark.skipif(os.name == "nt", ...)`** because injection uses POSIX **`pgrep` / `kill`**.
#### CI trigger
Weekly Buildkite (`.buildkite/test-weekly.yml`) runs one step per model suite (trigger: `WEEKLY=1` or PR label `weekly-test`), for example:

Our test scripts use the pytest framework. First, please use `git clone https://github.com/vllm-project/vllm-omni.git` to download the vllm-omni source code. Then, in the root directory of vllm-omni, you can run the following commands in your local test environment to execute the corresponding test cases.
### CI job runners (L2–L4): logs, timing, and timeouts
[`tools/run_ready_jobs.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/run_ready_jobs.sh), [`tools/run_merge_jobs.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/run_merge_jobs.sh), and [`tools/nightly/run_nightly_jobs.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/nightly/run_nightly_jobs.sh) share the same run-time behavior (via [`tools/run_jobs_common.sh`](https://github.com/vllm-project/vllm-omni/blob/main/tools/run_jobs_common.sh)):
**Log layout** (default under `logs/ready_jobs`, `logs/merge_jobs`, or `logs/nightly_jobs`; override with `--log-dir`):
| Path | Description |
|------|-------------|
| `jobs/*.sh` | Generated per-step bash wrappers |
| `jobs/.job_timeouts` | Job key → `timeout_in_minutes` from Buildkite YAML (when set) |
| `<job_key>.log` | Tee output for each job |
| `timing_summary.log` | Per-job duration and total wall time after the run completes |
**Timing:** while each job runs, stderr prints `finished in …` or `failed after …`. When all jobs finish, a summary is printed and written to `timing_summary.log`, for example:
```
=== Job timing summary ===
TTS_VoxCPM2_Test 25m 40s OK
Omni_Qwen3-Omni_Test 8m 05s TIMED OUT
Total wall time: 33m 45s (2 jobs)
Failed jobs: 1/2
```
**Timeouts:** if a Buildkite step defines `timeout_in_minutes`, the runner wraps that job with `timeout ${N}m` (aligned with CI). Steps without `timeout_in_minutes` rely on any inline `timeout …` already present in the extracted pytest command. On timeout the process exits with code `124` and the summary marks the job as `TIMED OUT`.

## 7. Orchestrator Monitor
> **Warning:** Diagnostic only. Adds lightweight counters on the orchestrator poll loop and per-replica queue depth. Disable in production unless you are actively debugging orchestrator saturation.
Multi-stage omni pipelines route client-facing outputs and inter-stage connector traffic through a single-process orchestrator. When that loop is saturated (for example by large multimodal payloads on the poll path), TTFT and stability can degrade even when GPU stages are healthy. The orchestrator monitor records time-series signals to confirm whether the orchestrator or downstream stage queues are the bottleneck.
Enable on the stage-0 (orchestrator) process:
```bash
vllm serve Qwen/Qwen3-Omni-30B-A3B-Instruct --omni --port 8091 \
--stage-id 0 \
--enable-orch-monitor
```
Optional output path override:
```bash
export VLLM_OMNI_ORCH_MONITOR_PATH=/tmp/vllm_omni_orch_monitor.json
```
If unset, the monitor writes `./vllm_omni_orch_monitor_<MMDDHHMM>.json` at shutdown.
### Recorded metrics
Each 1-second window records:
| Series | Description |
|---|---|
| `windows.duration_s` | Wall time covered by the window |
| `windows.loop_idle` / `windows.loop_active` | Orchestrator poll-loop iterations with no work vs. active forwarding |
| `replicas.<stage,replica>.outputs_queue_size` | MP client `outputs_queue` backlog for that replica |
| `replicas.<stage,replica>.inflight` | Requests currently bound/routed to the replica |
On shutdown the server also logs a short summary (`loop_active_pct`, per-replica queue averages/maxima).
### Relationship to other diagnostics
This monitor is intentionally separate from the existing profiling tools:
| Tool | Scope | Output |
|---|---|---|
| `--enable-diffusion-pipeline-profiler` | Diffusion stage functions (`vae.decode`, `diffuse`, …) | Per-request `stage_durations` / logs |
| `--enable-ar-profiler` | AR stage generation time | Per-request `stage_durations` |
| `profiler_config` (`torch` / `cuda`) | GPU/CPU kernels inside a stage worker | `trace.json`, Nsight, operator tables |
| Prometheus `/metrics` (`vllm:omni_*`) | Pipeline SLOs and cross-stage transfer | Continuous scrape endpoint |
| `--enable-orch-monitor` | Orchestrator poll loop + replica queue backlog | Single JSON file at shutdown |
The orchestrator monitor does not use `torch.profiler` because the bottleneck signal lives in the orchestrator process (poll-loop duty cycle and queue depth), not inside stage workers. It complements Prometheus metrics when you need a post-run time series for a benchmark or regression run.
Process liveness monitors (`monitor_engine_liveness`, worker/engine-core monitors) are unrelated: they detect crashed workers, not orchestrator load.

The primary goal of the vLLM-Omni project is to build the fastest and easiest-to-use open-source Omni-Modality model inference & serving engine. vLLM-Omni extends the original vLLM, which was created to support large language models for text-based autoregressive (AR) generation tasks. vLLM-Omni is designed to support:
* **Non-textual Output:** Enables the integration, efficient processing and output of various data types, including but not limited to, images, audio, video, and action trajectories, alongside text.
* **Non-textual Output:** Enables the integration, efficient processing and output of various data types, including but not limited to, images, audio, and video, alongside text.
* **Non-Autoregressive Structure:** Support model structure beyond autoregressive, especially Diffusion Transformer (DiT), which is widely used in visual and audio generation.
* **Integration with vLLM Core:** Maintain compatibility and leverage existing vLLM key modules and optimizations where applicable.
* **Extensibility:** Design a modular and flexible architecture that can easily accommodate new modalities, model architectures, and output formats.

# Request-Level Batching for Diffusion
This document describes the request-mode batching path for diffusion pipelines.
For end-user enablement and tuning, see
[Request-Level Batching](../../user_guide/diffusion/request_batching.md).
This is separate from
[Continuous Batching for Step-Wise Diffusion](diffusion_continuous_batching.md).
Request-level batching runs one full pipeline `forward()` over a static batch of
compatible requests. Step-wise continuous batching admits work between denoise
steps when `step_execution=True`.
## Why It Helps
The request-level design avoids coupling several logical requests to one request
object. This keeps request identity, abort/error handling, and per-request
metadata unambiguous while still allowing one fused pipeline forward pass for
bursty or concurrent traffic.
## Overview
With request-level batching enabled:
- each `OmniDiffusionRequest` contains one `prompt` and one `request_id`
- the scheduler groups compatible waiting requests into one scheduler wave
- `DiffusionRequestBatch` wraps the scheduled requests for pipeline `forward()`
- batch-capable pipelines return `list[DiffusionOutput]`, one output per
request
- `BatchRunnerOutput` maps each result back to its original `request_id`
Pipelines opt in with `supports_request_batch = True` and a `forward()` method
that accepts `DiffusionRequestBatch` and returns `list[DiffusionOutput]`.
Pipelines that do not opt in keep the existing per-request execution path.
## Enablement
Request-level batching is the request-mode path, so `step_execution` must remain
disabled. Increase `max_num_seqs` above `1` to let the scheduler keep multiple
compatible requests active:
```bash
vllm serve Qwen/Qwen-Image --omni \
--port 8091 \
--max-num-seqs 4
```
For bursty online ingress, `request_batch_max_wait_ms` can add a bounded
admission wait before the first `schedule()` of a scheduler wave:
```bash
vllm serve Qwen/Qwen-Image --omni \
--port 8091 \
--max-num-seqs 4 \
--request-batch-max-wait-ms 20
```
`request_batch_max_wait_ms=0` disables this wait and is the default.
## Request Contract
`OmniDiffusionRequest` represents one logical request. It owns one prompt,
sampling parameters, request id, and request-local metadata. Runtime batches are
formed by the scheduler and represented separately from the request payload.
Runtime batching is represented by:
- [`DiffusionSchedulerOutput`](gh-file:vllm_omni/diffusion/sched/interface.py)
for scheduled request ids and request payloads
- [`DiffusionRequestBatch`](gh-file:vllm_omni/diffusion/worker/request_batch.py)
for the pipeline-facing request batch
- [`BatchRunnerOutput`](gh-file:vllm_omni/diffusion/worker/utils.py) for
per-request results
`DiffusionRequestBatch` intentionally exposes compatibility properties such as
`prompts`, `sampling_params`, `request_id`, and `kv_sender_info` so migrated
pipelines can stay close to upstream code while using a batch-aware contract.
## Scheduler
The scheduler derives its capacity from `max_num_seqs` through
`max_num_running_reqs`. It exposes waiting/running queue counters so the engine
can decide whether admission wait is useful before scheduling a new wave.
Batch compatibility is controlled by
[`SamplingParamsKey`](gh-file:vllm_omni/diffusion/sched/interface.py). The key
contains shape-sensitive and guidance-sensitive fields, including output count
and LoRA identity. Requests with incompatible shapes, CFG settings, output
counts, LoRA adapters, or LoRA scales are kept in separate batches.
Admission is conservative:
- the scheduler only batches compatible requests
- FIFO ordering is preserved
- an incompatible request at the head of the waiting queue blocks later
compatible requests
## Engine
[`DiffusionEngine`](gh-file:vllm_omni/diffusion/diffusion_engine.py) resolves
request-batch capability during initialization from the configured pipeline
class, including custom pipeline classes.
The capability check uses the pipeline class attribute
`supports_request_batch = True`. Pipelines that set this attribute must implement
a request-batch-compatible `forward()` contract and return one
`DiffusionOutput` per request; the runner validates that return shape at runtime.
When the selected pipeline is batch-capable and `step_execution=False`, request
mode routes scheduler waves through the batch executor path. Otherwise it keeps
the per-request executor path.
The optional admission wait runs only when:
- request batching is supported
- `step_execution=False`
- `request_batch_max_wait_ms > 0`
- no requests are currently running
The wait exits early when the waiting queue reaches capacity, when the queue is
stable for a short window, when the deadline expires, or when the engine stops.
## Executor And Runner
The executor exposes two request-mode entries:
- `execute_request`: one worker call per scheduled request
- `execute_batch`: one worker call for the whole `DiffusionSchedulerOutput`
On the batch path, the worker builds a `DiffusionRequestBatch` and runs the
pipeline once. Request-local setup remains per request:
- KV transfer metadata
- random generator and seed handling
- request output/error/abort mapping
Shared batch setup happens once per batch when possible:
- cache refresh
- LoRA activation for the homogeneous adapter key
- pipeline `forward(req_batch)`
Large tensor IPC still uses the shared-memory packing path. The packer traverses
both normal `RunnerOutput.result` wrappers and nested batch results so batched
outputs do not fall back to pickle IPC for tensor payloads.
## Current Limitations
- Only pipelines that declare the request-batch contract use fused batch
execution.
- Batches are homogeneous under `SamplingParamsKey`; heterogeneous resolution or
incompatible guidance settings do not co-batch yet.
- FIFO scheduling can reduce batching opportunities when an incompatible
request is at the front of the queue.
- `request_batch_max_wait_ms` improves burst coalescing but can add latency to
the first request in a scheduler wave. Keep it small for latency-sensitive
serving.
- Step-wise continuous batching is documented separately and only applies when
`step_execution=True`.

## Spatially-Sharded Decode (Wan)
The tile-parallel executor above assigns independent spatial **tiles** to ranks. The Wan VAE additionally supports a **spatially-sharded decode** backend, selected through `DiffusionParallelConfig.vae_parallel_mode` (`"spatial_shard_height"` or `"spatial_shard_width"`; default is `"tile"`).
### How it differs from tile parallel
| Aspect | Tile parallel (`"tile"`) | Spatially-sharded (`"spatial_shard_height"`/`"spatial_shard_width"`) |
|--------|--------------------------|-----------------------------------------------|
| Unit of work | Independent overlapping tiles | A single global feature map sharded along H or W |
| Cross-rank communication | Gather tiles to rank 0, stitch + blend | Per-conv **halo exchange** of boundary rows/cols (P2P) |
| Output assembly | Blend overlapping tiles | All-gather shards on rank 0, trim padding (matches `broadcast_result=False`) |
| Scope | Decode + encode | Decode only |
Spatial-shard decode swaps the decoder's spatial convolutions/padding for halo-exchanging variants (`WanDistConv2d`, `WanDistCausalConv3d`, `WanDistZeroPad2d`) so each rank only holds a shard of the activations but still sees the correct receptive field at shard boundaries. Implementation lives in `vllm_omni/diffusion/distributed/autoencoders/wan_spatial_shard.py`.
### Wiring
`vae_parallel_mode` flows through the same path as `vae_patch_parallel_size`:
```text
serve.py (--vae-parallel-mode) / OmniEngineArgs
-> DiffusionParallelConfig.vae_parallel_mode
-> registry.py: model.vae.set_parallel_size(vae_pp_size, mode=...)
-> DistributedVaeExecutor.parallel_mode
-> DistributedAutoencoderKLWan.tiled_decode dispatch
```
`DistributedAutoencoderKLWan._spatial_shard_decode_enabled()` gates the path: it requires distributed decode to be enabled, a 5D latent, and `vae_patch_parallel_size == DiT group size`. Otherwise it logs a warning and falls back to tile-parallel decode.
### Notes
- The decoder is patched **in place** the first time spatial-shard decode runs and is bound to a single split dimension for the lifetime of the VAE instance.
- Numerical correctness vs. single-GPU decode is covered by `tests/diffusion/distributed/test_wan_spatial_shard.py::test_spatial_shard_decode_matches_reference` (multi-GPU, nightly `full_model` + `distributed_cuda`).

# SAGE + Skip-Softmax — API Design & Test Plan
**Target: merge by 2026-07-24 for the v0.26.0 release.**
## Part 1 — API Design
*How the user uses the trtllm-gen backend.*
### 1. trtllm-gen backend = BF16 dense (baseline)
```bash
vllm-omni serve <model> --diffusion-attention-backend trtllm-gen
# env equivalent:
export DIFFUSION_ATTENTION_BACKEND=trtllm-gen
```
= BF16 dense baseline. SAGE / Skip opt-in on top.
### 2. Add FP8-SAGE
```bash
vllm-omni serve <model> --diffusion-attention-backend trtllm-gen --trtllm-gen-sage
# env: TRTLLM_GEN_SAGE=1
```
FP8-SAGE (no calibration).
### 3. Add Skip-Softmax (needs a calibrated checkpoint)
```bash
vllm-omni serve <model> \
--diffusion-attention-backend trtllm-gen --trtllm-gen-sage \
--trtllm-gen-target-sparsity 0.5 \ # skip amount; omit = no skip
--trtllm-gen-disabled-until-timestep 0.6 # keep initial (noisy) denoise steps dense
```
Needs a ModelOpt-calibrated checkpoint. No calibrated checkpoint → skip stays off (dense).
### 4. vLLM-Omni knobs
```python
@dataclass
class TrtllmGenConfig: # mirrors TRT-LLM SkipSoftmaxAttentionConfig, DiT-flavored
sage: bool = False # FP8-SAGE
target_sparsity: float | None = None # None -> no skip; needs calibrated checkpoint
disabled_until_timestep: float = 0.0 # keep initial (noisy) steps dense; per-model preset

| `--trtllm-gen-disabled-until-timestep <float>` | preset | keep initial steps dense (t 1→0) |

If you are seeing strange behavior with the `vllm` command not handling the `--omni` flag correctly, you most likely have a version mismatch with vLLM < `0.25.0` and vLLM Omni `0.25.0`, as vLLM Omni no longer hijacks the vLLM entrypoint. Updating vLLM should resolve this issue.

For diffusion pipelines, each prompt becomes a separate logical request.
The runtime may automatically batch compatible in-flight requests through
the scheduler and runner.
However, it is not currently recommended to do so
because not all models support batch inference,

This feature is primarily for the sake of interface compatibility with vLLM and to allow for future improvements.

For diffusion pipelines, the stage config field `stage_args.[].engine_args.max_num_seqs` is 1 by default, and the input
list is sliced into single-item requests before feeding into the diffusion pipeline. For models that do internally support
batched inputs, you can [modify this configuration](../configuration/stage_configs.md) to let the model accept a longer batch of prompts.

The response shape depends on the streaming parameters:
**Non-streaming (default).** With `stream=false` and no `stream_format`, returns the
complete clip as binary audio data with an appropriate `Content-Type` header (e.g.
`audio/wav`). The raw-bytes body has no JSON carrier, so no `usage` is reported.

WAV) as they are decoded.

## HuggingFace Kernels Hub Backends
To achieve perfect numerical consistency between **training** (typically using HuggingFace Diffusers with Hub kernels) and **serving/rollout** (using vLLM-Omni), you can use the Hub-based attention backends. This eliminates numerical drift / sampling divergence caused by executing different local kernel versions during rollout.
The following backend options are supported:
- `FLASH_ATTN_HUB` (HuggingFace `kernels-community/flash-attn2`)
- `FLASH_ATTN_3_HUB` (HuggingFace `kernels-community/flash-attn3`, Hopper sm_90+ only)
### Installation
To use these backends, you must install the `kernels` library:
```bash
pip install kernels==0.14.1
```
If the `kernels` library is not available in the environment, vLLM-Omni will log a warning and fall back gracefully to the corresponding local backend implementations (`FLASH_ATTN`). On CUDA GPUs below Hopper (compute capability < 9.0), `FLASH_ATTN_3_HUB` falls back to `FLASH_ATTN_HUB`.

```bash

### Component offloading for split models (e.g. Cosmos3)
Some models split their transformer into mutually-exclusive *components* that run
in different phases of a single forward pass rather than as separate pipeline
components -- e.g. Cosmos3's understanding (reasoner) component runs once per
generation while the generation (generator) component runs every denoising step.
Such models have no separate text encoder to swap against, so the transformer
owns a small model-local offload path and wraps each phase with
`with self._offload_context(name):`
```python
class Cosmos3VFMTransformer(nn.Module):
def forward(self, ...):
with self._offload_context("reasoner"):
... # understanding pass, runs once
with self._offload_context("generator"):
... # denoising pass, runs every step
```
Model-level offloading then keeps exactly one component GPU-resident at a time
(the other on CPU), reusing the same `SequentialOffloadHook` `.to()` movers. The
pipeline opts in by exposing `enable_omni_model_cpu_offload` (which drives the
transformer's `enable_model_cpu_offload` and pins the VAE). Layerwise offloading
works for these models too -- each component declares its own block container via
`_layerwise_offload_blocks_attrs`.

## Spatially-Sharded Decode (Wan)
The default `vae_parallel_mode="tile"` distributes whole tiles across ranks. For the **Wan** VAE there is an alternative decode strategy, **spatially-sharded decode**, selected via `vae_parallel_mode="spatial_shard_height"` or `vae_parallel_mode="spatial_shard_width"`.
Instead of assigning independent tiles to ranks, spatial-shard decode shards the decoder feature maps along the height (`spatial_shard_height`) or width (`spatial_shard_width`) dimension and exchanges halo rows/columns between neighboring ranks around the spatial convolutions. This keeps the receptive field correct across shard boundaries, so the result matches the single-GPU decode within numerical tolerance.
```python
from vllm_omni import Omni
from vllm_omni.diffusion.data import DiffusionParallelConfig
omni = Omni(
model="Wan-AI/Wan2.1-T2V-1.3B-Diffusers",
parallel_config=DiffusionParallelConfig(
tensor_parallel_size=2,
vae_patch_parallel_size=2, # must match the DiT group size
vae_parallel_mode="spatial_shard_width", # or "spatial_shard_height"
),
)
```
Or from the CLI / serving entrypoint:
```bash
vllm serve Wan-AI/Wan2.1-T2V-1.3B-Diffusers --omni \
--tensor-parallel-size 2 \
--vae-patch-parallel-size 2 \
--vae-parallel-mode spatial_shard_width
```
**Constraints and behavior:**
- Spatial-shard decode is **decode-only** and currently implemented for the **Wan** VAE. Other models ignore `spatial_shard_*` modes.
- It requires `vae_patch_parallel_size` to **match the DiT process group size**. If it does not, the VAE logs a warning and **falls back to tile-parallel decode** at runtime.
- `spatial_shard_height` and `spatial_shard_width` are mutually exclusive for a given VAE instance (the decoder is patched in place for a single split dimension).
For end-to-end latency/throughput, launch serving with the desired `vae_parallel_mode` and use the existing diffusion serving benchmark:
```bash
python3 benchmarks/diffusion/diffusion_benchmark_serving.py \
--endpoint /v1/videos --dataset random --task t2v --num-prompts 1 \
--height 480 --width 832 --num-frames 17 --max-concurrency 1

@@ -1,110 +0,0 @@
# Request-Level Batching
Request-level batching lets diffusion serving combine multiple compatible
logical requests into one pipeline `forward()` call. Each prompt remains a
separate request with its own `request_id`, sampling parameters, seed, output,
error, and abort state. The scheduler decides which requests can run together.
!!! warning "Prompt List Semantics"
Diffusion request-level batching does not support a top-level packed
list-prompt request. Submit multiple prompts as independent requests and let
the scheduler batch compatible in-flight requests. Multimodal payloads stay
inside a single prompt dict, for example
`{"prompt": "...", "multi_modal_data": {"image": image}}`.
## Enablement
Increase `max_num_seqs` above `1` to allow the request scheduler to keep more
than one compatible request active:
```bash
vllm serve Qwen/Qwen-Image --omni \
--port 8091 \
--max-num-seqs 4
```
For bursty online traffic, you can also set a small admission wait window. This
lets the engine wait briefly before the first `schedule()` of a new wave so
nearby compatible requests can arrive and share the same fused forward pass:
```bash
vllm serve Qwen/Qwen-Image --omni \
--port 8091 \
--max-num-seqs 4 \
--request-batch-max-wait-ms 20
```
`--request-batch-max-wait-ms 0` is the default and disables admission waiting,
so there is no added wait latency.
For deploy YAMLs, configure the diffusion stage engine args:
```yaml
stage_args:
- stage_id: 0
stage_type: diffusion
engine_args:
max_num_seqs: 4
request_batch_max_wait_ms: 20
```
## Compatibility
Only pipelines that declare request-batch support use the fused request-batch
path. The engine validates that the pipeline `forward()` uses the request-batch
contract and returns `list[DiffusionOutput]`. Pipelines that do not support this
contract do not use fused `pipeline.forward(batch)`; scheduled requests are
executed through per-request worker calls.
The scheduler batches only compatible requests. Compatibility is based on
shape-sensitive and guidance-sensitive sampling fields, including resolution,
frame count, CFG settings, output count, and LoRA identity. Requests with
different LoRA adapters or scales are kept in separate batches so the worker
activates one adapter per batch.
Request-level batching applies when `step_execution=False`. For the separate
step-wise runtime, see [Step Execution](step_execution.md).
## Tuning
- `max_num_seqs` caps the number of active compatible requests in one scheduler
wave.
- `request_batch_max_wait_ms` is an upper bound on extra admission wait before a
new wave starts. Keep it small for latency-sensitive serving; values such as
`10` to `50` ms are a practical starting range for bursty HTTP ingress.
- `0` disables admission waiting and preserves the lowest first-request latency.
- FIFO ordering is conservative: an incompatible request at the front of the
waiting queue can block later compatible requests from joining the current
batch.
## Python API
When constructing `Omni`, pass the same engine arguments:
```python
from vllm_omni.entrypoints.omni import Omni
omni = Omni(
model="Qwen/Qwen-Image",
max_num_seqs=4,
request_batch_max_wait_ms=20.0,
)
outputs = omni.generate(
[
"a cup of coffee on a table",
"a toy dinosaur on a sandy beach",
"a fox waking up in bed and yawning",
]
)
```
`Omni.generate([...])` submits each list item as its own logical diffusion
request. The runtime may batch those requests internally when their sampling
parameters are compatible.

When a parameter is available in the vLLM-Omni interface, it will be adapted here.
But if that parameter is simultaneously set in both the vLLM-Omni interface and `diffusers_call_kwargs`, the **former** will take precedence (because it is set at request time).
### Quantization
Use `diffusers_load_kwargs` for Diffusers-native quantization options. If
`diffusers_load_kwargs["quantization_config"]` is provided as a dictionary, the
diffusers backend builds a Diffusers quantization config and lets Diffusers
validate it before calling `DiffusionPipeline.from_pretrained()`.
The diffusers backend also provides a small compatibility shortcut for
vLLM-Omni quantization configs when `diffusers_load_kwargs` does not already
contain `quantization_config`. Currently this maps online/dynamic `fp8` and
online/dynamic `int8` to Diffusers/TorchAO dynamic quantization for transformer
components such as `transformer` or `transformer_2`. This path requires
`torchao` to be installed.
For example, the CLI can request dynamic FP8 through the vLLM-Omni interface:
```bash
vllm serve "Qwen/Qwen-Image" \
--omni \
--diffusion-load-format diffusers \
--quantization-config '{"method": "fp8"}'
```
Other vLLM-Omni quantization methods, such as `gguf`, `modelopt`, `mxfp4`,
`mxfp8`, serialized checkpoints, static FP8 configs, and layer-name skip lists
such as `ignored_layers`, are intentionally not translated by this compatibility
shortcut. Use Diffusers-native configuration through `diffusers_load_kwargs` or
a native vLLM-Omni pipeline for those cases.

# BitsAndBytes W4 Quantization
## Overview
BitsAndBytes 4-bit quantization supports weight-only NF4/FP4 diffusion transformer
inference on CUDA GPUs. It quantizes BF16/FP16 weights at load time; activations
stay in BF16/FP16. No pre-quantized checkpoint is required.
This is an online (dynamic) path: load the normal HuggingFace checkpoint and
quantize during model loading via the `bitsandbytes` CUDA kernels.
## Hardware Support
| Device | Support |
|--------|---------|
| NVIDIA CUDA GPU (SM 75+) | ✅ |
| NVIDIA Blackwell GPU (SM 100+) | ✅ |
| NVIDIA Ada/Hopper GPU (SM 89+) | ✅ |
| NVIDIA Ampere GPU (SM 80+) | ✅ |
| AMD ROCm | ❌ |
| Intel XPU | ❌ |
| Ascend NPU | ❌ |
Legend: `✅` supported, `❌` unsupported. Non-CUDA platforms raise in
`get_quant_method()`; CUDA requires compute capability 7.5+ (`SM 75+`).
Requires the optional `bitsandbytes` package (`pip install bitsandbytes`).

## Configuration
Python API:
```python
from vllm_omni import Omni
from vllm_omni.inputs.data import OmniDiffusionSamplingParams
omni = Omni(model="Tongyi-MAI/Z-Image-Turbo", quantization="bitsandbytes")
omni_with_skips = Omni(
model="Tongyi-MAI/Z-Image-Turbo",
quantization_config={
"method": "bitsandbytes",
"ignored_layers": ["to_out"],
},
)
outputs = omni.generate(
"A cup of coffee on the table",
OmniDiffusionSamplingParams(num_inference_steps=50),
)
```
CLI:
```bash
python text_to_image.py --model Tongyi-MAI/Z-Image-Turbo --quantization bitsandbytes
python text_to_image.py --model Tongyi-MAI/Z-Image-Turbo --quantization bitsandbytes --ignored-layers "to_out"
vllm serve Tongyi-MAI/Z-Image-Turbo --omni --quantization bitsandbytes
```
## Parameters
| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `method` | str | - | Quantization method (`"bitsandbytes"`) |
| `quant_type` | str | `"nf4"` | 4-bit data type: `"nf4"` (recommended) or `"fp4"` |
| `compress_statistics` | bool | `True` | Double-quantize block scaling statistics for better accuracy |
| `ignored_layers` | list[str] | `[]` | Layer name patterns to keep in BF16/FP16 |
## Validation and Notes
On Z-Image-Turbo (single GPU, 1024×1024, 50 steps), BitsAndBytes W4 typically
reduces peak VRAM from roughly 24.5 GiB (BF16) to roughly 17 GiB. Compare output
quality against a BF16 baseline before enabling on new models.
Multi-GPU tensor parallelism (`tensor_parallel_size` > 1) is not validated for
BitsAndBytes in diffusion models; each rank quantizes its own weight shard
independently.
If quality regresses, use `ignored_layers` to keep sensitive projections in BF16
(for example `to_out` or `w2`).
```python
omni = Omni(
model="Tongyi-MAI/Z-Image-Turbo",
quantization="bitsandbytes",
cache_backend="tea_cache",
cache_config={"rel_l1_thresh": 0.2},
)
```
Only add a new model to the supported table after comparing the BitsAndBytes
output against a BF16 baseline and documenting any required `ignored_layers`.

Blackwell only** (`sm_100` / `sm_101` / `sm_103`, compute capability `10.x`, e.g.
B200): quack's CuteDSL GEMM uses the 5th-gen `tcgen05` tensor-core MMA, which exists
only on those parts. On Hopper/Ada the CUTLASS FP8 kernel already fuses bias, and on
workstation/consumer Blackwell (`sm_120` / `sm_121`, compute capability `12.x`, e.g.
RTX PRO 6000 / RTX 50-series) `tcgen05` is absent — so quack is **not** auto-enabled
there and FlashInfer's native FP8 path is used instead. Set
`VLLM_OMNI_USE_QUACK_FP8=1` to force quack on, or `VLLM_OMNI_USE_QUACK_FP8=0` to force
the FlashInfer path. If `quack-kernels` is not installed, FP8 still works — it just
keeps the unfused FlashInfer path.

GGUF is static quantization: the quantized weights are produced before serving.
!!! note
GGUF support has migrated to OOT [vllm-gguf-plugin](https://github.com/vllm-project/vllm-gguf-plugin). Make sure you have GGUF plugin installed before serving a GGUF model.
Before serving a GGUF model, make sure to install the [vllm-gguf-plugin](https://github.com/vllm-project/vllm-gguf-plugin):

# AudioX offline inference
Generate audio with the [AudioX](https://zeyuet.github.io/AudioX/) MMDiT diffusion
pipeline (`AudioXPipeline`). Six tasks: `t2a`, `t2m`, `v2a`, `v2m`, `tv2a`, `tv2m`.
## Prerequisites
Download a vLLM-Omni weight bundle (component-sharded safetensors):
```bash
huggingface-cli download zhangj1an/AudioX --local-dir ./audiox_weights
```
The Hugging Face id `zhangj1an/AudioX` also works directly without prefetching.
## Usage
```bash
# Text-to-audio only (default uses zhangj1an/AudioX from the Hub):
python end2end.py --tasks t2a
# All six tasks against a local bundle and a sample video for v2*/tv2*:
python end2end.py \
--model ./audiox_weights \
--video https://zeyuet.github.io/AudioX/static/samples/V2M/1XeBotOFqHA.mp4
# Subset of tasks, custom seed and steps:
python end2end.py --tasks t2a tv2a --num-inference-steps 100 --seed 0
```
## Arguments
- `--model`: HF id or local bundle path (default: `zhangj1an/AudioX`).
- `--tasks`: any subset of `t2a t2m v2a v2m tv2a tv2m` (default: all).
- `--video`: video file/URL — required for `v2*` and `tv2*`.
- `--reference-audio`: optional audio prompt (audio-conditioned generation).
- `--num-inference-steps`, `--guidance-scale`, `--seed`, `--seconds-total`,
`--sample-rate`, `--output-dir`: generation knobs.
Outputs land in `<output-dir>/<task>.wav` as 16-bit stereo WAV.
