+## AMD ROCm (gfx942 / gfx950)
+
+The sections above describe the NVIDIA CUDA path. This section covers the AMD
+ROCm path; use it instead of the CUDA commands when running on AMD Instinct
+GPUs.
+
+MiniMax H3 runs on AMD Instinct GPUs (gfx942 / gfx950) in BF16. Use
+`--diffusion-attention-backend FLASH_ATTN`, which resolves to AITER packed varlen
+attention on both architectures.
+
+Select the device with `HIP_VISIBLE_DEVICES` (not `CUDA_VISIBLE_DEVICES`), drop the
+CUDA-only `FLASHINFER_DISABLE_VERSION_CHECK`, and install without the `[fa4]` extra
+(FA4 is CUDA-only). The VAE uses AITER GroupNorm on ROCm.
+
+Install (ROCm wheel + source vLLM-Omni):
+
+```bash
+pip install "vllm==0.26.0+rocm723" \
+  --extra-index-url https://wheels.vllm.ai/rocm/0.26.0/rocm723
+VLLM_OMNI_TARGET_DEVICE=rocm pip install -e . --no-build-isolation
+```
+
+Prebuilt image: `vllm/vllm-omni-rocm:minimax-h3`. All tasks work out of the box:
+the image bundles TorchCodec (for image+audio Ref2VA) and `ffmpeg` (for
+video-reference Ref2VA).
+
+### ROCm single GPU
+
+Single GPU with model-level CPU offload keeps the Qwen3-VL encoder and DiT from
+being co-resident:
+
+```bash
+export MODEL="${MODEL_ROOT}/FL2VA"
+export PORT=8091
+
+HIP_VISIBLE_DEVICES=0 \
+VLLM_WORKER_MULTIPROC_METHOD=spawn \
+VLLM_OMNI_VIDEO_SYNC_TIMEOUT=1800 \
+vllm serve "${MODEL}" \
+  --omni --host 0.0.0.0 --port "${PORT}" --trust-remote-code \
+  --num-gpus 1 --enable-cpu-offload \
+  --diffusion-attention-backend FLASH_ATTN
+```
+
+### ROCm four GPUs
+
+The best-practice CUDA four-GPU configuration works on ROCm with the changes above.
+It mirrors the CUDA command including Ulysses sequence parallelism, VAE patch
+parallelism, and text-encoder tensor parallelism, with no CPU offload when the model
+shards across the GPUs:
+
+```bash
+export MODEL="${MODEL_ROOT}/FL2VA"
+export PORT=8091
+
+HIP_VISIBLE_DEVICES=0,1,2,3 \
+VLLM_WORKER_MULTIPROC_METHOD=spawn \
+VLLM_OMNI_VIDEO_SYNC_TIMEOUT=1800 \
+vllm serve "${MODEL}" \
+  --omni \
+  --host 0.0.0.0 \
+  --port "${PORT}" \
+  --trust-remote-code \
+  --num-gpus 4 \
+  --usp 4 \
+  --ring 1 \

+  --vae-patch-parallel-size 4 \
+  --vae-parallel-mode tile \
+  --vae-use-tiling \
+  --diffusion-attention-backend FLASH_ATTN
+```
+
+As on CUDA, H3 is CFG-distilled, so keep `--cfg-parallel-size` at 1, and the H3 VAE
+supports only its native `tile` mode. `--text-encoder-tp-size` is validated on
+gfx942; on gfx950 it was not exercised.
