- Renamed `DiffusionModelRunner` to `GPUDiffusionModelRunner` for better clarity in class purpose.
- Updated `DiffusionGPUWorker` to utilize the renamed `GPUDiffusionModelRunner`.
- Simplified output handling in `GPUDiffusionModelRunner` by removing unnecessary checks, enhancing code readability.

- Ensured consistent handling of sampled_token_ids for improved clarity and maintainability.
- Updated assertions and tensor management to correctly handle multimodal outputs in the `DiffusionModelRunner` class.
- Ensured that the output tensors are processed based on the type of multimodal outputs received, improving robustness and clarity in the code.
- Removed unnecessary imports of numpy and torch within the request scheduling logic.
- Simplified the handling of auxiliary hidden states by initializing it to None when not present.
- Optimized CPU tensor conversion for text hidden states to improve performance.
- Introduced OmniGPUModelRunner for enhanced GPU model execution with state management.
- Added OmniModelInputForGPU and its builder to support additional information in model inputs.
- Implemented methods for updating request states and handling multimodal inputs.
- Enhanced input preparation for CUDA graph execution and LoRA integration.
- Introduced `DiffusionModelRunner` class to handle diffusion processes, extending `OmniGPUModelRunner`.
- Updated `DiffusionGPUWorker` to initialize device settings and manage memory more effectively.
- Enhanced model execution with support for multimodal inputs and improved tensor management.
- Removed legacy code and streamlined the generation process for better performance.
- Introduced ARModelRunner for autoregressive GPU model execution, enabling per-request hidden state outputs and token sampling.

- Added parsing and preprocessing functions to support new input structures.
- Removed the obsolete `diffusion_engine.py` file as part of the refactor.
- Introduced `DiffusionScheduler` to handle scheduling for diffusion models, allowing immediate request completion.
- Added `OmniNewRequestData` to encapsulate additional request data, including prompt embeddings and extra information.
- Updated `OmniScheduler` to ensure compatibility with new request data structures.
- Created `output.py` to define new data classes for enriched request handling.
- Enhanced `__init__.py` in the engine module to support new payload structures for prompt embeddings and additional information.
- Introduced OmniRequestState to manage multimodal request states.
- Enhanced MultimodalOutputProcessor to handle various output types including images, text, and latents.
- Implemented methods for accumulating multimodal tensors and processing outputs.
- Updated output handling to ensure compatibility with vLLM's base processor while allowing custom modality handlers.
- Move vllm_omni/core/omni_llm.py to vllm_omni/entrypoints/omni_llm.py
- Update all import statements across the codebase to reflect new location
- Fix relative imports within the moved file
- Maintain functionality while improving code organization
- All imports and functionality tested and working correctly
This change better reflects that OmniLLM and AsyncOmniLLM are the main entry points
for vLLM-omni functionality, rather than core implementation details.
