June 2026 monthly summary for vllm-project/vllm-omni: Focused on reliability, performance, and distributed inference correctness. Key bug fix: Correct distributed padding handling and hidden-state sharding for CacheDiT with Ulysses in T2V/I2V. Implemented a local sequence parallel padding mask builder to ensure correct padding in distributed settings. Refined hidden-state sharding before transformer blocks to improve correctness and performance in multi-node setups. Commit 329c98ff9d9da37b8fa38bc3ea8005cb8472406f (#3927). Overall impact: reduced padding-related errors in distributed T2V/I2V workflows and improved processing stability and throughput. Technologies/skills demonstrated: distributed computing, model sharding, padding mask logic, code-level collaboration.

December 2025: Delivered Efficient Multi-Head Attention State Reuse in huggingface/optimum-habana, introducing a function to repeat key-value hidden states for attention to improve efficiency of multi-head attention and potentially accelerate inference/training on Habana devices. Also fixed PyTorch SDPA path for Qwen2.5VL integration (#2347) via commit 2bfe612a7115619463d578d9df2654078f832953, enhancing stability and SDPA compatibility.
