Distributed Layerwise Offload: Scaling Toward 200B+ DiT Models Efficiently in vLLM-Omni

- What happened
- vLLM-Omni released Distributed Layerwise Offload, enabling 200B+ video generation models to run across multiple GPUs or NPUs with minimal memory overhead.
- Why it matters
- Engineers deploying large diffusion models like Cosmos3-Super that exceed single-device memory should evaluate this for production video generation workloads.
- Watch out
- AllGather synchronization adds overhead; pure-DP without AllGather may outperform in some topologies. Requires vLLM 0.27.0 and vLLM-Omni v0.27.0rc1 or later.
