- 发生了什么
- vLLM introduced Hybrid HiSparse, an optimization that offloads GLM 5.3 KV cache to CPU memory selectively, enabling full 1 million context length on 8 H200 GPUs.
- 为何重要
- Engineers deploying agentic workloads with long, growing contexts on limited GPU memory need higher concurrency without preemption or full re-prefilling costs.
- 注意
- Hybrid HiSparse is not yet in standard vLLM releases; it requires building from a specific commit. Speculative decoding hot buffers currently need sizing for all verification tokens simultaneously.
