vLLM Adds Day-0 Support for Kimi K3.1 Pro with Sparse Attention and Packed KV Cache

#vllm#kimi#sparse attention#kv cache

vLLM announced day-0 support for Kimi K3.1 Pro, enabling sparse attention on a KDA hybrid, a packed KV cache with FP8 or NVFP4 latents and MXFP4 index keys, token-sharded prefill, decode context parallelism, and fused low-latency decode. This integration allows users to run the model immediately upon release with optimized performance.
