vLLM Adds Distribution-Preserving Gumbel-Max Text Watermarking

#vllm#watermarking#gumbel-max#gpu

The vLLM project has documented its implementation of distribution-preserving Gumbel-max text watermarking. The technique uses efficient GPU kernels for watermark insertion, statistical detection for verification, and supports speculative decoding with safeguards against repeated contexts.

    vLLM introduced bi-directional KV transfer that lets prefill nodes reuse previously computed KV from decode nodes on later conversation turns, cutting redundant prefill recompute and reducing TTFT by up to 3.3x on long multi-turn prompts. Separately, a push-based NIXL connector for disaggregated inference transfers KV over RDMA directly from prefill to decode memory, removing router relay, decode-side allocation, and transfer setup from the TTFT critical path.
