What's New

Switch from PDF text repair to LLM inference engine with new models and optimizations

Breaking Changes

  • `--enable-scale-out` is now opt-in on plain `vllm serve`
  • `g_idx` activation ordering removed
  • Deprecated items removed, including env vars and cache modes
  • `all` Mamba cache mode deprecated
  • `python -m vllm.entrypoints.grpc_server` deprecated

New Features

  • DeepSeek-V4.1-Flash and GLM-5.3-Flash models
  • Fast Start IPC cache daemon for persistent GPU weight caching
  • HiSparse host-resident tier for sparse-MLA decode
  • Gumbel-max watermarking with keyed PRF
  • K2-Horizon and Cohere Compass model support

Improvements

  • Model Runner V2 dual-batch overlap and FULL CUDA graphs
  • Targeted online quantization and W4A16 DSA support
  • Improved performance for Qwen3.8-Flash-Next
  • Async Engram prefetch with DP sharding
  • Rust frontend forwarding per-request controls

Upgrade Notes

Enable `--enable-scale-out` explicitly if scaling is required. Use `vllm serve --grpc` instead of the deprecated module. Remove deprecated environment variables like `VLLM_PREFIX_CACHE_RETENTION_INTERVAL`.
