v0.6.3

Highlights

Model Support

• New Models:
  • Text: Granite MoE (#8206), Mamba (#6484, #8533)
  • Vision: GLM-4V (#9242), Molmo (#9016), NVLM-D (#9045)
  • Reward model support: Qwen2.5-Math-RM-72B (#8896)
• Expansion in functionality:
  • Add Gemma2 embedding model (#9004)
  • Support input embeddings for qwen2vl (#8856), minicpmv (#9237)
  • LoRA:
    • LoRA support for MiniCPMV2.5 (#7199), MiniCPMV2.6 (#8943)
    • Expand lora modules for mixtral (#9008)
  • Pipeline parallelism support to remaining text and embedding models (#7168, #9090)
  • Expanded bitsandbytes quantization support for Falcon, OPT, Gemma, Gemma2, and Phi (#9148)
  • Tool use:
    • Add support for Llama 3.1 and 3.2 tool use (#8343)
    • Support tool calling for InternLM2.5 (#8405)
• Out of tree support enhancements: Explicit interface for vLLM models and support OOT embedding models (#9108)

Documentation

• New compatibility matrix for mutual exclusive features (#8512)
• Reorganized installation doc, note that we publish a per-commit docker image (#8931)

Hardware Support:

• Cross-attention and Encoder-Decoder models support on x86 CPU backend (#9089)
• Support AWQ for CPU backend (#7515)
• Add async output processor for xpu (#8897)
• Add on-device sampling support for Neuron (#8746)

Architectural Enhancements

• Progress in vLLM's refactoring to a core core:
  • Spec decode removing batch expansion (#8839, #9298).
  • We have made block manager V2 the default. This is an internal refactoring for cleaner and more tested code path (#8678).
  • Moving beam search from the core to the API level (#9105, #9087, #9117, #8928)
  • Move guided decoding params into sampling params (#8252)
• Torch Compile:
  • You can now set an env var VLLM_TORCH_COMPILE_LEVEL to control torch.compile various levels of compilation control and integration (#9058). Along with various improvements (#8982, #9258, #906, #8875), using VLLM_TORCH_COMPILE_LEVEL=3 can turn on Inductor's full graph compilation without vLLM's custom ops.

Others

• Performance enhancements to turn on multi-step scheeduling by default (#8804, #8645, #8378)
• Enhancements towards priority scheduling (#8965, #8956, #8850)
