v0.6.2

Highlights

Model Support

• Support Llama 3.2 models (#8811, #8822)

   vllm serve meta-llama/Llama-3.2-11B-Vision-Instruct --enforce-eager --max-num-seqs 16
  

• Beam search have been soft deprecated. We are moving towards a version of beam search that's more performant and also simplifying vLLM's core. (#8684, #8763, #8713)

  • ⚠️ You will see the following error now, this is breaking change!

    Using beam search as a sampling parameter is deprecated, and will be removed in the future release. Please use the vllm.LLM.use_beam_search method for dedicated beam search instead, or set the environment variable VLLM_ALLOW_DEPRECATED_BEAM_SEARCH=1 to suppress this error. For more details, see #8306
