Latest News 🔥

• [2026/04] Version 0.19.0 is now available, built on vLLM 0.19.0 and fully compatible with Intel® Gaudi® v1.24.0 with PyTorch 2.10.

  This release upgrades the platform to Intel® Gaudi® Software v1.24.0 with PyTorch 2.10. It introduces Qwen 3.5 model support, Mamba prefix caching for hybrid models, MxFP4 weight dequantization, LMCache integration, and a custom depthwise conv1d TPC kernel for MambaMixer2. Performance improvements include torch.compile-compatible online defragmentation, improved warmup time, and optimized hybrid KV cache visibility.

• [2026/04] Version 0.17.1 is now available, built on vLLM 0.17.1 and fully compatible with Intel® Gaudi® v1.23.0.

  This patch release backports critical fixes and improvements including MxFP4 weight loading, Granite 4.0-h calibration, prefix caching for HPUMambaMixer2, OOM crash fixes, and SDL secure error handling improvements.

• [2026/03] Version 0.16.0 is now available, built on vLLM 0.16.0 and fully compatible with Intel® Gaudi® v1.23.0.

  This release introduces validated support and critical stability fixes for Qwen3-VL models leveraging HPUMMEncoderAttention. Performance and stability were improved through backported Mamba architecture optimizations, Docker and UBI infrastructure enhancements, and a forced CPU loading mechanism for INC quantization to prevent OOM errors.

About

The vLLM Hardware Plugin for Intel® Gaudi® integrates Intel® Gaudi® AI accelerators with vLLM to optimize large language model inference. It follows the [RFC]: Hardware pluggable and [RFC]: Enhancing vLLM Plugin Architecture principles, providing a modular interface for Intel® Gaudi® hardware. For more information, see the Plugin System document.

Getting Started

1. Set up your execution environment. Additionally, to achieve the best performance on HPU, follow the methods outlined in the Optimizing Training Platform Guide.

2. Get the last verified vLLM commit. While vLLM Hardware Plugin for Intel® Gaudi® follows the latest vLLM commits, upstream API updates may introduce compatibility issues. The saved commit has been thoroughly validated.

   git clone https://github.com/vllm-project/vllm-gaudi
   cd vllm-gaudi
   export VLLM_COMMIT_HASH=$(git show "origin/vllm/last-good-commit-for-vllm-gaudi:VLLM_STABLE_COMMIT" 2>/dev/null)
   cd ..

3. Install vLLM using pip or build it from source:

   # Build vLLM from source for empty platform, reusing existing torch installation
   git clone https://github.com/vllm-project/vllm
   cd vllm
   git checkout $VLLM_COMMIT_HASH
   pip install -r <(sed '/^torch/d' requirements/build/cuda.txt)
   VLLM_TARGET_DEVICE=empty pip install --no-build-isolation -e .
   cd ..

4. Install vLLM Hardware Plugin for Intel® Gaudi® from source:

   cd vllm-gaudi
   pip install -e .
   cd ..

5. Install torchaudio (required by some upstream vLLM models such as QWEN3_5). Use the CPU wheel with --no-deps to avoid pulling a conflicting CUDA torch:

   pip install --no-deps torchaudio --extra-index-url https://download.pytorch.org/whl/cpu

   To see all the available installation methods, such as NIXL, see the Installation guide.
