Intel has been quietly transforming the AI landscape by making advanced open-source frameworks like PyTorch, Hugging Face Transformers, vLLM, and SGLang fully compatible with its Intel® Xe GPUs right from day one. With the launch of Gemma 4, Intel’s close collaboration with the open-source community—through kernel optimizations and feature enablement—ensures a smooth and high-performance experience for developers and AI enthusiasts alike. This article explores the capabilities of Gemma 4 on Intel hardware, practical setup instructions, and the broader implications for AI deployment.
Gemma 4: Key Features and Hardware Support
Gemma 4 leverages two attention mechanisms across its layers: sliding attention and full attention. Intel Xe GPUs support vLLM attention kernels in Triton out-of-the-box, while Flash Attention kernels, optimized via Intel SYCLTLA, provide additional performance boosts. Hugging Face Transformers users can also access both attention variants directly through PyTorch kernels without additional configuration.
The MoE (Mixture of Experts) pathway in Gemma 4 relies on the highly optimized FusedMoE backend. Intel has upstreamed optimized FusedMoE kernels, making MoE layers instantly functional on Intel Xe GPUs across vLLM and Hugging Face Transformers frameworks.
Gemma 4 also includes the Vision Tower and Audio Tower, transformer models running on Hugging Face Transformers, fully enabled on Intel Xe GPUs, facilitating image and audio processing capabilities without extra tuning.
Getting Started with vLLM
Setting up vLLM on Intel GPUs involves building Docker images from the latest main branch. With PR 38826 merged, developers can clone the vLLM repository, build the Docker image with Intel GPU support, and run it in privileged mode with GPU access.
Once inside the container, the latest Hugging Face Transformers can be installed. Intel Arc® Pro B60 GPUs support multiple configurations, from single-card runs with smaller Gemma models (like gemma-4-E2B-it and gemma-4-E4B-it) to multi-card tensor parallelism for larger models (like gemma-4-31B-it and gemma-4-26B-A4B-it).
Launching OpenAI-Compatible vLLM Server
vLLM provides an HTTP server implementing OpenAI’s Completions API and Chat API, allowing seamless interaction with models via text, image, and audio inputs. Examples include:
Text Generation: Simple queries like “How are you?” generate responses directly from the AI model.
Image Captioning: Users can input an image URL, and Gemma 4 describes it in one sentence.
Audio Captioning: Audio inputs can be summarized in natural language with just one command.
Hugging Face Transformers Setup
Developers can set up Hugging Face Transformers in a virtual environment, install the XPU PyTorch packages, and configure model parallelism. Scripts like test.py support text generation, image captioning, and audio captioning, with flexible tensor parallelism options to fully utilize Intel Arc® GPUs.
Large models benefit from multi-card setups, while smaller models run efficiently on a single card. Commands like torchrun with –tp-size enable easy scaling across multiple GPUs for complex AI workloads.
