Practical overview
When it fits
Use it when you want to run a supported model through vLLM on an Apple Silicon Mac and can meet the macOS requirement.
Who it is for
- Developers building local language-model inference or serving setups on Apple Silicon.
- Teams already using vLLM that want to explore its Apple Silicon hardware path.
- Contributors working on Python or kernel code for the plugin.
Documented uses
- Serve supported language models locally through vLLM on an Apple Silicon Mac.
- Use the plugin's Metal attention implementation in a local serving stack.
- Explore speculative decoding in an Apple Silicon vLLM configuration.
Requirements & limits
The source repository specifies an Apache-2.0 license. The README documents stable installation with Homebrew and a separate installer for the latest development build.
- Requires Apple Silicon and macOS 15 or later.
- Model support varies; consult the project's supported-model matrix.
- The stack separates responsibilities: vLLM provides the API server and scheduling, mlx_lm supplies token-wise model layers, and Vllm Metal owns the request-aware attention path.
- Stable and development builds have different documented installation paths.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Install the stable Vllm Metal release
Install the stable release on a supported Apple Silicon Mac.
Before you start
- An Apple Silicon Mac running macOS 15 or later
- Homebrew
Steps
Add the vllm-metal Homebrew tap: brew tap vllm-project/vllm-metal https://github.com/vllm-project/vllm-metal
Install the package: brew install vllm-project/vllm-metal/vllm-metal
Expected outcome
The stable Vllm Metal release is installed; the README says to run vllm without activating an environment.
Guide limitations
- This installation procedure does not specify model selection or serving commands.
- Supported models vary; check the project's model matrix.
Install the latest development build
Install the development build and activate its documented environment.
Before you start
- An Apple Silicon Mac running macOS 15 or later
Steps
Run the project's installer: curl -fsSL https://raw.githubusercontent.com/vllm-project/vllm-metal/main/install.sh | bash
Activate the environment: source ~/.venv-vllm-metal/bin/activate
Expected outcome
The development build's environment is activated.
Guide limitations
- The README labels this the latest development build, not the stable release.
- The supplied setup instructions do not cover serving a model.
