Llamafile Distribution is a groundbreaking approach to running large language models (LLMs) directly on your computer. It combines llama.cpp with Cosmopolitan Libc into a single-file executable, simplifying the process of using open LLMs for both developers and end users. This executable, known as a “llamafile,” requires no installation and runs locally, ensuring that no data leaves your computer. The platform supports various operating systems and CPUs, and even provides GPU support. For Windows users, external weights can be used to circumvent the 4GB file size limit. Additionally, llamafile offers an OpenAI API compatible chat completions endpoint and extends it with specific features like mirostat. Despite its simplicity, users should be aware of certain system requirements and potential issues, which are detailed in the “Gotchas” section. Llamafile represents a significant step towards making LLMs more accessible and user-friendly.
