What it does

GitHub Models lets developers try and compare AI models from OpenAI, Meta, Microsoft, Mistral, DeepSeek and others, in a playground on GitHub and through an API that uses a GitHub personal access token. It is meant for prototyping and experiments, for example to test prompts before building an app. Free for every GitHub account, with daily and per-minute request limits per model that depend on your Copilot plan; paid usage is available for more.
