GitHub Models
Frontier and open models for free using only your GitHub token
GitHub Models gives every GitHub account rate-limited free inference against a catalogue of models (OpenAI GPT family, Llama, Mistral, Phi, and more) through an OpenAI-compatible endpoint. Auth is a GitHub personal access token with the models:read scope; no separate billing or card is needed for free usage.
Free tier
Free for experimentation, tied to your GitHub account (no card). Opt in to paid usage for production-grade limits and larger context.Rate limits
Free, per-account, varies by model tier (verified June 2026, Copilot Free): high-tier models 10 RPM / 50 req/day; low-tier models 15 RPM / 150 req/day; embeddings 15 RPM / 150 RPD. Per-request token caps apply (e.g. 8000 in / 4000 out on low models). Limits subject to change.Auth
