Our take

GitHub Models lets you hit GPT-4.1, Llama, Mistral, and xAI behind your GitHub PAT for free. Read the fine print: the free tier caps context at 8K/4K — even on GPT-4.1 — and tops out at 50 req/day on the big models. Wrong tool for production. Right tool for one-token multi-provider experiments.
