GitHub quietly retired GitHub Models on 2026-07-30; Simon Willison discovered it on 2026-08-09 when a GitHub Actions job failed with 'GitHub Models is temporarily unavailable as part of a scheduled retirement brownout.' The service's killer feature was that code running in Actions could call LLMs using the ambient GITHUB_TOKEN with no extra key — the foundation of most 'Continuous AI' workflow demos. GitHub gave no public reason; Willison's read is that coding-agent usage patterns made subsidized tokens unaffordable. If you have CI pipelines that call models via GitHub Models, they are already broken — he migrated to a rate-capped OpenAI key running GPT-5.6 Luna.
