What happened
GitHub Models has been fully retired, breaking any GitHub Actions workflows that relied on its unified LLM API and the ambient GitHub API key for prompt execution. Simon Willison discovered this via a failed Actions run and migrated his README folder-summary workflow to an OpenAI API key with a monthly spending limit, using GPT-5.6 Luna.
Why it matters
If you have GitHub Actions workflows calling GitHub Models for LLM prompts, they are already broken—audit your repos and swap in a direct provider API key with spending caps. Willison's guess that coding-agent usage made subsidized tokens prohibitively expensive is a signal that other free-tier LLM gateways tied to CI/CD may follow.
Discussion angle
Which other free or subsidized LLM-in-CI offerings are still safe to build on, and what's the cheapest fallback pattern for agent workflows that need an API key in GitHub Actions without racking up unbounded spend?
