GitHub Models is now retired (Simon Willison)
blog post · Story page
GitHub retired GitHub Models, the playground and unified model API that let Actions workflows run prompts on the GitHub API key already in the environment. Willison migrated his repository-summary workflow to OpenAI and bets the shutdown fits a pattern: coding-agent usage made free or subsidized tokens prohibitively expensive to offer.
In plain words
- GitHub shut down its GitHub Models service, which let people try several artificial intelligence systems through one connection.
- Programs running automatically on GitHub could previously send instructions using the access key already available there.
- The author moved his automatic folder-summary process to OpenAI and set a monthly spending limit.
- The author suspects coding agents, artificial intelligence systems that perform programming tasks independently, made free or discounted usage too expensive.
