GitHub Models is now retired

Blog · Watch/Read

  • GitHub Models, a unified API and playground for LLMs, has been retired, leading to failures in GitHub Actions workflows that relied on it.
  • GitHub Models was designed to facilitate “GitHub Next’s Continuous AI concept” by allowing GitHub Actions to leverage the existing GitHub API key for LLM prompts.
  • Simon Willison speculates the retirement is likely due to the high cost of “coding agent patterns” making free or subsidized LLM tokens unsustainable for GitHub.
  • Users affected by the shutdown, like Simon, will need to migrate their LLM integrations, for example, by switching to an OpenAI API key and models like GPT-5.6 Luna.
