The convenient model API disappears

GitHub retired its model playground, catalog, inference API and bring-your-own-key service on July 30. Existing customers lost access too.

Simon discovered the change when a GitHub Actions job stopped generating summaries for his research repository. The appeal had been wonderfully mundane: an Action could call models using the GitHub credential already available in its environment.

His replacement was an OpenAI API key with a monthly spending limit. The automation survived; one convenient assumption did not.

Simon suspects agent workloads made subsidized tokens expensive. GitHub did not give that as its explanation, so it remains a hypothesis.

A useful reminder for small AI utilities: the cheapest integration to set up can still become a dependency worth isolating. Keeping the model call easy to replace paid off here.
