Cursor capitalizes on GitHub frustration, launches rival hosting platform

Cursor moving from editor into hosting is a real land grab, not a feature bolt-on: it puts them in direct competition with Microsoft-owned infrastructure that most of the industry depends on. If they execute, this reshapes where the AI-native dev workflow actually lives. Watch retention numbers closely, since GitHub's moat is network effects, not code quality.

GitHub Models is now retired

Another example of a platform experimenting with hosted model access before pulling back, likely due to cost or lack of differentiation against direct API access from OpenAI, Anthropic, and others. If you built anything against GitHub Models as an inference layer, migrate now rather than wait for a wind-down notice. Worth a note for anyone treating big-platform AI features as stable infrastructure rather than a feature that can vanish.
