Replit makes OpenAI its default model provider, replacing Anthropic

· Tech · United States

Replit has made OpenAI its default model provider, replacing Anthropic, according to CEO Amjad Masad. Masad clarified over the weekend that OpenAI would take over as the platform's default, while Anthropic's Claude will still be available to customers on the platform. The switch matters because Replit is a coding platform where developers build and run software with AI assistance, so its default choice shapes which model most users encounter. It also shows that competition among AI labs for default placement in developer tools remains fluid, even as Anthropic keeps a presence on the same platform.

Why it matters：Default model choices in developer platforms steer which AI labs gain usage and feedback, and the Replit switch shows those positions can change quickly.

Key points

  • CEO Amjad Masad disclosed the change over the weekend.
  • Claude will remain available to Replit customers.
  • The default applies to a platform developers use to build software.
