What happened
Replit announced that it is no longer working with Anthropic and has entered a partnership with OpenAI that was disclosed in August.
OpenAI's ChatGPT is now the default model on the platform, though customers can still access Anthropic models, and the change was motivated by considerations of cost, partnership benefits, and performance.
AIBeat analysis
This could lower operating expenses for developers using Replit, as the default model may be cheaper, and the partnership might bring performance improvements, while still offering Anthropic options for those who prefer them.
