At TechCrunch Disrupt on October 16, Replit CEO Amjad Masad said the company was no longer working with Anthropic, citing cost, partnership and performance. He said Replit's internal and public benchmarks show OpenAI's Sol and Astra models consistently doing better at building vibe-coded apps from scratch.
Masad later clarified on X and to TechCrunch that "Replit remains model agnostic." Users can still choose Anthropic's Claude and other supported models, but OpenAI is now the preferred partner powering Replit Agent. A person familiar with the Anthropic partnership told TechCrunch it was still in place. TechCrunch notes that a Replit blog post in late September listed Claude models running in Replit Agent's production environment, and that Masad said Replit had been a top-five Anthropic customer until recently.
Masad also said enterprise contracts went from about 2% of Replit's revenue last year to about 15% this year, and that more than half of revenue is now B2B.
