Replit CEO says it no longer works with Anthropic, citing cost and performance
Replit co-founder and CEO Amjad Masad said onstage at TechCrunch Disrupt that Replit is no longer working with Anthropic, citing cost, partnership and performance, and adding that "ChatGPT is better now"; he said both its internal benchmark and a public benchmark consistently show Sol and Astra perform better at building vibe-coded applications from scratch. Replit announced a partnership with OpenAI in August, and there had been no indication its Anthropic relationship had ended, though one person familiar said the partnership is still in place and a September blog post still cited Claude Fable 5 and Claude Fable 5.1 in Replit Agent's production environment. Masad also said enterprise contracts grew from about 2% of revenue last year to roughly 15% this year, with B2B now more than half of revenue, and argued agents need a habitat with good orchestration, error recovery, safety, sandboxing and identity controls.
How AI coding platforms pick among model providers shows how cost, performance and partnership terms shape which frontier models mainstream developer tools actually use.
