Replit makes OpenAI the preferred default behind Replit Agent; CEO Amjad Masad says Claude stays selectable
Onstage at TechCrunch Disrupt 2026, Replit CEO Amjad Masad said the company was no longer working with Anthropic, then clarified on X on Oct 17 that Replit remains model-agnostic: users can still pick Anthropic and other models, but OpenAI is now the preferred partner powering Replit Agent by default, citing performance, cost and partnership. Since most users keep the default, the change is likely to shift a large share of Replit spend between the two labs.
Key Takeaways
