Replit makes OpenAI its default over Anthropic, CEO says

AI coding platform Replit has largely shifted away from its partnership with artificial intelligence firm Anthropic, citing cost, performance, and partnership dynamics. Replit CEO and co-founder Amjad Masad announced the change at TechCrunch Disrupt, stating that OpenAI is now the preferred partner for powering the company’s automated coding assistant, Replit Agent.

Masad explained that internal and public benchmarks showed OpenAI models performing better for building applications from scratch. Following the conference, Masad clarified that customers can still manually select Anthropic models on the cloud-based development platform, but OpenAI’s ChatGPT is now the default option. This default status is expected to reduce Replit’s spending with Anthropic, a former top supplier whose Claude models previously powered the platform and helped drive revenue growth.

Despite the CEO’s announcement, insiders familiar with the matter disputed that the collaboration had ended, pointing to recent promotional blog posts and social media updates highlighting Anthropic products. Meanwhile, Replit reported broader business growth, with enterprise contracts jumping from two percent of revenue last year to fifteen percent this year.
