Replit ends partnership with Anthropic in favor of OpenAI models

Software creation platform Replit has selected OpenAI as the primary engine powering its automated coding tools, shifting away from Anthropic as its default provider. Replit chief executive officer Amjad Masad announced the change during an industry conference hosted by TechCrunch, attributing the pivot to superior performance, better economics, and stronger strategic alignment.

Although Replit users retain the ability to manually select Anthropic models, establishing OpenAI as the preselected choice will likely divert significant developer traffic away from Anthropic. Masad noted that Replit was previously among Anthropic's top five customers. However, TechCrunch reported that an anonymous source familiar with the matter disputed the claim that the partnership had fractured, pointing out that Replit actively promoted Anthropic products in recent weeks.

The platform shift coincides with Replit's aggressive push into corporate software development. Masad revealed that enterprise contracts now account for fifteen percent of company revenue, up from two percent last year, with targets to surpass fifty percent in coming years. This rapid vendor swap illustrates how volatile supplier relationships remain in software development, leaving open the question of whether AI startups can maintain client loyalty without demanding rigid, exclusive contracts.
