Replit has transitioned its strategic focus from Anthropic to OpenAI as its primary AI partner. CEO Amjad Masad indicated that the decision was driven by cost, partnership terms, and performance, noting that OpenAI models showed superior ability in benchmarks for building applications from scratch.

While Replit was previously one of Anthropic’s five largest customers, OpenAI models have now become the default provider for the Replit Agent tool. Although the partnership with Anthropic remains active and users can still manually select Claude models, the company has moved Anthropic to a secondary position to optimize pricing and development capabilities.
