Replit made OpenAI the default model provider for Replit Agent, and its CEO said the company had been a top-five Anthropic customer until recently
Amjad Masad said on stage at TechCrunch Disrupt that Replit was no longer working with Anthropic, citing cost, partnership and performance, and that OpenAI's Sol and Astra models scored higher on Replit's public benchmark for building apps from scratch; over the weekend Replit said it remains model-agnostic, that Claude is still selectable, and that OpenAI is now its preferred partner for powering the agent. A person familiar with the Anthropic partnership told TechCrunch it was still in place; Masad also said enterprise went from about 2% of revenue last year to about 15% this year.
why it mattersDefault model choices at the big coding platforms are now set by price and benchmark score and can flip in a quarter, so keep your own agent workflows provider-agnostic and expect the model behind any hosted tool to change under you.
