Replit ends partnership with Anthropic, CEO cites cost

Replit has ended its working partnership with Anthropic, according to company CEO Amjad Masad. Masad cited several factors behind the decision, among them cost considerations tied to using Anthropic’s models within the coding platform.

The change follows Replit’s August announcement of a partnership with OpenAI. At the time of that announcement, there was no public indication that Replit’s relationship with Anthropic had ended or was ending. TechCrunch AI reported the development on October 16, 2026, attributing the account to Masad’s statement.

The report does not detail the specific technical or financial terms that prompted the split, nor does it specify whether Anthropic’s models will be removed entirely from Replit’s offerings or phased out over time. Masad’s comments, as reported, frame the decision as resulting from “a number of different reasons,” cost being one named factor among others left unspecified.

Replit, a browser-based coding and app-development platform, has built features around large language models supplied by outside AI labs. Anthropic and OpenAI compete directly in supplying such models to software companies. The shift places Replit’s coding tools under OpenAI’s models following the earlier partnership announcement, with Anthropic’s prior role in the platform now ended according to its CEO’s account.
