Voices are AI-generated
Replit chief executive Amjad Masad said on 15 October 2026 at TechCrunch Disrupt that the AI coding platform no longer works with Anthropic, citing cost, partnership and performance [1]. A person familiar with the partnership told TechCrunch that it is still in place [1].
Why does Amjad Masad say Replit switched?
Masad said Replit's internal benchmark and a public benchmark it publishes show OpenAI's Sol and Astra models perform better at building vibe-coded applications from scratch [1]. Replit announced a partnership with OpenAI in August, but had not said it was leaving Anthropic [1].
It was a decision based on both cost, partnership, and performance.
What contradicts the Replit CEO's claim?
A late-September Replit blog post cites Claude Fable 5 and Claude Fable 5.1 as models running in Replit Agent's production environment, TechCrunch reported [1]. Around the same time, a Replit product employee posted on X about using Anthropic's Opus 5.5 [1]. TechCrunch said it had asked Replit for clarification [1].
How is Replit's revenue mix changing?
Masad said enterprise was about 2% of Replit's revenue last year and about 15% this year, and that more than 50% of revenue is now business-to-business [1]. Replit is not sharing annual recurring revenue figures yet, he said [1].
Our read
Opinion: Whatever the contract says, coding platforms now treat model suppliers as interchangeable and say so on stage. That is also a bargaining signal to both labs.
