- Replit CEO Amjad Masad said onstage at TechCrunch Disrupt that Replit is no longer working with Anthropic, citing cost, partnership, and performance as the deciding factors.
- Masad said Replit's internal benchmarks show OpenAI's Sol and Astra models consistently perform better at building vibe-coded applications from scratch, adding that "ChatGPT is better now."
- Replit announced a partnership with OpenAI in August, though the company gave no public indication at the time that it was moving away from Anthropic.
- Insiders familiar with the Anthropic-Replit partnership rejected Masad's characterization, telling TechCrunch the partnership was still in place.
- Replit's website and social channels show the company was using Anthropic's Claude Fable 5 and 5.1 models as recently as late September, with a product employee publicly promoting Opus 5.5 on X around the same time.
- Masad said enterprise contracts have grown from about 2% of Replit's revenue last year to roughly 15% this year, with more than 50% of revenue now coming from B2B customers.
Why it matters: The announcement is openly contested: Replit's CEO says the Anthropic partnership is over while Anthropic insiders say it remains intact, and Replit's own late-September blog posts and employee tweets show active Claude model use. If the split is real, Replit — which previously credited Anthropic with significant revenue growth — is consolidating its AI stack with OpenAI, the rival whose models Masad now claims benchmark better.
