Replit has ended its collaboration with Anthropic, citing various reasons including cost, after previously announcing a partnership with OpenAI.
Replit’s chief executive Amjad Masad announced on stage at TechCrunch Disrupt 2026 that the AI‑coding platform has ended its work with Anthropic. Masad framed the move as a response to “cost, partnership terms and performance” considerations, noting that enterprise contracts now represent roughly 15 percent of Replit’s corporate revenue.
The statement follows Replit’s August rollout of a partnership with OpenAI, which has positioned the OpenAI models as the company’s primary backend for its coding assistants. Until now, Replit’s documentation and a late‑September blog post still referenced Anthropic’s Claude Fable 5 and 5.1 models in production, and an employee’s social post mentioned Opus 5.5, suggesting that Anthropic’s technology remained in use shortly before the announcement.
Why it matters: Replit is a high‑profile platform for developers and startups, and its choice of underlying large‑language models influences the broader ecosystem of AI‑assisted development tools. A shift away from Anthropic signals that cost and performance pressures are prompting developers to consolidate around the most widely adopted models—currently OpenAI’s offerings. The move also underscores the growing importance of enterprise revenue streams in shaping AI‑service contracts.
What to watch next: Replit’s next product updates will reveal how quickly OpenAI’s models replace Anthropic’s in the platform’s feature set and whether the company revisits Anthropic under different terms. Observers will also track any formal statements from Anthropic about the split and monitor whether other developer‑focused platforms follow a similar cost‑driven realignment. As we reported on 17 October, the partnership’s status had already been questioned, and today’s on‑stage confirmation adds concrete rationale and a clearer view of Replit’s strategic direction.
