Replit makes OpenAI its default over Anthropic, CEO says

Replit has made OpenAI its default AI model provider, replacing Anthropic in that role, according to comments from CEO Amjad Masad reported by TechCrunch AI over the weekend. Masad clarified the change amid questions about the coding platform’s relationship with Anthropic, whose Claude models had previously served as Replit’s standard offering.

Claude will remain available to Replit customers who choose to use it, the report states, meaning the shift concerns the default setting presented to users rather than an outright removal of Anthropic’s models from the platform.

TechCrunch frames the move within the broader competitive landscape among AI model providers, noting that default-provider status carries weight because it shapes which company’s models developers and businesses encounter first, and by extension, use most often when building on platforms like Replit.

The report does not detail the commercial or technical reasons behind Masad’s decision, nor does it specify when the change takes effect or whether pricing, performance, or partnership terms played a role. It also does not indicate whether Anthropic was consulted or responded to the shift.

The dispatch is limited to Masad’s public statement and TechCrunch’s framing of its significance for the industry’s balance among competing model providers.
