Replit Shifts Default AI Model to OpenAI from Anthropic
Replit has changed its default AI model provider from Anthropic to OpenAI, according to CEO Amjad Masad during a TechCrunch Disrupt event. The decision was based on cost efficiency, performance benchmarks, and partnership strength with OpenAI. While Replit remains 'model agnostic' allowing users access to Anthropic models like Claude Fable 5 and Opus 5.5, the shift is expected to reduce spending with Anthropic as most customers use default settings. Masad noted that enterprise revenue has grown significantly for Replit, rising from about 2% of total revenue last year to around 15% in 2024, with over half now coming from B2B contracts. He also emphasized the importance of AI safety and infrastructure as critical components for deploying agents effectively. Despite Masad's statements, insiders suggest that Replit’s partnership with Anthropic remains active, citing recent blog posts and social media activity promoting Anthropic models.
