Replit CEO Says Company Dropped Anthropic for OpenAI, But Insiders Dispute the Claim

At TechCrunch Disrupt on Thursday, Replit CEO Amjad Masad told the audience the company is no longer working with Anthropic, citing cost and saying 'ChatGPT is better now' for building vibe-coded apps on Replit's internal benchmarks (where he said OpenAI's Sol and Astra now outperform Claude). A source familiar with the deal pushed back, telling TechCrunch the partnership is still in place and noting that Claude Fable 5.1 and Opus 5.5 are visible in Replit's production environment as recently as late September. Replit publicly added OpenAI as a model provider in August.
