Replit replaces Anthropic with OpenAI as default AI coding partner

Replit has replaced Anthropic with OpenAI as the default AI model for its Replit Agent platform, CEO Amjad Masad announced at TechCrunch Disrupt. The decision was driven by cost, performance, and partnership factors, with Masad stating ChatGPT now performs better for building applications from scratch. While Anthropic models remain accessible on the platform, OpenAI is now the default choice for new users. This shift follows Replit's August partnership announcement with OpenAI and could significantly reduce Replit's spending with Anthropic, as most customers tend to stick with the default setting.
