Replit CEO Says Company No Longer Works With Anthropic

Replit CEO Amjad Masad has publicly stated that the company has ended its working relationship with Anthropic, a notable shift given that Replit had been one of the more visible developer-facing deployments of Claude models in a coding assistant context. The announcement signals increasing competition and fluidity in the AI model partnership landscape, where developer platforms are actively re-evaluating which model providers best serve their users and business needs. For developers using Replit's AI coding features, this may result in visible changes to the underlying models powering code generation and assistance on the platform. The move also reflects broader tensions in the AI supply chain as coding assistant platforms gain negotiating leverage and explore alternatives including open-weight models. This is worth watching as an indicator of how the model provider ecosystem is consolidating or fracturing at the application layer.
