Anthropic Cuts Windsurf's Access to Claude AI Models Amid OpenAI Acquisition Rumors

Anthropic Restricts Windsurf's Access to Claude AI Models

In a significant development in the AI-assisted coding sector, Anthropic has substantially reduced Windsurf's direct access to its Claude AI models, including Claude 3.5 Sonnet and Claude 3.7 Sonnet. This decision comes amidst swirling rumors of OpenAI's potential acquisition of Windsurf for $3 billion, though neither company has confirmed these reports 1
