Overview

• Anthropic ended Windsurf’s direct access to its Claude 3.x models with less than five days' notice after reports of OpenAI’s $3 billion acquisition deal.
• Windsurf CEO Varun Mohan announced the cutoff on X, expressing disappointment despite the startup’s willingness to pay for full capacity.
• Users can still access Claude through Windsurf’s bring-your-own-key system and the platform has promoted alternative models including Google’s Gemini 2.5 Pro at reduced rates.
• Anthropic co-founder Jared Kaplan said the company is reserving its constrained computing resources for long-term partners and called it odd to support a rival’s acquisition of Windsurf.
• Kaplan added that Anthropic plans to increase model availability in the coming months and is focusing development on agentic coding tools such as Claude Code.
