Anthropic restricts Windsurf's Claude access

Anthropic / Windsurf · 3 June 2025

Windsurf says Anthropic cut nearly all first-party capacity to Claude 3.x models on under five days' notice, amid reported OpenAI acquisition.

Shows how much power a model supplier holds over coding tools, since a rival's pending owner lost direct access. Anthropic cited prioritizing 'sustainable partnerships', and co-founder Jared Kaplan said selling Claude to OpenAI would be odd and cited compute limits.

Windsurf also lacked direct access to Claude 4 at launch. The Kaplan quote comes from secondary reporting (the-decoder, via search), not opened.
