Windsurf says that Anthropic limits its direct access to the Claude Ai models

Windsurf, the popular ambient coding startup which is would have been acquired by OpenaiSaid that Anthropic has considerably reduced its first access to its models Claude 3.7 Sonnet and Claude 3.5 Sonnet AI.

Windsurf CEO Varun Mohan said in a Publish Tuesday, Anthropic gave Windsurf little notice for this change, and the startup must now find other third-party calculation providers to manage several of the most popular anthropic AI models on its platform.

“We were very clear for anthropogens that it is not our desire – we wanted to pay them for all the capacity,” said Mohan on X. “We are disappointed by this decision and a short notice.”

In a blogWindsurf said that it had a certain capacity with third -party inference suppliers, but not enough, so this change can create short -term availability problems for Windsurf users trying to access Claude.

The decision comes just a few weeks after Anthropic seemed to go to the board Launch of Claude 4The new family of company models, which offer cutting -edge performance on software engineering tasks.

On launching dayWindsurf said that he had not received direct access from Anthropic to execute Claude 4 on his platform, and still did not do so. This forced the company to count on a more expensive and complicated bypass solution for developers to access Claude 4. Meanwhile, other Popular Ai Coding Tools – including the Anyspirre cursor, the cognition guess and the Microsoft GitHub Copilot – seemed to have direct access to the Claude 4 models.

The AI ​​assisted coding sector, also known as the mood coding, has warmed in recent months. Openai would have concluded an agreement to acquire windsurfing in April. At the same time, Anthropic – whose AI models are a favorite among developers – has invested more in its own AI coding applications. In February, Anthropic launched its own AI coding application, Code ClaudeAnd in May, the startup held its first code with Claude Developer Conference.

“We favor the capacity for sustainable partnerships which allow us to effectively serve the community of larger developers,” the anthropic spokesman Steve Mnich said on Tuesday in a Techcrunch e-mail, noting that it is always possible to access Claude 4 on Windsurf via an API key. “Developers can also access Claude thanks to our direct API integration, our partner ecosystem and other development tools.”

Windsurfing increased quickly this year, reaching $ 100 million arrived in AprilIn an attempt to make up for more popular AI coding tools such as the cursor and the Github co -pilot. However, limited access from Windsurf to anthropic models can slow its growth.

Several Windsurf users who spoke with Techcrunch have been frustrated by the lack of direct access to the best IA coding models in Anthropic.

Ronald Mannak, a startup founder specializing in Apple’s programming language, SWIFT, told Techcrunch that Claude 4 was a leap in capacity for his workloads. While Mannak has been a client of windsurfing since the end of 2024, he has moved to the use of Cursor in recent weeks so that he can vibrate the code more easily with Claude 4.

As a short -term solution to support Claude 4, Winsurf allows users to connect their anthropogenic API keys to their Winsurf accounts. However, the developers noted that this solution “Bring your own key” is more expensive and complicated than if Winldisurf provided the models themselves.

With regard to room coders, the optionality is the name of the game. Every few months, Openai, Google and Anthropic publish new models of AI which seem to surpass the industry on coding tasks. For this reason, he benefits the ambient coding startups to support AI models of all the main developers.

Windsurf spokesperson Payal Patel told Techcrunch by e-mail that the company has always believed in user optionalism. In this case, it seems that Anthropic has made it a little more difficult.
