Anthropic revoked OpenAI’s API entry to its fashions on Tuesday, a number of sources aware of the matter inform WIRED. OpenAI was knowledgeable that its entry was minimize off resulting from violating the phrases of service.
“Claude Code has grow to be the go-to alternative for coders all over the place, and so it was no shock to be taught OpenAI’s personal technical employees have been additionally utilizing our coding instruments forward of the launch of GPT-5,” Anthropic spokesperson Christopher Nulty stated in a press release to WIRED. “Sadly, it is a direct violation of our phrases of service.”
In keeping with Anthropic’s industrial phrases of service, clients are barred from utilizing the service to “construct a competing services or products, together with to coach competing AI fashions” or “reverse engineer or duplicate” the providers. This alteration in OpenAI’s entry to Claude comes because the ChatGPT-maker is reportedly making ready to launch a brand new AI mannequin, GPT-5, which is rumored to be higher at coding.
OpenAI was plugging Claude into its personal inner instruments utilizing particular developer entry (APIs), as a substitute of utilizing the common chat interface, in response to sources. This allowed the corporate to run exams to judge Claude’s capabilities in issues like coding and inventive writing towards its personal AI fashions, and examine how Claude responded to safety-related prompts involving classes like CSAM, self-harm, and defamation, the sources say. The outcomes assist OpenAI evaluate its personal fashions’ habits below related circumstances and make changes as wanted.
“It’s business customary to judge different AI techniques to benchmark progress and enhance security.

Fb did the identical to Twitter-owned Vine (which led to allegations of anticompetitive habits) and final month Salesforce restricted opponents from accessing sure knowledge by way of the Slack API. This isn’t even a primary for Anthropic. Final month, the corporate restricted the AI coding startup Windsurf’s direct entry to its fashions after it was rumored OpenAI was set to accumulate it. (That deal fell by way of).
Anthropic’s chief science officer Jared Kaplan spoke to TechCrunch on the time about revoking Windsurf’s entry to Claude, saying, “I believe it will be odd for us to be promoting Claude to OpenAI.”
A day earlier than reducing off OpenAI’s entry to the Claude API, Anthropic introduced new fee limits on Claude Code, its AI-powered coding software, citing explosive utilization and, in some instances, violations of its phrases of service.
