Anthropomorphization cancels Openai The API visited its model on Tuesday, multiple sources familiar with the matter told Wired. Openai was told that his access was cut off due to breach of the Terms of Service.
“Claude code has become the preferred choice for coders everywhere, so it’s no surprise that Openai’s own technicians also use our coding tools before the launch of GPT-5,” said human spokesman Christopher Nulty in a statement on Wired. “Unfortunately, this is a direct violation of our terms of service.”
Under Anthropic’s commercial terms of service, customers are prohibited from using services to “build competitive products or services, including training competitive AI models” or “reverse engineers or duplicates” services. According to reports, there are rumors that this change in openai visits Claude is reported to be reported.
Sources say Openai uses special developer access (API) to plug Claude into its own internal tools instead of using a regular chat interface. This allows the company to evaluate Claude’s capabilities in things like coding and creative writing that is opposite to its own AI model and to examine how Claude responds to safety-related tips involving categories like CSAM, self-harm and defamation. The results help OpenAI compare the behavior of its own models under similar conditions and adjust them as needed.
“Evaluate other AI systems to benchmark progress and improve security. Although we respect Anthropic’s decision to cut off API access, it’s disappointing considering our API is still usable.
Nulty said humans will “continue to ensure OpenAI can be benchmarked and security assessments in accordance with standard practices across the industry.” The company did not respond to Wired’s request to clarify that Openai’s current Claude API restrictions would affect the work.
For years, top tech companies rob API access from competitors has been a strategy in the tech industry. Facebook’s Vines owned by Twitter (which led to allegations of anti-competitive behavior) and Salesforce last month restricted competitors from accessing certain data through the Slack API. This is not even the first one to be anthropomorphized. Last month, the company restricted direct access to AI-coded startup Windsurf after it was rumored to have acquired it. (That deal failed).
At the time, Jared Kaplan, the chief scientific officer of anthropomorphism, spoke with TechCrunch to revoke Windsurf’s chance to visit Claude, saying: “I think it’s weird that we sell Claude to Openai.”
The day before cutting Openai’s access to the Claude API, Anthropic announced new rate limits for Claude Code, its AI-powered encoding tool, citing explosive usage and, in some cases, breach of its Terms of Service.
