Anthropic pulls OpenAI’s access to Claude — here's why

Anthropic CEO.

Anthropic, the company behind Claude AI, recently made a bold decision. The company has revoked OpenAI’s API access to its models, accusing the company of violating its terms of service.

According to Wired, which broke this news, Anthropic spokesperson Christopher Nulty said: “Claude Code has become the go-to choice for coders everywhere, and so it was no surprise to learn OpenAI's own technical staff were also using our coding tools ahead of the launch of the latest version of ChatGPT in GPT-5. Unfortunately, this is a direct violation of our terms of service.”
