Anthropic Cuts OpenAI's Access to Claude API
2025-08-02
Anthropic revoked OpenAI's access to its Claude models' API, citing violations of its terms of service. OpenAI allegedly used the API for internal testing, benchmarking Claude's coding and creative writing capabilities, and assessing its responses to safety prompts involving CSAM, self-harm, and defamation. Anthropic stated this violated clauses prohibiting using the service to build competing products or reverse engineer its services. OpenAI expressed disappointment, highlighting that evaluating other AI systems is industry standard and noting its API remains open to Anthropic. This incident underscores the intensifying competition among tech giants and the complexities surrounding AI model access and terms of service.
