In an unprecedented event in the world of artificial intelligence, Anthropic blocked its large competitor’s access to the powerful Claude family models. The move came after the disclosure of Openai’s internal use of anthropic tools to compare and develop its models, including the Gpt-5.
Anthropic has recently discontinued Openai’s API access to Claude family models. The reason for this action is the explicit violation of the conditions of the anthropic service by Openai; Because Openai technical staff have used Claude coding tools to evaluate and develop the GPT-5 model.
Anthropic spokesman said in an official statement to TechcRunch: “Openai’s internal use of our coding tools is a clear violation of our commercial laws; “We do not allow Claude to be used to develop competing services.” However, Anthropic has announced that it will continue to allow Claude to access Openai for the purposes of public safety evaluation and benchmarking.
In contrast, Openai, in response to the decision, described its action as a “industrial standard” and said, “Although we respect the Anthropic decision, this is a disappointing act, because our API has still been open for them.”
This is an obvious sign of close competition between artificial intelligence giants; The competition that has now been drawn from the model of model development to a battle for access, professional ethics and business boundaries.
