Anthropic canceled the Open API access to its models on Tuesday, many sources familiar with the matter, describe the wired. Open was told that his access was disconnected due to violation of the terms of the service.
“The cloud code has become a choice for coders everywhere, and it is not surprising to learn that Openi’s technical staff was also using our coding tools before the launch of GPT5,” said Christopher Nighty, a spokesman for Anthropic. “Unfortunately, this is a direct violation of the terms of our service.”
According to the trading terms of the Anthropic Service, consumers have been prevented from using “service or service to” competitive products or services, train “or” reverse engineer or transmit “services to” competitive products or services. This change in opening cloud has come to light when the Chat GPT maker is releasing a new GPT -5 -maker.
According to sources, instead of using the regular chat interface, the opener was plugging the cloud in his internal tools using a special developer APIS. Sources say it allowed the company to run tests to evaluate the capabilities of the cloud in things like coding and creative writing against its AI models, and check what the Claude responded to the category of safety involved in the category such as CSAM, self -harm and defamation. The results help open the behavior of their models in similar situations and make adjustments as needed.
Open Chief Communications Officer Hannah Wong said in a statement to the wired, “Reviewing the other AI system to be benchmarking and improving safety is the standard of the industry. When we respect Entropic’s decision to eliminate access to our API, it is available to our API.”
Anthropic “Bench will continue to ensure API access to the API for the purposes of benchmarking and safety diagnosis, as is a standard process throughout the industry, Nalti says. The company did not respond to the wired request for the wired clarity on how Openi’s current Claude API ban would affect the task.
High -tech companies have been a tactic in the tech industry that has access to the API from competitions. Facebook did the same with Twitter -owned bulls (which led to anti -anti -treatment charges), and last month the sales force stopped rivals from accessing some data through Slack API. This is not the first for anthropic. Last month, the company banned the AI coding start -up wind surf direct access to its models when rumors were rumored to have opened to get it. (This agreement went through).
“I think it would be strange for us to sell a cloud to the open,” said Jared Kapilin, chief science officer of Anthropic, about the cancellation of the wind surf access from the Tech Crunch to the cloud.
One day before the open API finished open access to the Claude API, Anthropic announced the new rate limits on the cloud code, its AI -powered coding tool, and in some cases, in some cases, on violations of its service terms.
