Anthropic公司据报道因服务条款违规而切断了OpenAI的API访问权限。多方消息称，OpenAI利用Anthropic的Claude代码来协助开发和测试其即将发布的GPT-5模型。OpenAI被指控通过API接口而非聊天界面，利用Claude的内部工具进行测试，以评估GPT-5在编码和创意写作方面的表现，并测试了与CSAM、自残和诽谤相关的安全提示。此举旨在为GPT-5获取数据以提升其与Claude的竞争力。然而，这违反了Anthropic的服务条款，该条款禁止客户利用其工具构建竞争性产品，包括训练竞争性AI模型。OpenAI回应称此举是行业标准，并尊重Anthropic的决定，但对其API访问被关闭表示失望，尤其是在Anthropic仍可访问OpenAI API的情况下。OpenAI表示其API访问将被恢复用于基准测试和安全评估。

🎯 Anthropic切断OpenAI API访问权限：据报道，Anthropic公司因OpenAI违反服务条款而终止了其API访问。据称，OpenAI利用Anthropic的Claude代码来辅助开发和测试其即将发布的GPT-5模型。

💻 OpenAI利用Claude API进行测试：消息人士指出，OpenAI并非通过聊天界面，而是直接通过API接口接入Claude的内部工具，以运行测试并评估GPT-5在编码和创意写作方面的性能，并对安全提示（如CSAM、自残、诽谤）进行测试。

⚖️ 违反服务条款与OpenAI的回应：OpenAI此举违反了Anthropic禁止利用其工具构建竞争性产品（包括训练竞争性AI模型）的服务条款。OpenAI则回应称，这是AI行业的标准做法，并表示尊重Anthropic的决定，但对API访问被关闭感到失望，并表示其API访问将恢复用于基准测试和安全评估。

🔗 Anthropic过往的API限制举措：这不是Anthropic首次切断API访问。此前，该公司曾因Windsurf可能被出售给OpenAI而切断其API访问。此外，Anthropic还调整了Claude的速率限制，部分原因是用户违反了共享和转售账户的政策。

It seems OpenAI has been caught with its hands in the proverbial cookie jar. Anthropic has reportedly cut off OpenAI’s access to Anthropic’s APIs over what Anthropic is calling a terms of service breach. 

As reported by Wired, multiple sources claim that OpenAI has been cut off from Anthropic’s APIs. Allegedly, OpenAI was using Anthropic’s Claude Code to assist in creating and testing OpenAI’s upcoming GPT-5, which is due to release in August. 

According to these sources, OpenAI was plugging into Claude’s internal tools instead of using the chat interface. From there, they used the API to run tests against GPT-5 to check things like coding and creative writing against Claude to compare performance. OpenAI allegedly also tested safety prompts related to things like CSAM, self-harm, and defamation. This would give OpenAI data that it could then use to fine-tune GPT-5 to make it more competitive against Claude. 

Unfortunately for OpenAI, this violates Anthropic’s commercial terms of service, which ban companies from using Anthropic’s tools to build competitor AI products. 

“Customer may not and must not attempt to access the Services to build a competing product or service, including to train competing AI models or resell the Services except as expressly approved by Anthropic,” the terms read.

OpenAI responded by saying that what the company was doing was an industry standard, as all the AI companies test their models against the competing models. The company then went on to say that it respected Anthropic’s decision but expressed disappointment in having its API access shut off, especially considering that Anthropic’s access to OpenAI’s API remains open. 

A spokesperson told Wired that OpenAI’s access would be reinstated for “benchmarking and safety evaluations.”

It’s not the first time this year that Anthropic has cut off API access. In June, the company cut off Windsurf’s API access after rumors that it was being sold to OpenAI. That deal ultimately fell through, but Anthropic’s cofounder, Jared Kaplan, told TechCrunch at the time that “it would be odd for us to be selling Claude to OpenAI.”

Anthropic has also tweaked its rate limits for Claude, which will take effect in late August, with one of the reasons being that a small number of users are violating the company’s policy by sharing and reselling accounts.
