OpenAI was provided access to Anthropic’s AI models through its API, which might not seem anything out of the ordinary because this move can be treated similar to publications allowing ChatGPT to access exclusive content, but the artificial intelligence startup reportedly violated Anthropic’s Terms of Service by benchmarking its competitor’s Claude Large Language Models to gauge the performance of its own LLM. As expected, Anthropic cut off access as the data could be used to develop a more capable service, giving OpenAI a massive advantage in this race.
The latest report states that OpenAI was using several of Anthropic’s tools to determine its own LLM’s capabilities, forcing its access to be severed
Coming to the terms of using Anthropic’s Claude, Wired reports that the commercial conditions of using the program forbid competitors from enhancing products or training rival models. In short, OpenAI was leveraging Claude to develop a competing AI model, which eventually meant that the company’s access would be revoked. As for the tools that were used, the report states that OpenAI’s technical team was taking advantage of Claude Code, Claude’s coding toolkit, via developer APIs to support development of GPT-5.
However, Anthropic was not cut off access completely, as its states that OpenAI will still be able to perform ‘benchmarking and safety evaluations.’ An OpenAI spokesperson has said that while the firm respects Anthropic’s decision to cut off its API access, it is ‘disappointing’ because the company’s API is still available with its competitor. As reported by TechCrunch, Anthropic executives are less than thrilled about sharing technology with OpenAI.
The company behind ChatGPT recently acquired Windsurf, a coding startup, forcing Anthropic to sever access for the firm. This move is similar to what Facebook did with Vine and Salesforce in limiting data access. Assuming Anthropic would have allowed OpenAI access to its tools, the latter would eventually be able to develop LLMs that provide better coding and writing services, and that is just the tip of the iceberg.
