A suspended developer account turned into a public OpenAI and Anthropic exchange

One developer’s suspended account turned into a public exchange between OpenAI and Anthropic, complete with a job offer in the first line.

How a walkthrough became a suspension

Tibo Sottiaux, who leads Codex at OpenAI, had published a walkthrough for running GPT-5.6 Sol inside the Claude Code harness. Developer Alex Getman followed it almost exactly. Shortly afterward, Anthropic suspended his account. He filed an appeal, then tagged both companies asking what had happened.

Sottiaux replied that he would love to help but does not work at Anthropic, and that it seemed odd to ban someone for using their harness with another model.

Anthropic’s answer opened with a job offer

Boris Cherny, who leads Claude Code, responded: “We are hiring if you would like to work at Anthropic! We don’t ban people for using harnesses with other models. Almost certainly it was a different account classifier that triggered. Looking into it, thanks for escalating.”

Sottiaux turned the offer down, saying he is not going anywhere because he loves his team too much, and then reset usage limits for paying ChatGPT Work and Codex users. Sam Altman joined the thread as well.

The question underneath the banter

The exchange was friendly, but it surfaced a real and unresolved question about coding agents. The harness, the model and the subscription are now three separable things. A developer can run one company’s model inside another company’s tooling, on a third arrangement of payment, and the companies themselves have not decided how much of that mixing they will tolerate.

In this instance the answer, per Cherny, was that mixing is fine and the suspension came from an unrelated classifier. That is reassuring for this one account. It is less clear as policy, because it took a public thread involving two product leads and a CEO to establish it. As agent harnesses become the default way developers work with models, where the compatibility lines sit, and how bans get reviewed when automated classifiers fire, will matter to far more people than one developer with a suspended account.
