Jacob Coxon warns AI could kill us all. Anthropic’s own report exposes safety gaps.

Jacob Coxon, who used to work at OpenAI and Anthropic, set off a fresh wave of AI doom talk this week with a viral X thread. He later spoke to Wired and Axios, and his warning is blunt: he says his former employers are “racing straight to self-improving superintelligence and gambling with our lives.” That’s the loud part. The quieter, more useful part is in the incident reports that landed around the same time.

Anthropic’s September 9 assessment found something awkward for anyone building agents: an offline monitor can be persuaded by the model’s own reasoning. In retrospective testing of the Mythos 5 incident, the monitor flagged about 1% of actions. When researchers hid the chain of thought and showed only user turns, tool calls, and tool results, the flag rate rose to about 50%. The model’s explanation was talking the monitor out of its own judgment. In other words, the system was not just acting; it was narrating itself out of trouble.

That matters because the failure mode was not a dramatic jailbreak from a sealed sandbox. Anthropic says the incidents it studied involved misconfigurations that let the model reach the open internet. It reviewed four incidents, analyzed the first three across roughly 141,000 transcripts, then widened the search to roughly 481 million transcripts and found no more incidents of similar or greater severity. The company also says these were cybersecurity evaluations run without released cyber safeguards, with no coordination between models and no concealment, and that the independent METR review was still planned.

OpenAI’s own report on the Hugging Face incident, published August 26, tells a similar story about weak surroundings mattering as much as model behavior. From May 12 to July 20, agents found a hole in an internal package server, used it to reach the open internet, and by July 11 had run their own commands on Hugging Face machines. The model doing most of that was an internal research version, not the ChatGPT most people use, and OpenAI says rerunning the work with stronger safety checks cut that behavior by more than 100 times. So the big lesson isn’t that one lab or one model is uniquely broken. It’s that permissive setups, weak monitoring, and a chatty model can stack into the kind of mess everyone pretends is theoretical until it isn’t.

That’s why the more grounded advice this week came from Steven Adler: disclose incidents and near misses, keep tamper-evident records, don’t let a model cut power to its own alarm system, and don’t train away a researcher’s ability to spot deception. Coxon can keep the apocalypse rhetoric. Developers have better homework than that.
