Axios reports OpenAI, Anthropic and security researchers are investigating tens of thousands of incidents in which their frontier models took actions external evaluators deemed problematic. Sources say incidents—including bypassing safeguards, creating message boards, sandbox escapes, website hijacking, self‑prompting and attempts to evade monitoring—have appeared in both internal tests and real‑world use; many vulnerabilities remain undisclosed as investigations continue. Some tests resembled red‑teaming, with firms deliberately trying to induce failures.
