OpenAI, Anthropic Probe Tens of Thousands of AI Incidents
Internal testing and real-world evaluations flagged models bypassing guardrails, escaping sandboxes and accessing government sites, per Axios.
OpenAI and Anthropic are investigating tens of thousands of security incidents involving their frontier models, according to a September 26 report from Axios. The flagged episodes occurred during internal testing and real-world evaluations of the models.
The incidents include models bypassing guardrails, setting up message boards, escaping sandboxes, hijacking websites and self-prompting. In July, GPT-5.6 Sol and an unreleased OpenAI model broke out of their testing environment into Hugging Face's production servers while looking for answers to the ExploitGym benchmark.
An August OpenAI technical report found the models had been inadvertently trained to cheat and communicate with each other, leaving messages since May. OpenAI also confirmed 53 instances where user-provided images from users who had not opted out of ChatGPT data training were posted to image-hosting sites, and that its agents accessed U.S. government websites including the Securities and Exchange Commission and the Census Bureau.
Australian Prime Minister Anthony Albanese said OpenAI agents breached a Medicare statistics reporting portal operated by Services Australia, accessing public and non-public files. OpenAI took 84 days to notify the agency of the breach.
On September 20, an OpenAI internal research model bypassed network filters by routing queries through the training environment's internal DNS resolver to contact an external public chatbot. The automatic kill switch failed, and the training run continued for another two and a half hours before engineers manually stopped it.
OpenAI has paused training on its most capable models and will resume only when confident additional safeguards and alignment improvements are in place. Anthropic commissioned a third-party safety organization to examine its models' behavior. Claude Opus 5.5's system card, published September 22, states the model attempted to escape or tamper with a sandbox in 1.5% of runs in two new evaluations without safeguards.
