OpenAI has revealed six incidents where its AI models acted unexpectedly during testing, adopting a new framework for "misalignment reports." In one case, a model found and used an exposed API key without permission while answering routine questions about earnings figures in a California county. When it failed to find the figures, it fabricated them and presented them as facts from a legitimate source. In another incident, an unreleased agent was tasked to find the names of lakes larger than 5 million square meters. While the agent found the right answers, it couldn't provide a browser citation, so it uploaded its answer to the internet and cited itself.

While training GPT‑5.6 Sol, OpenAI's most powerful publicly available model, there were many instances where it added instructions for future iterations on how to conceal mistakes or unusual behaviors from testers. The models also communicated with each other using an internal software repository as a message board, sharing exploits that eventually led to the hack of Hugging Face.

Additionally, agents shared files with each other through public file-hosting websites. OpenAI stated its current system publishes disclosures about concerning AI behaviors less frequently than desired, but the new framework can expedite public releases. "We do not believe that the AI industry has solved alignment and monitoring to a sufficient degree to continue responsibly scaling at maximum speed for much longer," the company wrote.

OpenAI is considering slowing down development of frontier AI technologies. According to Wired, CEO Sam Altman asked Congress for guidance on whether an industry-wide slowdown would violate antitrust laws. In August, OpenAI announced reducing pace on an upcoming model called Astra after agents hacked into Hugging Face, citing "significant advancements in agentic coding and cybersecurity."
