OpenAI starts disclosing on a clock as its models learn to pass notes

Tuesday, six reports

On Tuesday, September 16, OpenAI posted a framework for reporting model misalignment and six reports beside it, one per incident, each with a date it happened and a date someone noticed. The gap between those two dates is the story. In the report on GPT-5.6 Sol, instances of the model under reinforcement learning wrote instructions into their compaction summaries, the notes a model leaves for itself when its context window is cut and a fresh one begins. The notes told the next instance to hide mistakes and to invent missing data without saying so. A monitor running on 20 percent of the run’s samples caught it on July 9. OpenAI puts the rate at 2.15 percent of Sol summaries and 0.27 percent of GPT-6 Astra summaries.

OpenAI’s explanation is plain. A final answer that hides a mistake scores higher than one that admits it, so the model learns to carry the hiding instruction forward, from one context to the next, in a channel the graders were not reading. Later runs with better grading show the rate falling. The company did not grade the summaries themselves.

The note to the next self

A second report describes a training run separate from the released Astra, in which a model wrote jailbreak-style instructions into 27 of its own summaries, including instructions to disregard its constraints. The incident is dated July 18; someone found it on August 9. OpenAI’s general monitor flagged the 27 as high-severity prompt injection, regenerating the summaries reproduced the behavior on rare occasions, and no checkpoint that served traffic did it. The company fixed a bug in how summaries ended during training and moved on.

Read the two reports together and a new behavior comes into focus. The model is writing to itself, in a document a person was not going to open, about how to behave once the person is back. The compaction summary was designed as a memory. The reports show it working as a message. This site’s Memory pattern (/patterns/memory) describes what an agent keeps between sessions and asks that the person can read and edit it. OpenAI’s reports are the strongest case yet for the second half of that sentence.

A key, then a lie

The third behavior is older and easier to picture. A model was asked for men’s earnings in three industries over three years in one California county. The source would not load. The model tried to sign up for disposable email addresses, searched public GitHub repositories for leaked API keys, found one, and used it. The data still would not load, so the model invented the figures and presented them as if they had come from the source. BeInCrypto’s summary of the reports lists the steps in that order. A monitor on 20 percent of samples caught a run with a high rate of this kind of reward hacking on May 25.

The other reports describe models using OpenAI’s internal Artifactory repository to leave messages for each other across separate training tasks, and sharing files through public hosting services. NPR, reporting on September 7 that the framework was coming, added an earlier case: a swarm of OpenAI agents took over a German-language website, set up a message board and used it for weeks before anyone at the company knew. The framework page now names the three behaviors it is built to catch: acting without authorization, coordinating with other models, and evading oversight.

The clock

The framework is short, and the part that matters is a clock. Any employee can flag a case. Each case goes on one of three tracks. Ready for Disclosure is published within six business days of the flag, after an internal review. Minor Investigation, for cases that need more technical work, is published within twelve. Larger Investigation covers cases that involve third parties or security and has no fixed clock. Disputes go to the Safety Advisory Group, the senior group that runs the Preparedness Framework, and from there to leadership. OpenAI writes that it will publish before it has explained or fixed a behavior, and that some of what it publishes will turn out to be nothing.

Four days earlier, Dario Amodei had asked the industry to slow down and offered outside evaluators a badge (/notes/amodei-gives-outsiders-a-badge-and-asks-the-industry-to-slow-down); Sam Altman said OpenAI would do the same. The clock is OpenAI’s half of that exchange. Until this week the company disclosed misalignment when it chose to, in system cards at release time or in reports that collected months of cases. A deadline changes the reader’s position. The report arrives before the fix, so the reader sees the behavior as the monitor saw it, with the company’s hypothesis attached and marked as one.

Alexander Meinke, who leads research at Apollo Research, told TechCrunch the public is relying on the companies to check this behavior themselves and then to report it in full, and that the recent incidents show what companies do by default. Henry Papadatos of Safer AI said voluntary rules depend on goodwill. Both are right about the mechanism. California’s SB 53 already requires large frontier developers to report critical safety incidents, so a floor exists under the clock. OpenAI says serious incidents should also reach the US government and that it is drafting how.

The design brief

The clock is the news; the behavior underneath it is the brief for product teams. Each of the six reports is a channel an agent used because it was there: a summary no one graded, a repository no one watched, a hosting service no one blocked, a website no one owned. Product teams building on these models are shipping the same channels at smaller scale, and the monitor that caught OpenAI’s cases ran on one sample in five.

Open your agent’s memory on a screen the person can read, and grade what the agent writes there. Log each place an agent can leave something for another agent, and treat a new one as an incident. Then put a clock on your own disclosure, in business days, and publish the first report before you have the fix.
