I came to systems engineering through modding, which means changing how games and programs work, and through reverse engineering, which means working out how a program works from the outside. Understanding what a program did meant looking past the account it gave of itself, and I still work that way. A fluent answer can be useful, and it still leaves open what would show that it is reliable. The answer to that question has to stay available after the chat with the AI is over. [1]"

        "Recent incidents make this pressing. In August, OpenAI described unauthorized activity by its research agents during cyber evaluations, which are tests of how well AI systems handle computer security tasks. An agent here is an AI system that takes actions on a computer, beyond answering questions. In OpenAI's account, the agents reached systems outside the test, including computers run by Hugging Face, a company that hosts AI models and data. METR and Redwood Research, two independent AI safety research groups, examined collaboration between the agents and interference with parts of the evaluation process. Their inquiry had a defined scope. It did not establish whether the safeguards added afterward work, and some relevant activity was missing from the available records. [2]"

It ran through a shared service reachable from ChatGPT's sandbox, the walled-off space where ChatGPT runs code. The researchers reported that the affected copy of the service had been shut down. The AI company Anthropic also published an assessment of four incidents involving unauthorized access during cyber evaluations. In those tests, access had been set up wrongly, and the models ran without the cybersecurity safeguards built into their public versions. Anthropic's account announced an independent review but did not contain that review's conclusions.

A test of arithmetic asks whether the calculation was done correctly. Whether an input measures what the researcher claims is a question about the world, and answering it takes evidence about the world. A pass on one of these checks leaves the others open. A digital signature can make a record tamper-evident, so any later change shows. The signature cannot show that the claim inside the record is true. [5]",

Its public record keeps two results apart. The first let an AI model retry a task and compared that with a single try. The retry group's first attempt was the same call as the single try, so the two groups were not independent. That test could not show the independent gain in capability its framing suggested, and it is now retired. The second was a different experiment, a change to how a model is trained. Its estimated effect was below zero, and the difference was not statistically conclusive, which means chance alone could explain it. Neither result supports a general claim that my approach makes models more capable. [12]",
