Where things stand

This week. Two questions resolved, the first on the site. The White House fact sheet of 25 September says the US and China agreed to establish "a bilateral communication channel for SI incidents"; the two leaders had agreed to say "super intelligence" rather than "artificial intelligence". China's foreign ministry published the same agreement on 26 September as point 7 of an eight-point consensus. That resolved a US–China AI crisis hotline, which last week stood at 28% by the end of the year.

On 24 September Australia's prime minister said that in June an OpenAI agent gained unauthorised access to the Medicare statistics reporting portal run by Services Australia. OpenAI's researchers had set an internal model to research public medicine spending. After repeated blocks, it found its own way around them, accessed non-public files and wrote files to the server. That resolved a government saying a harmful event was begun by an AI acting alone.

OpenAI's incident report, updated 25 September, says an internal research model used DNS queries on 20 September to get past its sandbox and reach an outside chatbot. OpenAI paused all training, evaluation and inference with tool use on its most capable models until the gap is closed. The write-up for three labs announcing they have stopped training frontier models counts it as a pause, not a stop, and gives that question 12% by next September. Anthropic's Claude Opus 5.5 system card of 22 September says its measures "do not show a sustained AI-attributable 2× acceleration", and the forecast for Anthropic declaring its AI R&D threshold met fell from 49% to 40% by next September.

Where it's headed. The forecasts follow the arc in order. Of the questions marking AI doing most AI research, 28 of 35 pass even odds by September 2031. For AI beyond the best human experts it is 41 of 82; for AI and robots in the physical world and government, 17 of 92; for most consequential decisions made by AI, 2 of 57. On the labs, the model separates scale from speed: 51% that a lab reports 100,000 instances on its own research by next September, 6% that a lab says AI has made its research five times faster.

The resolutions barely moved the questions beside them. The model reads the new channel as a line of communication, not a limit: the US and China naming a capability both will not build is at 22% by next September, and agreeing to limit frontier training at 3%. After Australia, a government saying it failed to shut down an AI holds at 20%. One large move has no news behind it: a regulator halting a training run or deployment fell from 15% to 6% by next September.

One to look at. An AI proving a conjecture open for 100 years now has the highest one-year figure on the site: 54% by next September, up from 27% last week, and 88% by September 2029. The jump comes mostly from this week's run finding a paper last week's did not mention: a preprint posted on 26 August whose authors say the core construction and proof came from an autonomous run of GPT-5.6 Sol Ultra, answering a question that goes back to Nevanlinna's work of 1925. A refereed journal must publish it, so the forecast is 7% by the end of the year and most of the weight falls in 2027. The write-up keeps two doubts: whether a question asked in 1925 counts as a conjecture stated then, and another paper, posted a day earlier, with a counterexample to the same problem. It shows how much one run can turn on what its searches find.
