I think that's reading a little too much into it. The paper shows the hidden states contain signals about whether the code is good right now, and whether the run is probably going to work out. That's interesting, for sure. But it doesn't mean the model has some detailed idea of what it's going to write 25 steps later.

A lot of that signal could be much simpler stuff. This task is hard. The agent seems stuck. The tests are getting better. The current approach looks promising. All of those things make future success easier to predict without the model actually "knowing what comes next" in any strong sense.

Also, their 25 steps are agent turns, not 25 code edits. The median run had something like 52 steps but only two edits, and the program label stays the same between edits. So "25 steps ahead" may sometimes just mean basically the same codebase, with a bunch of reading and test output in between.

So yeah, I'd say it's consistent with Sutskever's view. But "consistent with" and "confirmatory of" are doing very different amounts of work here.

I think that's the practical implication. Whether it's "thinking ahead" or not, if the model can reliably predict a failing trajectory several agent turns in advance, an agent could backtrack or branch much earlier instead of spending tokens on a dead end. That seems more interesting than the terminology debate.
