Agents don't have access to screenshots, as we are purely evaluating text-only models. All reasoning is conducted over object representations of the game (with positions etc).

I have anecdotally tried using screenshots to help models debug their factories, but without training a custom CNN/ViT on the Factorio UI, the visual outputs miss critical things (e.g gaps in transport belts).

That said, we have demonstrated via unit tests that the API is technically sufficient to progress to a rocket launch alone. We have been able to complete most lab tasks using the API ourselves so the humans still have a hefty lead here! The ones that we didn't do are the late-game lab tasks, which would have taken significant time and which frontier models are far from being able to complete.
