The team chose code synthesis: models write Python that invokes high-level Factorio actions, including moving to distant locations and placing entities relative to one another.

“So that forced us to think a bit more carefully about what interface we could expose to these models,”

“and we ultimately settled on a code synthesis.”

“approach where these models would write python code and those python code in that python code would invoke certain high level actions such as move to this distant point or place an entity next to another entity and you'd leave it up to the model to think about how to abstract these tooling abstract these actions into a structure that would give it”
