Is there any documented bonuses to the AI empires depending on the difficulty settings? Having just finished a surprisingly easy highest difficulty run (Humankind), the only notable difference I ran into was the +2 Combat Strength on their units with the [Difficulty] modifier. I assume it's safe to say there's FIDS modifiers they have, but can't seem to find anything specific. Any ideas?

I'd like to know as well, for me it seems like the AI gets quite a bit of bonis. (judging from their ability to push out units)

Nearly done with an Emperor game and as you said, they get a sizable unit increase, so I wonder if it's a production buff or just extra units every so often. Still not very smart even on high difficulty though lmao
