We expect the 4.0.14 release will be next week (probably on Tuesday), and is expected to include some fixes to a few infinite loops and some select balance changes (like splitting up Enforcers and Telepaths again). It will be a short work week here in Sweden, so it’s likely to be the only update of the week.
As I mentioned last week, with multiplayer stability largely handled, AI is one of our next focuses. Today I want to talk about AI benchmarks, and have a discussion with you about how we should measure “success”.
What Makes a Good AI?
The AI in Stellaris has always been designed as very reactive, and AI personality has a massive impact on their behavior. Our goal is for our AI empires to feel like actors in the galactic play - acting in a manner consistent with their Origins, Authorities, Civics, and Ethics rather than always picking the “meta” play.
They do still need to put up a bit of a challenge though, especially at higher difficulties.
The first economic goal we make for our AI is “please don’t collapse in an economic death spiral”, and it’s actually far better at that in 4.0 than it was in 3.x. The current AI does NOT meet the second “provide an adequate challenge” goal though.
One of the fundamental tools we have for our AIs are resource targets in their economic plans. They’ll strive to reach those targets, and many of these are set as “scaling” - if they meet the target, they’ll raise the target the next month. This attempts to ensure that they’ll keep thirsting for ever larger research and alloy numbers (or food if they use bioships!) as is appropriate. This is one of the tools we also use to make them exhibit their ethics - Materialists scale their Research targets faster than other empires, so they’ll inherently be more likely to build more Research specializations, while Spiritualists are more likely to have a lot of Unity specializations.
Ironically, improving AI tends to consume any benefits we carved out through performance improvements. The stronger the AI, the more stuff they have - fleets, colonies, and so on.
Benchmarking
One way to decide whether or not the AI is performing up to expectations is through benchmarking - what kind of fleet power, alloy generation, and research generation should they have by 2230, 2250, 2300, and so on? Around what year should they hit 10k fleet power?
Then there come questions around whether the benchmarks should differ based on personality type. Should it be different if they’re Democratic Crusaders vs. Peaceful Traders? Or does differentiating them there make the friendlier empires too weak?
I’ve got my own set of benchmarks that come from running 3.14 and from the multiplayer community, and in general, I’m okay with Grand Admiral being significantly harder than it was in 3.14. but I’m interested to hear what you all strive for.
How much research and alloy production do you try to have 10 years, 30 years, 100 years, and when the end-game crisis comes calling? (Include your preferred difficulty settings and galaxy sizes as well if you could, as well as if you change any other important settings like tech costs.)
What’s Next?
We’re going to continue with 4.0 post release support.
Since the next two weeks are both short weeks in Sweden, our next Stellaris Dev Diary will be June 12th. (You’ll be hearing from me in patch notes in the meantime though.)
