# Updating the AI

Now that the beta is out in the wild (and up until now I haven’t heard any big complaints) it’s time to finally bring the AI in line with all the changes in “Phase 2. In the last beta, roughly 90% of the AI code was the same as in “Phase 1” and so the current AI isn’t much of a challenge.

So I just started rewriting most of the AI code for the next beta, and one of the areas the AI was always lacking (already in “Phase 1”) was building construction. Today I did a complete rewrite of how the AI handles construction inside of regions and the new version is much better, more dynamic and produces results that look much more human than the old one which would produce the same cityscapes over and over again.

Here are the changes for the new AI builder :
