Just would like to share my experience . it's awful. Chat hallucinating all the time.   Invents  nodes out of a blue .  Some never existed output parameters .    Wrong expressions .   Misguides you all the time .   
So amazing  contrast with Blender where it writes its own addons  , create  node tools  under your requests  or draw you a detailed schemes  of which things should be connected to and how and so on and on .     
Nowaday any pro software should be  friendly with Chat or any other AI in general IMO .   If AI understand nothing   what would you expect of people.

There are almost no written tutorials on designer, the documentation is minimal and adobe burned the forum so it has nothing to work with.
Then the robot makes shit up in an effort to keep you engaged and using tokens
if you want the robot to help you solve problems in designer ask it the same question in a programming language (hlsl for pixel processors) and port the result expression by expression.
