Like Webizen says, the AI does an OK job, I've seen worse, a lot worse. The AI is pretty good at manuevering and evading and enveloping your forces... till a certain point that is. The AI *will* build Flak when you build planes, it will also do some stupid things. It has problems with the naval aspect of the game. Having said that, I only play against the AI, and have done so for many years now, it's no real challenge for me now anymore but I still love the game so I keep playing it.
So yeah the AI is as decent as they come. You probably will get clobbered the first few times, AI+ can be a challenge, even for me, AI++ is boring because the AI swamps you with units like a Zerg rush.
