Well, I've not been talking about it because it keeps beating me in an embarassing fashion and I rather thought I'd keep that to myself.
IOW, I've found it excellent. I'm not a beta-tester, BTW, just a 100-turner, but I've seen it doing an excellent job with things like following up one line of research to a useful degree instead of spreading the RPs around too thinly to make a difference.
It does seem to have a tendancy to launch attacks identical to ones which have already failed. Many times, I'll find an identical class ship making another try against, say, a space station which just ate the attacker's sister ship for lunch Last turn.
Of course, it will eventually pull out all the stops and send in a force large enough to crush that station into titanium dust, and I suppose all those puny attacks dotted about could be intended to keep me from knowing where the big one is landing . . .
But, nah, I think it just doesn't correct failed attack strategies quickly enough!
Other than that, I've been finding it a nicely difficult opponent.
