• The ai only needs 4/5 of the production that humans do.
  
• The ai cities take less food surplus to grow.
  
• The ai has infinite range on missiles.
  
• The ai bombers don't have to refuel.
  
• The ai can choose which techs it wants to steal, even with diplos.
  
• The AI can choose what improvement to sabatoge, even with diplos.
  
• The ai can steal multiple techs from the same city.
  
• Ai units have spy/diplo functions.
  
• The ai can build units on the same turn it discovers the tech for it.
  
• Ai democracies can't be overthrown by double civil disorders or sneak attacks on other nations.
  
• The ai does not have senate intervention.
  
• The ai knows the whole map.
  
• The ai can contact you when it isn't their turn.
  
• The ai treasuries are randomly created.
  
• The ai doesn't get unhappiness as much as humans.
  

If you have more, send 'em in.

On king level, the AI have the same base rates that humans do (first tech = 10 beakers, warrior = 10 shields, food bin has 10 rows). On lower levels, the AI is handicapped by taking longer to do things, and on higher levels, such as Diety, the AI needs less time.

As for Annoying AI traits - how about its ability to expel/insist removal of units within your city limits if it has a city overlapping in any way, while you are unable to do likewise.

Don't forget, humans have at least one cheat; we get notified when AI is about to build a Wonder.

* The AI can bribe democratic units
* The AI can on occasion beat Barbarians at incredible odds (I've seen AI Warriors take out fortified Barb Riflemen)
* The AI knows exactly when it can mess up your production by occupying a city square
* The AI has intimidating envoys while you never get to see yours

2) The AI always has King-level happiness.

3) This could be bitterness talking, but I think the AI gets occasional combat bonuses vs the human on Deity. I've had a catapult take out a rifleman behind city walls. I've also heard someone metion that in one game they played, the AI regularly won every seventh battle in attacking a city, regardless of odds.

4) I don't think the AI treasuries are random. debeest is correct in saying the AI doesn't pay maintainance, and this explains their remarkable financial position.

5) The AI can irrigate without needing water at hand.

That's all I can think of for now.

• The ai only needs 3/5 of the production that humans do.
  
• The ai cities take less food surplus to grow.
  
• The ai has infinite range on missiles.
  
• The ai bombers don't have to refuel.
  
• The ai can choose which techs it wants to steal, even with diplos.
  
• The AI can choose what improvement to sabatoge, even with diplos.
  
• The ai can steal multiple techs from the same city.
  
• Ai units have spy/diplo functions.
  
• The ai can build units on the same turn it discovers the tech for it.
  
• Ai democracies can't be overthrown by double civil disorders or sneak attacks on other nations.
  
• The ai does not have anarchy periods.
  
• The ai can have a revolution when it's not their turn.
  
• The ai knows EVERYTHING.
  
• The ai can contact you when it isn't their turn.
  
• The ai does not spend money on upkeep.
  
• The ai always has King-level happiness
  
• The ai can expel troops that are in your city radius if it is in theirs too.
  
• AI triremes don't sink. Forgot about that one .
  
• AIs can bribe a democracy.
  
• Ais can irrigate without water.
  
• The AI can go into deficit.
  

The AI appears to be able to bribe human units at little or no cost, as compared to the exorbitant rates usually charged to humans for AI units. Cities, too, maybe, but I haven't been able to study that.

AI capitals can move freely at no apparent cost, although in my experience the AI always has to pay the 1000 gp to replace a sacked capital.

The AI cannot (in my experience) bribe a Democratic unit or city in version 2.42 and later (there was a bug that allowed this to happen in earlier versions).

As has been said above I believe that the AI needs 60% of human production only at deity when the human is in front on the powergraph under other conditions than this the AI needs a higher proportion ...

Keep up the good work

Really? I was under the impression that it couldn't improve terrain even when it does have one.

I was testing the winning every 7th battle (something that obviously doesn't work) and I stumbled across this by accident!

(having trouble with your dl caesar...)

The deity production/food cheat is a handycapping, and is documented as being intended. Should that be excluded from this list?

When the AI founds a city it will sometimes get a square irrigated and roaded right from the start. I am not sure what causes this. I used to think it was because of a lack of grassland squares, but I don't think that is the case now.

I had not seen that the AI doesn't pay maintenance. Has that been thoroughly tested?

Also, not on the list but I think someone mentioned: AI democracies don't have a senate to deal with. I've seen them declare war without changing gov't and without UN.

And what about infinite cruise missile supply when you approach their shore with a Battleship or Carrier.

Some other comments:

As Sten mentioned, you can get AI bombers to crash from lack of fuel, but only if the bomber chooses to attack a unit after its first turn in the air. Otherwise, AI bombers can hang out forever, but they can't hurt you.

The AI is affected by pollution. It's just that their cities don't generate pollution.

I've seen infinite range nuclear missiles, but not cruise missiles.

As debeest alluded to, both the human and the AI can relocate their capitals for 1000 gold. The AI cheats in that it can relocate it's capital in the middle of someone else's turn.

If an AI were to take my capital, I would lose any spaceship in flight and likely begin my next turn with much disorder, corruption, and waste. I could then, on my turn, rebuild my capital for 1000 gold (and then wait until my next turn for construction to be complete). If they grounded my spaceship, I'd have to start a new spaceship from scratch too.
