There is an adaptive AI poker bot called Pluribus developed at Carnegie Mellon University which was able to adapt and exploit some of the best players in the world. Similar bots have been developed at MIT and Stanford. However the amount of time and effort it takes to develop bots like these is at least as much the time and effort and depth of knowledge as it takes to become a winning poker player.
Are there any of these adaptive AI bots out there? I can't say for sure. But if they are out there they aren't playing the micros. There's just not enough money in the micros to earn a living or even feel that you're a successful thief. Playing NL10 100 h/hr at 10BB/100 you could make about 1 dollar per hour per table. To make $15 per hour you need to play 15 tables. Doing that all day would be very suspicious.
There are also commercial bots on the market that you can buy for about the price of a HUD, maybe a little more. Now just ask yourself, if you had a bot that worked, would you sell it to others? Or would you use it to make money yourself? Wouldn't sharing it with the world make it more detectable once
poker sites caught onto it?
I took a look at one of these products. They use scripted decision trees that are basically like computer programs 10,000 lines or more with thousands of decisions paths. The decisions are based on holdings, community cards, position, number of players in the pot, bet sizes, etc. They have forums where people share the scripts. You need a good knowledge of poker to program these scripts.
The scripts did not track hand history, generate HUD stats, put ranges on players or adapt play to exploit them. So you basically have a 10,000 line script for ABC poker, which won't adapt to play exploitatively against others and will likely have leaks of its own.
The evaluation license was good for 200 hands. Then you pay $129 for a license. I imagine people try the bot, the bot gets lucky for those first 200 hands and then they think the bot is a crusher. So they fork up the $129 and then never win it back and lose more instead before they find out the bot is a scam.
Then there's the fact when you get caught you get banned. How many new accounts, with new identities, are you going to create and verify so that you can get cashouts?
