Each Quell(er) version is reguarly updated, and new versions are also released along with new profiles. The place to check for these updates is AI Central, the home of every AI you could ever want for Total Annihilation.  Filled with reviews, extra AI units and the widest and most up to date selection of AI's anywhere.  At AI Central the machine rules supreme.

Quell(er) TA, designed for standard Total Annihilation, a challenge in skirmish mode, it will also make campaigns a lot harder to win.

Quell(er) CC, a highly skilled CC player, making full use of all the extra units provided by the expansion pack Core Contingency.

Quell(er) UH, designed for the TA balancing MOD UberHack.  This AI understands all the changes and uses them to its advantage.

Queller SWTA, playing *the* Star Wars MOD for Total Annihilation.  You'll be overrun by Storm Troopers faster than you can say "May the force be with you".

Queller FB, for the game type Flea Bowl.  Have fun tackling thousands upon thousands of Fleas, and find out just how deadly they can be.

Queller TAK, made for standard TAK.  It will expand rapidly, level up wisely, and summon hordes of creatures hungry for blood.

Queller CUT, designed around the TAK Crusades balance, it focuses on what it wishes to do and makes sure it has the best units to do it with.
