Below is a comparison of features. Please note that those AIs which aren't meant for running a transport company (such as Idle, IdleMore, etc.) are discussed below.
|AI||Trains||Road vehicles||Aircraft||Ships||Passengers/mail||Freight||Save/load compatibility||NewGRF compatibility|
|Goes bankrupt frequently when NuTracks is in use|
|Will build cars in towns if a town cars NewGRF is present|
|No NewGRF road vehicle support|
|NARS is the preferred trainset, works with the 2cc TrainSet and the default trainset|
|Problem with Japanese trainset.|
|Can only use non-articulated buses|
|No support for NewGRF railway track sets|
|No support for industry replacement sets|
* Trams are also included
² Might have unfinished routes
** Makes a few moneymaker train routes when starting but after that doesn't use trains
There have been some tests on the forums comparing the performance of the AIs. These threads include graphs and other screenshots, savegames are available for download.

There has also been a test on the CPU usage of particular AIs in May 2010:
See also AI:Test AIs - attempt to measure performance of various AIs.
- Beginner Tutorial - Ship AI - A special Ship AI for the Beginner Tutorial, it is meant to be used together with the game script. It only visible to AI/game script developers.
- CityConnecter - An AI which connects nearby towns with roads.
- Idle - An AI that does nothing, keeping minimal permissible balance. Idle can be used for running multiple companies in a singleplayer game, using the company switching cheat.
- IdleMore - It is a fork of Idle which does even less work. Bank balance management is configurable, and it doesn't rename its company upon loading a savegame.
- Orders Assistant AI - This AI does not play on its own. It manages routes for a player which has joined its company.
- StreetTrafic1 - It is a fork of TownCars, which runs cars in towns for eye-candy. It needs a car NewGRF to be present (like Generic Cars).
- TownCars - An AI which runs cars in towns for eye-candy. It needs a car NewGRF to be present (like Generic Cars).
- TREE - An eyecandy AI which plants trees and lets the user control how many it plants (and where) instead of the general explosion of trees normally encountered in OpenTTD games. It is meant to be used with the tree growth setting disabled.
- TutorialAI - An AI which acts as an in-game tutorial, introducing new players into playing OpenTTD. It has now been replaced by Beginner Tutorial which uses a Game Script for the tutorial.
- WmDOT - An AI which connects towns with roads, without running any vehicles on them. WmDOT can be used to have a pre-built road network between towns. It uses ships to make some profit.
