Co-op vs. AI is a game mode in League of Legends where a team of players take on a team of computer-controlled champions commonly known as bots. The size of the team is the same as in normal player versus player matches, but the variety of game modes has been reduced.

Co-op vs. AI It is available in Summoner's Rift and Twisted Treeline. There are three difficulties to choose from: Introduction (SR only), Beginner, and Intermediate. Players can queue alone or in groups, and they are combined in a similar way to normal games. However, players are ranked by level rather than their matchmaking ranking. The First Victory of the Day mission is available, and normal and ranked MMRs are not affected.
Co-op rewards against AI are slightly higher than custom games, but lower than normal or ranked matches. The current rules for Co-op vs AI rewards are:
- All Summoners can earn unlimited rewards of XP e IP per day in Co-op vs. AI. However, level 15+ summoners can only earn 75% of Co-op vs. normal AI rewards after 180 minutes.
- Co-op vs. AI does not award champion mastery points.
- The following modifiers apply based on summoner level and bot's difficulty setting. These percentages represent the amount of the standard reward that is received:
There is a group of 68 champions that bots can be chosen from. They are as follows, listed in categories according to five main roles: 
- Please note: Xerath y Vayne bots are not available in custom games.
- Please note: Sona bot was removed after its remake.
- Nota: Aatrox, Anivia, Azir, Bard, Camille, Diana, Draven, Ekko, Elise, Evelynn, Fiora, Gnar, Gragas, Hecarim, Illaoi, Janna, Jayce, Kalista, Karma, Kassadin, Kennen, Kha'Zix, Kindred, Kled, LeBlanc, Lee Sin, Lissandra, Lulu, Mordekaiser, Nautilus, Poppy, Rek'Sai, Rengar, Riven, Rumble, Sejuani, Shaco, Singed, Skarner, Syndra, Talon, Thresh, Tryndamere, Twisted Fate, Twitch, Urgot, Varus, Vel'Koz, Vi, Viktor, Volibear, Zac, and Zed bot are yet to be added.
Bots have different behaviors and advantages depending on the selected difficulty. Some behaviors are standard, regardless of difficulty selected. Most notably, bots will not seal or chase creep upgrades, although bots on the Twisted Treeline map will actively acquire pad and altar upgrades located around the map. The other universal behavior is a faster revive time if killed. Bots will occasionally chat at the beginning and end of games.
- The bots wait a few minutes before joining the battle.
- The bots only buy boots and dorans items.
- Bots react much slower when it comes to escaping due to low health or skill usage.
- The bot pool has less variation, as the game is based on a smaller selection of champions.
- The bots use less advanced tactics and are not launched as effectively.
- The bots do not receive any rune or domain bonuses, or some kind of equivalent.
- The bots don't use any summoner spells, despite equipping 2.
- Bots don't need a line of sight to target their abilities. For example, if a nearby enemy bot or minion sees you enter the bushes, the enemy bots can target that bush directly for several seconds (as if it were protected). This differs from human opponents who would have to face bush control (if unprotected) to use direct target abilities.
- The bots will use more advanced tactics. This includes switching champions on lanes, attempting to gank often, or more rarely attempting to push a lane with three champions in the first ten minutes.
- Bots will keep earning items even if they were hungry for gold in a lane. This suggests that they earn items based on level or have increased gold over time.
- Bots do not have masteries.
- The bots will wear alternate champion skins, which can cause confusion.
- Bots will actively use summoner spells like ignite, heal, drain, and ghosts, but will rarely teleport.
Co-op vs. AI was first announced on the League of Legends website on January 20, 2011, as a new game mode intended to demonstrate a more difficult challenge and training method for players rather than just the bots available through of the custom game option.
A fight was announced on February 4 showing a fight between some of the new bots against mid-level Riot employees that will take place on February 9. This battle was streamed via Own3d, and resulted in a close (and incomplete) victory for the Bots.
It was meant to be released the week after patch 184.108.40.206, but it was delayed because European servers weren't ready to take on the increased stress that the gameplay could cause.
It was finally released on Thursday, March 10. It supported two difficulty settings, Beginner and Intermediate, and a group of 12 bots available only in Summoner's Rift.
