When you first start the game, you're given a randomly selected AI named "CPU". To have a personal AI as a partner, go to Terminal and select AI Management.
You'll be presented with 3 options, from the top:
AI Set
New AI Creation
AI Deletion
Begin by selecting the 2nd option, which prompts you with the VR select menu. You'll return back to the 3 options. Now select the 1st option to setup your AI. You'll be presented with 3 new options:
Select AI
Remove AI
Edit AI
Select AI- A page listing of available AI you've created. Pick the AI you want, then exit to the main menu to let the system save and assign your AI partner.
Remove AI- This option doesn't delete your AI, but simply remove the AI from your partner slot so it defaults back to "CPU". Exit to the main menu once you're done.
Edit AI- You can change the properties of your AI here:
Attributes:
Friendship: 0= Lonewolf AI, 10=Performs Rescue Dash when needed.
Shoot (Offense): 10= Triggerhappy AI
Shoot (Defense): Projectile Evasion
Melee (Offense): 10= Aggressive CC
Melee (Defense): CC defense
Movement: 0= Less active, 10= Hyperactive
Below the attributes are options to:
Rename the AI
Assigning a different color
Confirm the edits.
You'll need to play Mission mode with the AI partner you wish to level up. You'll get AI points upon clearing a mission. SS rank usually nets you 3 points. You're given a maximum of 50 points to fill up the attributes, and there's no turning back after you've "Confirm your Edits", so be wise when spending your points

Hope this helps. Feel free to correct me if I got anything wrong
