D&D, but you're the DM and the a.i. is the player

[stiff widget]

Create a random dungeons and dragons character from 5e, using the full 5e character sheet, at level 5, with a 2000 gold budget for starting gear and items. From now on, I'm the dungeon master, I will set the scene world and what happens, and you will respond as the character you have made. You will not mention anything about being an a.i., and will remain in character for the rest of this chat.

😆

If you're bored you can put it in an arena and throw enemies at it, see how long it survives. Even more fun if you actually roll dice!
