Hikaru bot is not the real Hikaru Nakamura but a bot with the name Hikaru.
On Chessmaster there are bots named with name from human Gms like Christiansen but the bot named Christiansen doesn't play at all like the real Christiansen and same for the bot named Leko which is much less efficient than the real Leko.
On chess.com bots I beat the bot with the name GothamChess as well as Ahmed i.e a bot that won against Levy https://youtu.be/-ZVbDR3sRRo The Advanced Chess Bots Are Terrifying but against the real Levy Rozman I'd probably never have managed to win but the bot bearing Ahmed's name can beat him even if he's not as strong as Levy in the long run.
