An AI anticheat will not beat the established ones. What a custom plugin does better: server-specific checks, logging, punishments, staff alerts.
No, an AI generated anticheat will not compete with the established ones, which are the result of years of tuning against real cheat clients. What a custom plugin does very well instead: catch the behaviour that is abnormal on your server, log everything, apply punishments automatically and alert your staff live.
No, and that needs saying plainly. Those projects rest on years of tuning against cheat clients that keep changing, across every game version and every ping range. A generated plugin has none of that history. Run a maintained anticheat for movement and combat, and use a custom plugin for the rules that only apply to your server.
Two layers. The first is a proven anticheat for movement and combat. The second, the one you can generate, watches what is abnormal on your server: money earned too fast, items that appeared from nowhere, an impossible minigame score, blocks broken at an inhuman rate. Add logging and you end up with evidence instead of hunches.
It can catch the crudest cases, but this is exactly where false positives live: lag, elytra, knockback, potion effects. If you want to try anyway, run it in alert only mode with no automatic punishment, and watch who shows up over several days before you wire anything to a ban.
