Here's the short:

Human identities are non-deterministic (behavior changes based on context) and often authorized through RBAC, ABAC, or other identity governance controls.
Bot identities are machine accounts that exhibit deterministic behavior. They operate under pre-defined permissions, which means specific inputs result in expected outputs every time.
Meanwhile, AI agents are non-deterministic, autonomous systems. They adapt, negotiate, and choose actions based on context. They’re also often ephemeral (short-lived) and can make choices you didn’t explicitly program them to make.

For example, they can probe their environment and grant themselves higher privileges if not properly constrained.

And if you have multiple agents forming ad-hoc workflows, the potential for misuse or unintended actions rises.

And therein lies the problem. Because of their non-deterministic behavior (read “unpredictability”), AI agents can’t just be classified as bot or machine identities.
