While AI agents have shifted programming away from deterministic algorithms toward probabilistic LLMs, there remains concern that the lack of determinism makes an agentic solution inherently unreliable. The question comes down to this: Is non-determinism acceptable?
The answer depends on what the solution is for. For creative endeavours such as ideation or writing fiction, non-deterministic responses can be a strength. But I’m sure we can agree that software that relies on precise results, such as those used in finance or scientific research, cannot accept non-determinism.
