LLM agent's critic shows extreme non-determinism, but code-based safety measures ensure stability

By PulseAugur Editorial · [1 sources] ·

An LLM agent's internal critic exhibited extreme non-determinism, producing different outputs on identical inputs across multiple trials. This instability was concerning because the agent's safety relied on its consistency. However, the system's overall safety was maintained because critical safety functions were moved out of the LLM critic and into deterministic code, such as structural under-claim checks and a severity taxonomy allowlist. AI

IMPACT Highlights the critical need for deterministic code-based safety measures in LLM agents, as model consistency alone is insufficient.

    My LLM Critic Disagreed With Itself on Every Trial. The Safe Part Was the Code I Didn’t Trust It to Touch.
