Abstract

Run the same task through the same LLM twice, and you may get two materially different answers. This behavior is often dismissed as the stochastic nature of LLMs, but it creates a serious product risk. In high-stakes domains such as cybersecurity, a model that alternates between classifying the same activity as malicious and benign can undermine customer trust and lead to costly decisions if a real cyber threat is missed.

These “flip-flops” tend to cluster in the gray zone near a decision boundary, where evidence is incomplete, policies are ambiguous, and even human experts may disagree. They also reveal where a system is most vulnerable: adversarial techniques, from malware evasion to LLM jailbreaks, deliberately search for uncertain boundaries they can cross.

Instead of treating every flip-flop as noise, we can use disagreement as a hill-climbing signal. Each inconsistency helps identify the next high-value improvement: clarify a policy, correct a label, add relevant knowledge or precedent, or request focused human feedback. Repeating important evaluations also provides a more representative picture of production behavior than a single successful run.

In this session, you’ll learn a practical workflow that combines active learning, semantic memory for domain knowledge and business policies, and episodic memory for similar historical cases. Together, these techniques create a continuous improvement loop that makes agents more consistent, secure, and aligned with customer-specific decision without relying solely on costly fine-tuning.

You’ll learn how to:

  • Measure flip-flops through repeated evaluation and identify reliability risks hidden by one-shot tests.
  • Find the gray zone and direct human attention toward the decisions where feedback has the greatest value.
  • Use disagreement as a hill-climbing signal to improve policies, labels, memory, and agent behavior.
  • Combine semantic and episodic memory to increase consistency without defaulting to retraining.
  • Build a continuous learning loop that improves quality while adapting to how customers make decisions.
