Every LLM Eval Library Has the Same Bug: Stochastic Judges Used as Deterministic Oracles

📰 Dev.to · Gabriel Anhaia

Learn how stochastic judges in LLM eval libraries can lead to noisy results and why it matters for accurate model evaluation

intermediate Published 29 Apr 2026
Action Steps
  1. Identify stochastic judges in your LLM eval library
  2. Run multiple iterations of the judge to estimate the variance of the results
  3. Use techniques like Monte Carlo sampling to account for the stochastic nature of the judges
  4. Implement deterministic oracles or use alternative evaluation methods to reduce noise
  5. Compare results from different evaluation methods to ensure accuracy
