What is GLIDE?

GLIDE (Generated Label Inference & Debiasing Engine) is a Python library for rigorous evaluation of GenAI systems.

  • LLM judges are biased. Proxy evaluators systematically over- or under-estimate true performance.
  • Human annotation is expensive. Full labeling at scale is rarely feasible.
  • GLIDE bridges the gap. Thanks to prediction-powered inference, it combines both to produce valid, unbiased performance estimates.
Key features
  • Unbiased performance and risk estimates
  • Smart annotation budget allocation to minimise human labeling
  • Guaranteed confidence intervals regardless of proxy quality
  • Works for any metric, any AI system, any unstructured output requiring annotation
