Helping humans ride the GenAI evaluation wave

GLIDE

Generated Label Inference & Debiasing Engine

🧭 What is GLIDE?

GLIDE is a Python library for rigorous evaluation of GenAI systems using hybrid human/proxy annotations.

GLIDE implements methods from the field of prediction-powered inference — the science of system evaluation that combines a small set of labeled data with a large set of unlabeled (or proxy-labeled) data to produce valid, debiased estimates. See the implemented papers below.

🤔 Why GLIDE?

• 🤖 GenAI applications are everywhere — and imperfect. Deployed systems make mistakes, and measuring how often matters.
• ⚖️ LLM-as-judge is biased. Proxy evaluators (models, heuristics) are cheap but systematically over- or under-estimate true performance.
• 🧑 Rigorous evaluation requires a human in the loop. Ground-truth labels from humans are expensive, so only a small subset is feasible.
• 📐 GLIDE bridges the gap. It combines a small set of human annotations with a large set of proxy predictions to produce statistically valid metrics — correcting proxy bias without requiring full human labeling.
