Pinocchio: Fast Uncertainty Estimates for Black-Box Language Models
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- Pinocchio is an external calibrator that estimates uncertainty in responses from closed-source language model APIs without requiring access to internal model states.
- Why it matters
- Engineers deploying black-box LLM APIs in high-stakes applications need confidence scores for model outputs to make safer deployment decisions.
- Watch out
- The method was trained on seven LLMs and tested on thirteen unseen models; generalization beyond this scope and real-world performance remain to be validated.
