Decision brief

uqlm offers specialized Python capabilities for quantifying uncertainty to improve confidence in language model outputs and reduce hallucinations.

Good fit when

  • When precise estimation of confidence scores is needed to ensure reliability in language model predictions.
  • For developers looking to enhance the safety and trustworthiness of their text generation systems by actively mitigating hallucination.

Avoid when

  • If working exclusively with non-language-based machine learning models, as uqlm focuses on text outputs from LLMs.
  • When simple plug-and-play performance metrics suffice; uqlm requires a more intricate setup for uncertainty quantification and confidence estimation.
