Autolabel is a Python library to label, clean and enrich datasets with Large Language Models (LLMs).

🌟 (New!) Access RefuelLLM through Autolabel

You can access RefuelLLM, our recently announced LLM purpose built for data labeling, through Autolabel (Read more about it in this blog post). Refuel LLM is a Llama-v2-13b base model, instruction tuned on over 2500 unique (5.24B tokens) labeling tasks spanning categories such as classification, entity resolution, matching, reading comprehension and information extraction. You can experiment with the model in the playground here.

  • Autolabel data for NLP tasks such as classification, question-answering and named entity-recognition, entity matching and more.
  • Seamlessly use commercial and open source LLMs from providers such as OpenAI, Anthropic, HuggingFace, Google and more.
  • Leverage research-proven LLM techniques to boost label quality, such as few-shot learning and chain-of-thought prompting.
  • Confidence estimation and explanations out of the box for every single output label
  • Caching and state management to minimize costs and experimentation time

Getting Started

You can get started with Autolabel by simpling bringing the dataset you want to label, picking your favorite LLM and writing a few lines of code.
