How it Works
Cleanlab Open-Source
Our Cleanlab Open-Source package is the most popular software framework for practicing Data-Centric AI today. Most of our open-source functionality comes from novel data quality algorithms developed by our team and published in research papers for transparency and scientific rigor.
What Cleanlab Open-Source offers:
  • Limited Python API Access: Implement the Cleanlab open-source library for your existing pipelines and models to detect issues in your data.
  • Support for Popular Data Types: Works with image, text, tabular, audio, and PDF data formats.
Upgrade to Cleanlab Studio for advanced automated data quality improvements and analysis, seamless integration into your enterprise-level data storage and cloud platforms, instant AutoML/deployment scaled to massive datasets, full Python API access and more. Request a demo from our engineers or sign up for a free trial.

Loved by Data Scientist and ML Engineers
Cleanlab is being used by individuals and enterprises across industries to turn unreliable data into reliable models, and find and fix errors for LLMs and the modern AI stack.

“Recently took part in a new kind of ML competition based on Andrew Ng’s idea of shifting focus from model-centric to data-centric AI. Found cleanlab, a useful package in supporting this data-centric movement. It is based on the field of confident learning and helps to detect and learn in the presence of noisy real world labels.”

“I used an open-sourced library, cleanlab, to remove low-quality labels on an image dataset. The [ResNet] model trained on the dataset without low-quality data gained 4 percentage points of accuracy compared to the baseline model (trained on all data).”

“I’m just starting to get the hand of this and read on how it works. But right now from the first results it looks like pure black magic... So thank you for this!!”

“We’re looking into making Cleanlab a standard processing step whenever we get labels.”

“Improving your training data is more important that using the latest ‘state-of-the-art’ model. Here’s a very simple trick: use cleanlab, a Python package for machine learning with noisy labels and finding mislabeled data.”
