Curate better data,
build better models
with FiftyOne

Voxel51 is the company behind FiftyOne, the open source toolkit for building high-quality datasets and computer vision models. Need collaborative features? Check out FiftyOne Teams.

Trusted by tens of thousands of engineers and their forward-looking companies

We use FiftyOne Teams to organize, select, display, and share our data which has led to better collaboration with and understanding of our large volume of data. FiftyOne Teams enables us to gain insights such as identifying and understanding data problems early, hypothesis validation, and dataset management overall. This has led to better solution engineering and better testing for the products and services we deliver to our customers.

With FiftyOne, you can...

Visualize your data

Explore, search, and slice your datasets. Quickly find the samples and labels that match your criteria.

Curate high quality datasets

Use FiftyOne’s tight integrations with public datasets like COCO, Open Images, and ActivityNet, or create your own datasets from scratch.

Train better models

Data quality is a key limiting factor on model performance. Use FiftyOne to identify, visualize, and correct your model’s failure modes.

Find mistakes

Annotation mistakes lead to bad models, but finding mistakes by hand isn’t scalable. FiftyOne helps automatically find and correct label mistakes so you can curate higher quality datasets.

Use the Brain

Aggregate performance metrics and manual debugging don’t scale. Use the FiftyOne Brain to identify edge cases, mine new samples for training, and much more.

Get to production faster

Data scientists spend up to 65% of their time wrangling and evaluating data. With FiftyOne, build data-centric pipelines that surface the high quality data that production-ready models need.
