The main differences are in usage limits, features, and support levels:

Comet Free: Ideal for individuals and small projects. Includes core experiment tracking features with fair usage limits, 100GB data storage, and community support.

Comet Pro: Perfect for growing teams. Offers increased limits (1,500 training hours, 500GB storage), supports up to 10 users, and provides email support. Priced at $39 per user/month.

What is a training hour?

A training hour represents 60 minutes of active model training time recorded in Comet. If your model takes 8 hours to train, you’ve used 8 training hours. This time is based on the time between starting and stopping an Experiment.
