Questions & Answers
What are the differences between Comet Free, Comet Pro, and Comet Enterprise?
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.
Comet Enterprise: Designed for large organizations. Provides unlimited usage, advanced production monitoring features, flexible deployment options, SSO, dedicated support, and enterprise-grade platform capabilities.
All plans include essential features like experiment tracking and LLM evaluation. Enterprise exclusively offers advanced monitoring, custom metrics, and enhanced security features.
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.
Is there a free plan for academics?
Yes, Comet offers a free Pro plan for academic users. Researchers, students, and educators can access the full features of our Pro plan at no cost. To apply for the academic Pro plan, please sign up here and follow the instructions on the Academics page to verify your academic status.
