What Comet does
Comet manages experiment tracking, datasets, artifacts, model registry, visual comparison, optimization, and production monitoring.
Comet creates a shared record of ML work across notebooks, logs, and storage. SDK integrations capture experiments while its registry and monitoring connect development to governance.
Free supports one platform user. Pro is $19 per user monthly for up to ten users with 1,500 training hours. Enterprise is custom and adds flexible deployment, monitoring, service accounts, SSO, support, and compliance. Confirm storage and overages.
Automatic logging may capture code, Git data, environments, file paths, or artifacts unexpectedly. Configure it deliberately, secure API keys, prohibit secrets and regulated fields, and review project visibility. Tracking improves but cannot guarantee reproduction.
How Comet works
Training code uses the Comet SDK to log selected parameters, metrics, code metadata, artifacts, datasets, and models into organizations, workspaces, projects, and experiments. The application compares runs, creates visualizations, tracks versions, and registers candidates. Enterprise monitoring ingests production signals. Data scientists review evidence and owners decide promotion or retraining.

Design access
Map workspaces, projects, accounts, privacy, roles, and environments.
Instrument one pipeline
Secure the key, disable unwanted logging, and use stable identifiers.
Create registry rules
Define comparisons, baselines, model cards, gates, aliases, and rollback.
Validate operations
Test rate limits, large artifacts, alerts, deletion, export, and ownership.
Comet FAQs
Is there a free plan?
Yes. The current Free plan supports one platform user.
How much is Pro?
The official page lists $19 per user monthly for up to ten users.
What can it log?
Metrics, parameters, code and system metadata, artifacts, datasets, visualizations, and models.
Does Comet deploy models?
It manages registry workflows and monitoring; serving runs in the selected environment.
Does tracking ensure reproduction?
No. Data, code, dependencies, hardware, randomness, and external services also matter.
