Comet ML
MLOps platform for AI teams to track, compare, explain, and optimize machine learning models and training runs.
What is Comet ML?
MLOps Platform for Model Development
Comet ML is a comprehensive MLOps platform that enables AI and data science teams to track, compare, explain, and optimize machine learning models and training runs. It provides the experiment management infrastructure that makes ML development collaborative, reproducible, and iterative — capturing every training run's parameters, metrics, code versions, and artifacts for complete experimental traceability.
Experiment Tracking at Scale
Comet integrates with major ML frameworks through simple SDK instrumentation, automatically capturing metrics as models train. Its comparison tools make it easy to identify what changed between runs and why certain configurations perform better. The platform also supports model registry features, enabling teams to manage the full lifecycle from experimentation to production deployment.
- Automatic experiment tracking with all major ML frameworks
- Real-time training metrics visualization and comparison
- Model registry for versioning and managing production models
- Artifact management for datasets, checkpoints, and outputs
- Team collaboration with shared experiment views
For Data Science Teams
Data science teams at companies ranging from startups to Fortune 500 enterprises use Comet to bring order to the often chaotic process of ML experimentation. Rather than losing track of which experiment led to the best model, Comet maintains a complete, searchable history of every training run with all the information needed to reproduce or understand any result.
Key Features
Automatically captures metrics, parameters, and code for every training run.
Side-by-side comparison of any training runs to identify performance differences.
Version and manage ML models from experiment to production deployment.
Store and version datasets, checkpoints, and model outputs alongside experiments.
Share experiments, findings, and models across data science team members.
Who Uses Comet ML?
Data scientists track and compare experiments to find optimal model configurations.
Manage model versions and deployments through the model registry.
Share experimental findings and reproduce results across distributed ML teams.
Track model metrics over time to detect drift and degradation in production.
