Manage Any ML or LLM Lifecycle, From Training Through Production

Manage Any ML or LLM Lifecycle, From Training Through Production

Automatically track all your prompt engineering work. Run automated evaluations on your LLM responses to optimize your applications before and after they hit production.

Opik – Open Source LLM Evaluation

Log all your machine learning iteration to a single system of record. Make it easy to reproduce a previous experiment and compare the performances of training runs.

Comet Experiment Management

Track data drift on your input and output features after your model is deployed to production. Set customized alerts to capture model performance degradation in real time.

Model Production Monitoring

Create a centralized repository of all your model versions with immediate access to how they were trained. Promote models to downstream production systems with webhooks

Comet Model Registry

Know which exact dataset version a model was trained on for auditing and governance purposes. Leverage remote pointers to reference data already stored in the cloud.

Easy Integration

Add just a few lines of code to your notebook or script and automatically start tracking LLM traces, code, hyperparameters, metrics, model predictions, and more.
