Models in Neptune

With Neptune runs, you can log, store, and organize your model metadata.

Log model metadata

To log the model metadata, use the run object. Depending on your setup, you can separate the model and training metadata by creating multiple runs or log everything together.

For an example, see Log model metadata.

Organize and compare model metadata

Runs come with rich comparison and visualization support. Use the Neptune app to:

• Organize your metadata with tags and grouping.
• View and compare your metadata with custom views, dashboards, and reports.
