Update artifacts

Pass desired values to update the description, metadata, and alias of an artifact. Call the save() method to update the artifact on the W&B servers. You can update an artifact during a W&B Run or outside of a Run.

Use the W&B Public API (wandb.Api) to update an artifact outside of a run. Use the Artifact API (wandb.Artifact) to update an artifact during a run.


You can not update the alias of artifact that is linked to a model in Model Registry.

The proceeding code example demonstrates how to update the description of an artifact using the wandb.Artifact API:

import wandb

run = wandb.init(project="<example>", job_type="<job-type>")
artifact = run.use_artifact("<artifact-name>:<alias>")
artifact.description = "<description>"
