# How can I delete multiple runs in bulk instead of one at a time?

From the **Runs** tab in your Workspace, select the checkbox next to each run to delete, then click **Delete**.

To filter runs by a condition rather than selecting them manually, use the [public API](/models/ref/python/public-api/api) to delete multiple runs in a single operation. Replace `"entity"` and "project" with your entity and project names, and replace `[CONDITION]` with a Python expression that evaluates to `True` for runs you want to delete:

```python theme={null}
import wandb

api = wandb.Api()
runs = api.runs("entity/project")
for run in runs:
    if [CONDITION]:
        run.delete()
```

For example, if you want to delete runs that were created before a specific date:

```python theme={null}
import wandb
from datetime import datetime

api = wandb.Api()

entity = "wandb"
project = "project"
cutoff = "2024-01-01T00:00:00Z"  # delete runs created before this UTC timestamp

runs = api.runs(
    path=f"{entity}/{project}",
    filters={"createdAt": {"$lt": cutoff}},
    order="+created_at",
)

# Dry run first
runs_to_delete = list(runs)
print(f"Found {len(runs_to_delete)} runs to delete:")
for run in runs_to_delete:
    print(run.id, run.name, run.created_at)

confirm = input("Type DELETE to permanently delete these runs: ")
if confirm == "DELETE":
    for run in runs_to_delete:
        print(f"Deleting {run.path}")
        run.delete()  # or run.delete(delete_artifacts=True)
```
