How-To: Stop Worker

This guide shows how to stop a model's worker in the Lattica Console or with the Python SDK. A stopped worker no longer uses credits.

Before you start

Runtime is billed

A running worker uses credits even when it's idle. Stop it when you've finished querying. See Monitor Usage to compare hours with queries. A worker is also stopped automatically when your credits run out.

Queries need a worker

Once the worker is stopped, the model can't process queries until you start a worker again.

Frees model changes

Changing a model's status, or a token's model, isn't possible while a worker is running on it. Stop the worker first.

Step 1 of 5:

Open Models

In the Console, select Models in the left menu.

Python SDK

Find the model's running worker with studio.workers.active, then stop it with studio.workers.stop.

stop_worker.py

import os

from lattica_studio import LatticaStudio

studio = LatticaStudio(os.environ["LATTICA_LICENSE_KEY"])
model = studio.models.get_by_name("DermAI Spotter")

for worker in studio.workers.active(model.id):
    stopped = studio.workers.stop(model_id=model.id, session_id=worker.session_id)
    print(f"Worker {stopped.session_id}: {stopped.status}")

Pass both model_id and session_id to stop one worker. If you pass only model_id, every worker of that model may be stopped. If you started the worker with studio.workers.running(..., stop_on_exit=True), it stops on its own when the block ends.
