Manage AI Notebooks

This page explains how to stop, start, and delete an AI Notebook, and how the notebook's status affects billing.

Notebook status lifecycle​

A notebook moves through the following states:

StatusWhat it means
Creating…The GPU instance is being provisioned. Wait 3–5 minutes.
RunningThe notebook is active. Billing is accumulating.
Starting…The notebook is starting up after a Stop/Start cycle. Wait 1–2 minutes.
StoppedThe notebook is inactive. Billing has stopped. Your persistent storage is retained.
FailedProvisioning failed. Click Re-Create to try again.
warning

Billing starts the moment the notebook reaches Running. It stops only when you explicitly stop the notebook — not when you close the browser or log out.

Stop a notebook​

Stopping a notebook releases the GPU instance and stops billing. Your persistent disk data is retained.

  1. On the notebook list, find the notebook with status Running.
  2. Click Stop.
  3. Confirm in the dialog.

The status changes to Stopped. Billing stops at this point.

note

Stopping a notebook terminates all running kernels. Save your work in JupyterLab before stopping.

Start a stopped notebook​

  1. On the notebook list, find the notebook with status Stopped.
  2. Click Start.

The status changes to Starting…, then to Running within 1–2 minutes. Billing resumes when the status reaches Running.

Re-create a failed notebook​

If a notebook reaches Failed status:

  1. On the notebook list, find the notebook showing Failed.
  2. Click Re-Create.

The portal attempts to provision a new GPU instance. The status returns to Creating….

If the notebook fails repeatedly, see Troubleshooting or contact your Workspace Admin.

Delete a notebook​

Deleting a notebook permanently removes the notebook and its persistent storage. This action cannot be undone.

  1. On the notebook list, click the Access button on the notebook you want to delete. This opens the notebook detail page.

  1. Click Delete in the top-right corner of the detail page.
  2. Read the confirmation — deleting stops all running kernels and removes all stored data.

  1. Click Delete to confirm.
warning

Deletion cannot be undone. Back up any files you need from JupyterLab before deleting.

Understanding billing for notebooks​

  • Billing starts when the notebook reaches Running.
  • Billing stops when you click Stop and the status changes to Stopped.
  • Storage cost continues while the notebook exists, even when stopped — persistent disk is billed at a lower rate than the GPU instance.
  • Deleting stops all charges including storage.

To check your Workspace's current credit usage, go to Billing in the Workspace sidebar.

Idle behavior and auto-shutdown​

AI Notebook automatically disconnects idle sessions to prevent unexpected charges.

TriggerIdle thresholdWhat happens
GPU Kernel idle30 minutes of no code executionKernel is automatically disconnected.
Lab Environment idle1 hour of no interaction (no typing, clicking, or tab switching)Lab is automatically deleted to free resources.
note

If the lab is deleted due to idleness, your saved files are still in persistent storage. Only unsaved work (in-memory variables, unsaved editor buffers) is lost. Save frequently.
