Skip to main content
Prompts lists every prompt in your workspace, with its product, type, status and current version. Each prompt keeps a full history: every time you save a change to the prompt, model or settings, Nucleus adds a new version and keeps the ones before it, so you can compare them or go back. Use the search box and the product, type and status filters above the list to find a prompt, then select it to open it.

Before you start

Tenant Owners and Workspace Admins can create prompts, go back to an earlier version and turn a prompt off. Workspace Members can open, edit and try them. Every prompt is filed under a product and a type, which Tenant Owners and Workspace Admins set up in Nucleus settings.

Save a new version

The lower part of a prompt's editor, with Advanced configuration, the Commit message box, the release list and Save.
The Model list shows the models your workspace allows for Nucleus. Tenant Owners and Workspace Admins manage them in Studio settings, under AI Models.

You are back in the editor. Next, go back to an earlier version if the older one was better.
While comparing, press the up and down arrow keys, or J and K, to jump between changes.

Go back to an earlier version

Select any version in Version history to read it. Older versions are read-only. Tenant Owners and Workspace Admins can bring one back.
1

Find the version

In Version history, find the version you want back.
2

Revert

Select Revert on that version.
3

Confirm

Confirm that you want to revert.
Nucleus adds a new version with the older content and makes it current, so nothing in the history is lost. Next, release it.

Open the prompt

Select Prompts, then the prompt.
2

Deactivate it

Open the prompt

Select Prompts, then the prompt.
2

Activate it

Select Activate.
Next, check the health of your active prompts.

Troubleshooting

Change the prompt, the model or a setting, and enter a Commit message. Nucleus only saves a version that differs from the one before.
A new prompt has no evaluation yet, so it has not passed the quality check for staging. Write why it should start there, or choose Dev instead.
Another active prompt in your workspace has that name. Choose a different Prompt Name.
The name belongs to one of Studio’s built-in prompts. Choose a different Prompt Name.
Ask a Tenant Owner or Workspace Admin to add a type for that product in Nucleus settings.
Your workspace has no models allowed for Nucleus yet. Ask a Tenant Owner or Workspace Admin to allow one in Studio settings, under AI Models.
Only Tenant Owners and Workspace Admins can create prompts. Ask one of them to create it, then you can edit it.
