# AI settings

Workspace-wide defaults for every assistant: the system prompt, the default model, tests before publishing, and workspace memory.

## Where to find it

In the console's left-hand menu, choose **Studio › AI settings**. **Workspace settings** also links to it under **Module settings**.

This page holds the workspace's defaults. One assistant's own settings are on that assistant's page; see [Assistants](https://agentlab.cresclab.com/docs/en/studio/assistants.md).

## Assistant defaults

| Setting                                 | Description                                                                                                                               |
| --------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- |
| System prompt                           | Tone and ground rules every assistant in this workspace follows. Up to 10,000 characters.                                                 |
| Default model                           | Used when an assistant doesn't pick a model. See [Default model](https://agentlab.cresclab.com/docs/en/studio/ai-settings.md#default-model). |
| Require passing tests before publishing | When on, an assistant must pass a full test run before it can be published.                                                               |

Select **Save** when you're done. The three settings are saved together.

## Default model

The **Default model** menu has three kinds of choice:

- **Platform default** uses whatever model the platform currently defaults to.
- **Capability** offers **Fast**, **Balanced** or **Reasoning**. Pick one and Agent Lab chooses a suitable model within your plan. Only the levels your workspace can use are listed.
- **Specific model** pins the model you pick.

Models your plan doesn't include are still listed, marked **(not in your plan)**, and can't be chosen.

If the current default model has dropped out of your plan, the page tells you. You have to pick another before the page will save, even if you only changed the system prompt.

## System prompt history

Every save of the system prompt keeps a version. **System prompt history** lists them newest first, each labeled with its version number and when it was saved.

There's no one-click restore. To go back, copy an older version into **System prompt** above and select **Save**.

## Workspace memory

**Workspace memory** lists what assistants remember across the workspace. Each entry shows its kind (**Standing** or **Recollection**) and the date it was captured. Entries someone explicitly asked to keep carry an **Asked to remember** label.

- Click an entry to edit it, then select **Save**.
- If an entry is wrong, select **Forget this fact** to delete it.

## Who can change it

| Role   | Assistant defaults | System prompt history | Workspace memory |
| ------ | ------------------ | --------------------- | ---------------- |
| Owner  | Can change         | Can see               | Can change       |
| Admin  | View only          | Hidden                | Can change       |
| Member | View only          | Hidden                | Hidden           |

Anyone who can't change the defaults sees "Only the workspace owner can change these settings."

## Settings that live elsewhere

| To set                                            | Go to                                      |
| ------------------------------------------------- | ------------------------------------------ |
| Workspace time zone (the default for automations) | **Workspace settings › General**           |
| Approvals for tool calls, and business rules      | **Workspace settings › Policies**          |
| Monthly and six-hour token limits                 | **Workspace settings › AI spend & limits** |

The token limits also apply to [automations](https://agentlab.cresclab.com/docs/en/studio/automations.md). A routine that comes due after a limit is reached shows as **Skipped** for that run.
