Exclude or restrict models

You can exclude or restrict large language models (LLMs) to determine which models are available for Glean Assistant and Glean Agents, and who can use them.

When you exclude a model:

• The model becomes unavailable for selection in the agent builder, Glean Assistant, or both, depending on your configuration.
• Any agents or steps within an agent that were using the excluded model automatically switch to the default model.

Exclude models based on your organization's key type

Glean supports two types of keys: Glean Universal Model Key and Customer Key (BYOK). Depending on the type of key your organization uses, the steps to exclude models and what you can exclude are different.

For both key types, you can exclude individual models with separate controls for Assistant and Agents.

Glean Universal Model Key

You can turn off individual models and control whether they're available for Assistant, Agents, or across Glean.

To block a model across Glean:

1. Go to Admin console → Models.
2. On the Models page, use the search bar, capability filter, or scroll to find the model you want to block.
3. For the model you want to block, toggle the model off.
4. Click Save to apply your changes. This blocks the model across Glean.

Customer Key (BYOK)

If your organization uses a Customer Key (BYOK), here's how to block models so that your Glean doesn't use them:

1. Go to Admin console → Models.
2. Click Add LLM.
3. Select a LLM hosting provider.
4. In the Select all models that can be used in agents section, clear the checkbox next to the model you want to exclude.
5. Validate the connection.
6. Click Save. This blocks the model across Glean.

Block a model for Assistant or agents only

These blocklists work the same way for both key types. Blocking a model here affects only the surface you choose and is independent of whether the model is available across Glean.

To block a model for Assistant only:

1. Go to Admin console → Assistant → Settings.
2. Navigate to the Blocked models in assistant section, then click Manage the blocklist.
3. Search for models to add or remove from the blocklist.
4. Click Save to apply your changes. This blocks the model for Assistant only.

To block a model for Agents only:

1. Go to Admin console → Agents → Setup.
2. Navigate to the Blocked models in agents section, then click Manage the blocklist.
3. Search for models to add or remove from the blocklist.
4. Click Save to apply your changes. This blocks the model for Agents only.

Hide all premium models from model pickers

If your organization uses a Glean Universal Model Key, you can remove all premium models from the model pickers in Glean Assistant and the agent builder. This may help your organization save costs related to using premium models.

To view a list of premium models, see the Premium tier under Supported models in LLMs.

tip

Premium models have a $ Premium tag next to their names. This tag helps you identify premium models that incur higher costs so you can be mindful about which models you exclude.

Here are the steps to hide all premium models from the model pickers:

1. Go to Admin console → Models.
2. Click Advanced settings.
3. Toggle off the Show premium models in model pickers switch.

This immediately hides premium models from Assistant model choice and the agent builder. Users can no longer manually select a premium model in those model pickers, and any premium models Glean launches in the future are hidden from the pickers as well.

Toggle on the Show premium models in model pickers switch to show premium models in the pickers again.

important

This toggle only controls the model pickers in Assistant model choice and the agent builder. It does not block premium models everywhere in Glean. Automatic model selection (auto mode) can still choose a premium model for certain use cases, such as artifact generation.

To turn off a premium model completely across Glean, go to the Models page and exclude that specific model by toggling off its status. See Glean Universal Model Key for the steps.

Restrict model access by department

You can restrict any model to one or more departments so that only members of those departments can use it. This works for both Glean Universal Model Key and Customer Key deployments and applies wherever the model is used, including Glean Assistant and Glean Agents.

By default, Glean doesn't restrict models by department. If you don't select any departments for a model, everyone can use it. Department restrictions layer on top of the existing model controls — you still have to turn the model on (Glean Universal Model Key) or configure it (Customer Key) before the restriction takes effect.

Glean determines department membership from your synced people data. To learn how to populate the Department field for your users, see Sync people data.

To restrict a model to specific departments:

Glean Universal Model Key

1. Go to Admin console → Models.
2. Make sure the model is turned on.
3. In the Departments column for that model, open the selector and choose one or more departments. Leave the selector empty to keep the model available to everyone.
4. Click Save to apply your changes.

Customer Key (BYOK)

1. Go to Admin console → Models.
2. Click Add LLM, select the hosting provider, and continue to the model selection step.
3. Make sure the model is selected.
4. In the Departments column for that model, open the selector and choose one or more departments. Leave the selector empty to keep the model available to everyone.
5. Click Save to apply your changes.

The Departments column shows All departments when a model isn't restricted, or a count of allowed departments otherwise. Hover the count to see the full list.
