# Configure the Small Model

> Select the lightweight model Cake Agents uses for background tasks like session title generation.

The small model is the lightweight model Cake Agents uses for background tasks that do not require the default model's full capabilities. The most common use is auto-generating a session's title from its first message. Picking a fast, low-cost model here keeps those background tasks quick and cheap without affecting the model that runs your sessions.

## Prerequisites

* You are signed in as an administrator.
* At least one provider is configured with at least one model. See [Configure Model Providers](/admin/model-providers).

## Configure the Small Model

1. Sign in to Cake Agents as an administrator.
2. Open `Settings → Organization → General`.
3. Under `Small model`, pick a model from the dropdown.
4. The selection saves automatically.

The small model is a required setting and is shared across the whole organization. Any model exposed by your configured providers is a valid choice.

## How Cake Uses the Small Model

When Cake builds the OpenCode configuration for a session, it passes the selected model as `small_model`. OpenCode uses it for internal, lightweight calls such as generating a session title. Your main conversation continues to use the [Default model](/admin/model-providers) or whichever model the user picked for that session.

## Recommendations

* Choose a small, fast, inexpensive model from the same provider you already use for the default model.
* Do not point the small model at a large reasoning model. Session titles and other background tasks do not benefit from it, and every new session pays the cost.
* If you retire a model or change providers, update the small model selection so it keeps pointing at a model your providers still expose.
