# Language Models

> Configure the OpenModels catalog, choose available language models, and set a deployment default.

Language Models is where Admins choose the OpenModels catalog entries that the deployment can use. It supports a multi-model setup: make more than one approved model available and select a sensible default for ordinary requests.

## Before you begin

Confirm that the credential required by each service is present and current. Credentials provide secure service access; this page controls which catalog models the deployment selects from that access.

## Configure catalog models

Open **Models & Capabilities**, then open **Language Models**. Review the OpenModels catalog, enable the models that fit the deployment's requirements, and associate each selection with a working credential where needed. Keep the enabled set understandable so Curators can make intentional model choices.

## Choose the default model

Set a default model for requests that do not specify one. Consider capability, quality, latency, cost, and the model's availability for the deployment. A default does not prevent approved Agents or workflows from using another enabled model when their configuration requires it.

## Verify availability

After saving, confirm that the selected models appear where authorized people configure or use them. Test a representative request, then revisit the credential and catalog selection if the model is unavailable or cannot complete the expected task.
