# Providers

> Add and edit LLM providers in Manage Models - Provider ID, display name, description, and Requires API Key (Vault)

Providers are the top-level grouping for models on **Manage Models** (`/costs?tab=models`). OpenLIT ships 14 built-in providers; you can add your own for self-hosted or niche APIs.

## Add a provider

<Steps>
  <Step title="Open Add Provider">
    In the Manage Models header, click the **+** control (tooltip: **Add Provider**).
  </Step>

  <Step title="Fill in the fields">
    * **Provider ID** - lowercase identifier (e.g. `my-provider`). Spaces become hyphens; other special characters are stripped. This must match what your SDK sends in `gen_ai.system`.
    * **Display Name** - label shown in the UI.
    * **Description** - optional.
    * **Requires API Key (Vault)** - toggle on if callers need a Vault secret for this provider.
  </Step>

  <Step title="Save">
    Click **Add Provider**. The provider appears in the left sidebar.
  </Step>
</Steps>

## Edit a provider

Hover a provider in the sidebar and use the edit control to open **Edit Provider**. You can change display name, description, and the Vault requirement. **Provider ID cannot be changed** after creation.

## Delete a provider

There is no delete button in the Manage Models UI today. To remove a provider and all of its models, use the [Providers API](/latest/openlit/developer-resources/api-reference/endpoint/manage-models/providers) `DELETE` operation.
