# Bring your own model key
> Add, replace, or revoke an OpenRouter key on the Model Provider tab so your agents' model calls run through your own OpenRouter account.

At the end of this page, your organization's model calls run through your own OpenRouter key. You also know how to read the key card, replace the key, revoke it, and act on a key failure.
This capability needs the **{planNames[props_0.plan] ?? props_0.plan}** plan or higher.
## Before you start
Before you start, sign in to the dashboard and select the organization you want to work in.
* You need the Admin role on a Premium or Enterprise plan. Other members do not see the **Integrations** page, and Free organizations do not see the **Model Provider** tab.
* Have an OpenRouter API key ready. Keys start with `sk-or-`. You create them on the OpenRouter keys page, which the add dialog links to.
* The key is used for the model calls of your agents' AI Agent gambits. See [AI Agent gambit](/docs/guides/building/gambits/ai-agent) for where an agent picks its model.
## Open the Model Provider tab
Open **Settings**, select **Integrations**, then select the **Model Provider** tab. The **Integrations** page has three tabs: **API Keys**, **Identity Verification**, and **Model Provider**.
Before a key exists, the tab shows one **OpenRouter** card. The card says the key unlocks any model on OpenRouter, is encrypted at rest, and is decrypted only at request time. Below the text sits a single **Add OpenRouter Key** button.
## Add your key
The **Add OpenRouter API Key** dialog opens.
The **Label (optional)** field names the key on the card, for example **Production**.
The field hides the key. Select the eye icon to show or hide it while you check it.
The checkbox reads **I understand TARS will use this key for all model calls in this org.**
The button reads **Validating…** while Tars checks the key with OpenRouter. On success a toast reads **OpenRouter key saved (…1234)**.
**Validate & Save** stays disabled until the key field has a value and the checkbox is ticked. The dialog says **Validated against OpenRouter before saving**, and that is the whole rule. A key that does not start with `sk-or-`, or that OpenRouter rejects, is not saved and the dialog shows the error. If OpenRouter cannot be reached, nothing is saved either, so try again later.
Your organization holds one OpenRouter key at a time. Saving a key when one already exists replaces it.
## Read the key card
Once a key is saved, the **OpenRouter** card shows an **Active** badge and a one-row table.
| Column | What it shows |
| ------------- | --------------------------------------------------------------------------------------------------- |
| **Key** | The masked key, for example `sk-or-…1234`. Only the last four characters are ever shown again. |
| **Label** | The label you entered, or a dash if you left it empty. |
| **Added** | The date the key was saved and the name of the member who saved it. |
| **Last used** | The date and time of the most recent model call made with the key, or a dash before the first call. |
Below the table sit two buttons, **Replace Key** and **Revoke**.
## Replace the key
Select **Replace Key** to rotate to a new key. The **Replace OpenRouter Key** dialog has the same fields, checkbox, and **Validate & Save** button as the add dialog. The new key is validated the same way, and on success it takes over immediately while the old key is discarded. There is no gap in which model calls fail, so rotate whenever your OpenRouter account requires it.
## Revoke the key
Revoking is immediate. Agents whose AI Agent gambits use an OpenRouter-only model show an error on their next turn until you add a key again or change the model.
Select **Revoke** to open the confirmation dialog, which is titled **Revoke OpenRouter key?** and repeats that warning. Select **Revoke key** to confirm. A toast reads **OpenRouter key revoked**, and the tab returns to the empty **OpenRouter** card. Model calls go back to the Tars key.
## When the key fails
If a recent model call failed because OpenRouter rejected your key, a red alert appears above the card. It reads **Your OpenRouter key returned an error (HTTP\_401) on the last request**, with the code OpenRouter returned. A second line reads **Model calls routed through your key error out until it is updated.**
The alert has two buttons:
* **Update Key** opens the **Replace OpenRouter Key** dialog.
* **Revoke Key** opens the **Revoke OpenRouter key?** confirmation.
The alert clears on its own once the failure is no longer recent. Fix the key first, or agents keep failing on every model call. Authentication failures, key additions, and key removals are also recorded in the audit log. See [Search and export the audit log](/docs/guides/security/audit-log).
## What changes when a key is active
* Every model call from your agents' AI Agent gambits, in the builder preview and in live conversations, is sent to OpenRouter with your key. OpenRouter bills those calls to your account. Your Tars plan and conversation usage do not change.
* In the builder, the model picker in the **Model** region shows a **BYOK · OpenRouter** banner with the last four characters of the key. The banner also has a **Manage** link back to the **Model Provider** tab. When a model outside the curated list is selected, the picker also shows a small **BYOK** badge next to the model name.
* The key does not change which models the picker offers. Premium and Enterprise plans already offer the full catalog. See [Plans overview](/docs/get-started/plans-overview).
* The key is stored encrypted and is decrypted only for the request being made. It is never shown again after you save it, only its last four characters. See [How Tars protects files, data, and identity](/docs/guides/security/data-protection).
## Verify
Open an agent whose AI Agent gambit uses a model from the catalog and send it a message in the builder preview. Return to the **Model Provider** tab. The **Last used** column now shows the time of that call.
