# Per-Chat Proxy Selection

> Assign different proxies to individual chats

Each chat on ClankWorld can use a different proxy. This lets you try different models with different characters, or keep one chat on the platform default while another uses your own API key.

## Selecting a Proxy for a Chat

<Steps>
  ### Open the Proxy modal

  In the chat you want to configure, open the **Proxy** settings.

  </Frame>

  ### Choose a proxy

  You'll see a list of your saved proxies plus the **ClankWorld Default** option. Select the one you want for this chat.

  ### Pick a model (if applicable)

  For proxies with multiple models (DeepSeek, Claude, Gemini), a **Model** dropdown appears after selecting the proxy. Choose the specific model you want.

  For **Custom** and **OpenRouter** proxies, the model is set during proxy configuration.

  </Frame>

  ### Save

  Click **Save** to apply. The chat will now use the selected proxy and model for all future messages.
</Steps>

## Switching Back to Default

Open the Proxy modal, select **ClankWorld Default**, and click **Save**. If you've already been using a custom proxy, you can also click **Reset to Default** at the bottom of the modal.

## How It Works

* Proxy selections are **per-chat** — changing one chat doesn't affect others
* Your saved proxies are **global** — configured once, available in any chat
* API keys are **encrypted at rest** and never exposed in the UI after saving
* The proxy modal shows the currently active proxy with a checkmark
