# Grok

*Configuring Grok in Source*

**Pro** (you pay xAI for usage). Grok Imagine generates photorealistic images from your post keywords using your **xAI API key**. You do not need Replicate. It *generates* an image — it does not search a photo library.

## Where to enable it

Open **Source**, add **Grok** (badge **AI**, locked as **Pro** on the free plugin) to the **Automatic generation chain**, then click **Configure**. Style presets on **Automatic → Image Placement** apply when this bank generates. The Gutenberg block cannot search Grok (photo tabs only).

## Get an API key

Create a key in the [xAI console](https://console.x.ai/). Paste it in the Grok panel and click **API testing**. This dedicated bank uses your xAI key — not a Replicate token.

## Options

- **API Key** — Required. Your xAI console key.
- **Aspect Ratio** — 1:1, 16:9 (default) or 9:16.

## Billing

The xAI API is **prepaid credits**, not the free Grok app. Without credits (or a payment method), xAI rejects every request — including **API testing** in the plugin. Add credits on the [xAI billing](https://console.x.ai/team/default/billing) page.

## Time and restrictions

**Caution:** generation usually takes a few seconds. Image URLs from xAI expire; Magic Post Thumbnail downloads them immediately into your Media Library.

Previewing this bank on Source consumes xAI credits — the plugin warns you and asks for confirmation before an AI preview. The plugin does not charge per image. xAI bills the prepaid credits on the key you enter.
