# Grok Imagine Refs

> Grok Imagine with **multiple reference images** (1-7). Use this endpoint when you have more than one reference image; for text-to-video or a single image use `grok_imagine`, which additionally supports 1080p.

**`image_urls` is required** — this endpoint does not support text-to-video.

**Pricing** — per second of generated video, in tokens (USD at $0.02/token). Same rates as `grok_imagine`; the number of reference images does not affect the price:

| resolution | tokens/s | USD/s |
|---|---|---|
| 480p | 2.5 | $0.05 |
| 720p | 4.7 | $0.094 |

Example: a 6s 480p video costs 15 tokens (= $0.30).
A 10s 720p video costs 47 tokens (= $0.94).

Returns an `img_uuid`; poll GET /api/v1/jobs/detail (or use `custom_callback_url`) to get the generated video.
