Description: Grok Imagine Video 1.5 is xAI’s current video model for text-to-video and image-to-video with native audio, up to 1080p and 15s.

## Modes and inputs

  - Prompt only, no input images
- Image → Video (`img->vid`)
  - `as: "first_frame"`: exactly 1 (required)
  - At most 1 inputs in total

Input roles, set in `inputs[].as` (omit it, or send `auto`, to let Mynth assign one):
- `first_frame`: The frame the video opens on

## Output
- Resolutions: 480p, 720p, 1080p (default 480p)
- Duration: 1 to 15 seconds (default 8)
- Audio: yes, on by default
- Negative prompt: not supported (dropped, no error)

## Pricing (USD)
- Per second (480p): $0.080
- Per second (720p): $0.14
- Per second (1080p): $0.25
- Only successful results are charged.
