## Quick answer

- Only generation is billed. Uploading, moving, previewing and downloading cost no credits.
- Video is billed per second and scales with resolution; images per image, music per song, rendering per segment.
- Text and multimodal models are billed per call for Agent planning, rewriting, scripts and image understanding.
- Failed or canceled tasks return eligible credits according to the task record.
- Prices come from live backend settings; the task submission page and purchase page are authoritative.

## Capabilities

- Video models: billed per generated second; supported resolutions are shown on the page.

- Multimodal models: billed per call for image understanding, scene analysis and creative conversation.

## Billing rules

1. Check the price first: estimated credits are shown before submission.
2. Only generation is billed: uploading, moving, layout, preview and download are free.
3. Failures return automatically: failed or canceled tasks return eligible credits.
4. Do not submit twice: repeated clicks create multiple tasks and separate charges.
