⚠️ Beta Notice: This is an experimental feature. Results are not guaranteed to be perfect. This feature is designed for fictional and original characters — using photos of real people or public figures is not supported and may produce poor or unexpected results. Output quality depends on your reference images and prompt. We recommend testing before using in production workflows.
Upload Reference Images: Provide 1–3 reference images of your fictional character.
Describe the Outfit: Fill in outfit_description with a specific description (e.g., 'red leather jacket, black jeans, white sneakers').
Optionally Name Your Character: Add a character_name for your own reference.
Submit and Poll: Submit to /sd-2-character. Poll /predictions/{request_id}/result until status is completed.
Use the Character ID: Pass the request_id as character_id in /sd-2.0-omni-reference along with your scene prompt to generate a video featuring your character.
Frequently asked
This feature is currently in beta. Output quality can vary depending on the reference images and prompt. We recommend testing before using it in critical workflows. Credits are charged per generation regardless of output quality, as the generation process itself runs to completion.
No. This feature is designed for fictional, original, and illustrated characters only. Using photos of real people, public figures, or celebrities is not supported and may produce poor results. Such use may also raise legal and ethical concerns.
Clear, well-lit images of your original or illustrated character with a simple background. The character should be fully visible with no heavy obstructions. Illustrated or stylized art often works well.
Character accuracy depends on the quality of your reference images and how specifically you describe the outfit. This is an experimental feature and exact likeness is not guaranteed. Try using a clearer reference image or a more detailed outfit description.
Pass the `request_id` returned from a completed `sd-2-character` job as the `character_id` field in `/sd-2.0-omni-reference`. Your character will be used in the video generation.
1 clear image is enough for most cases. You can upload up to 3 images for more detail. Quality and clarity matter more than quantity.
Yes. Once created, a character_id can be used in as many video generations as you like at no additional charge.
Credits are charged when the generation completes, regardless of output quality. This is consistent with how all AI generation models work — the compute cost is incurred whether or not the result matches your expectations. We recommend testing with a low-stakes prompt first.
