Infinitalk
Infinitalk uses 1 image, 1 audio file no longer than 15 seconds, and a required prompt to generate a speaking-portrait video on Kyeo. It offers 480p or 720p plus optional `seed`; cost depends on audio duration and resolution rather than a fixed request price.

Selection guide
Use these decision points when choosing a model.
Infinitalk exposes 480p/720p and `seed`, and its total changes with audio duration. It is the workflow to test when each segment needs a calculated budget before submission.
The charge uses the signed audio duration at 8 credits per second and rounds up. A missing, invalid, or over-5-minute duration cannot be submitted. The charge uses the signed audio duration at 16 credits per second and rounds up. A missing, invalid, or over-5-minute duration cannot be submitted.
Prepare 1 supported portrait image, 1 supported audio file no longer than 15 seconds, and a non-empty prompt. Check the combination at 480p before deciding whether to rerun it at 720p.

Credit usage
Kyeo multiplies verified audio duration by 3 credits per second at 480p or 12 at 720p, then rounds up; a 15-second request costs at most 45 or 180 credits.
Before batch generation, run an A/B test with the same assets across the current model and alternatives to validate quality and avoid wasting credits.

Seedance 2.0
Seedance 2.0 / Capabilities — Text accepts no media; frames requires a first frame and allows a last frame; reference requires a prompt and at least one image, video, or audio reference. Reference media cannot be sent with endpoint-frame fields. Seedance 2.0 supports three mutually exclusive text, frame, and multimodal-reference scenes. The current callable output set is 720p, 1080p, and 4K for 4–15 seconds; video-reference requests are available only at 1080p or 4K because those are the current priced combinations. 164–3,840 credits per request
