Vendor: BytePlus · Official API docs: OmniHuman 1.5 overview

ByteDance models on the BytePlus Vision AI platform. OmniHuman 1.5 is an audio-driven avatar model — give it a single portrait image plus an audio clip and it generates a talking/performing video (expression and motion are driven by the audio, not a text prompt). A separate ByteDance Upscaler restores and upscales an existing clip to 1080p.

Cost scales with the duration of the generated video (driven by the length of the input audio clip).
