Seedance 2.5 now available on Vercel AI Gateway

ByteDance's Seedance 2.5 video generation model is now available on Vercel's AI Gateway, enabling single-clip generation of up to 30 seconds with consistent camera movement and continuity, plus local editing of finished videos. The model accepts text, video, image, and audio inputs in one request, supports prompts in over ten languages, and can be accessed via the AI SDK by setting the model to 'bytedance/seedance-2.5' and calling 'generateVideo'.

Seedance 2.5 https://vercel.com/ai-gateway/models/seedance-2.5 from ByteDance is now available on AI Gateway. It generates up to 30 seconds in a single clip, holding camera movement and continuity without stitching shots together in post. Short clips can also be extended with character, scene, and camera movement carried over. Seedance 2.5 supports text, video, image, and audio as inputs in the same request, following a subject's appearance from one asset and the motion or camera work from another. On a finished video it edits locally, swapping backgrounds, products, or characters while the frame, camera, and pacing stay put, which is how one cut becomes several versions. Prompts work in more than ten languages. Set model to bytedance/seedance-2.5 and call generateVideo from the AI SDK https://ai-sdk.dev/ : Pass in image URLs under referenceImages and point at them in the prompt with Image 1 , Image 2 . referenceVideos is numbered separately from the images, so Video 1 and Image 1 can appear in the same prompt: motion from one asset, appearance from another. A reference feeds a new generation, contributing motion, camera work, or pacing to something the model builds from scratch. Editing changes a finished video in place. Mixing the two roles in one prompt gives less stable results, so be explicit about what each source asset is for.
