Runware added Seedance 2.5 Flash, the lower-cost tier of ByteDance's Seedance 2.5 video model. Runware says it generates at nearly twice the speed of the full model.

Clips run 4 to 30 seconds with synchronized audio, at 480p or 720p. You can start from text, from first and last frames, or from up to 10 reference images, 5 reference videos and 5 audio clips. To edit or extend an existing clip, pass it in inputs.video. Set settings.operation to edit or extend to pick the mode, or leave it out and the prompt decides.

Runware's docs list text and image to video at $0.0678 per second for 480p and $0.152 for 720p. Video-to-video is $0.0833 and $0.187. If you already call Seedance 2.5 on Runware, switch the model ID to bytedance:seedance@2.5-flash.
