Runware added [Seedance 2.5 Flash](<https://x.com/runware/status/2121845683732774962>), 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](<https://runware.ai/docs/models/bytedance-seedance-2-5-flash>) 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`.
