ByteDance Seedance 2.5
ByteDance's flagship multimodal video model — native synchronized audio, clips up to 30 seconds, and large reference sets for character and scene consistency.
Seedance 2.5 is a cloud video-generation model from ByteDance. It produces short video clips from a text prompt, a starting image, or by interpolating between a first and last frame. It can also take reference video and audio to guide the result. Clips run up to 30s at 1080p with a synchronized audio track. It also supports seed control and reference images. It runs through ByteDance, OpenRouter, Runware, and Replicate using your own API key, from about $0.2311 per second of output.

Samples
Generated with Seedance 2.5 via Runware. The same two prompts run against every video model in the catalog (one landscape, one portrait), so the only thing that changes between two models’ clips is the model.

Three Seedance drafts and one 1080p finish cost us $4.62. Rendering all three tries at 1080p would have cost $9.21.
One 30-second unbroken AI take cost us $7.43. The old model got the same script and 15 seconds. Watch both decide the upgrade.
