Seedance 2.5 API Launched, Call Price About 50% More Expensive Than 2.0

According to Dongcha Beating monitoring, Volcano Engine has officially released the Seedance 2.5 API. The new model can generate a 30-second video in a single inference, doubling the length from Seedance 2.0's 15 seconds. It can reference up to 50 full-modal assets simultaneously, and also supports video extension and selective editing.

The key upgrade aims to enable better orchestration of long videos. Seedance 2.5 can recognize second-level timestamps in the prompt to organize shots and actions accordingly. In an official demo, it was able to dynamically schedule six to seven animal characters within 30 seconds. Despite the continuous overlap and occlusion of characters, the relationship in appearance and size remained stable.

With increased capabilities comes increased call costs. The pricing for Volcano Ark is currently set at $42 per million tokens with video input and $70 per million tokens without video input; compared to Seedance 2.0, priced at $28 and $46 respectively. The new model is approximately 50% more expensive.
