Seedance 2.0 API Tutorial: From Zero to Your First AI Video (Python)

Seedance 2.0 is ByteDance's most advanced AI video model — multimodal references, native audio, cinematic camera control, and 4–15 second generation at up to 1080p. This tutorial walks you through the entire API workflow in Python: from getting your API key to downloading your first generated video. By the end, you'll have working code for text-to-video, image-to-video, async polling, webhook handling, and error recovery. Every code example here was tested against a live API. Note — Seedance 2.0 vs 1.5: Seedance 2.0 is rolling out progressively. You can test the complete workflow right now using seedance-1.5-pro — when 2.0 is fully available, just change the model name. All endpoints, parameters, and response formats are identical. The key differences in 2.0: multimodal references (mix images, videos, and audio as inputs), native audio generation, improved physics simulation, and video editing capabilities. Everything in this tutorial works with both versions. Get your free API key to
