Key Capabilities of Hunyuan Fast
Hunyuan Fast offers a focused set of capabilities for AI video production. Key features include text-to-video generation with configurable aspect ratios. The model accepts both text prompts and reference images as input, allowing you to animate existing stills or generate entirely new footage from descriptions.

Using Hunyuan Fast in DaVinciDreams
Using Hunyuan Fast in DaVinciDreams starts in the AI Script Generator wizard, where you select it as your video model during step one. The generator then creates text prompts optimized for Hunyuan Fast for every clip in your screenplay. Alternatively, you can select Hunyuan Fast directly in the editor workspace when adding or regenerating individual clips. Each generation request goes through the PiAPI API and returns a video clip that appears immediately in your asset panel and on the timeline. If you have your own PiAPI API key, the BYOK system uses it automatically — bypassing credit deduction and saving up to 40% compared to platform credits. The webhook system and fallback polling ensure reliable delivery even under high API load.
