Compare available video generation models by capability, speed, and DA cost to pick the right one for your use case.
OpenDunes serves video generation through the same base URL and authentication you already use for text, via POST /v1/videos. The model catalog lists 16 live video models; this guide explains how to choose between them.
Different video models optimize for different trade-offs. Before picking one, answer these questions:
Video models take a text prompt (text-to-video). Those whose input_modalities include image also take pictures: a first or last frame — see Turn an Image into a Video — or reference pictures that guide the subject and style — see Guide a Video with Reference Images.

Social media content — prioritize speed and low cost. google/veo-3.1-fast and minimax/hailuo-2.3 sit at the low end of the price range with quick turnaround.
Product demos and presentations — prioritize visual fidelity. google/veo-3.1 and openai/sora-2-pro deliver higher-end output at a higher per-second rate.
Creative / artistic — prioritize prompt expressiveness. Models like x-ai/grok-imagine-video handle stylized prompts differently; check each model's detail page and compare outputs on your own prompts.
Each model's price is written as its DA per second of video:
