Quality setting for the resulting video.

default 93

Frame count for generation, ranging from 9 to 93.

default 35

Denoising step count, trading longer processing for better quality as the count increases.

default 7

Scale for classifier-free guidance; increasing it makes generation follow the prompt more closely.

Random seed that makes generation reproducible.

About Cosmos Predict 2.5 2B · Text to Video

Generates video from a text `prompt` only. Set `num_frames` between 9 and 93, `num_inference_steps` up to 50 (default 35) and `guidance_scale` 1 to 20. A `negative_prompt` is available, and output can be mp4, webm, mov or GIF at low to maximum quality.
