About AuraFlow

Generates images from a `prompt`. `num_images` is 1 or 2, `num_inference_steps` ranges from 20 to 50, and `guidance_scale` from 0 to 20. `expand_prompt` is on by default and the expanded prompt is returned. A `seed` can be set for reproducibility.

Parameters

Send either the canonical name or the native name, not both. Canonical names
