  • total: $0.02

Available Parameters

  • aspect_ratio: Output aspect ratio. All 9 canonical ratios are accepted; if the upstream provider does not natively support a given ratio, the system maps to the closest one. (Options: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9, 9:21)
  • num_inference_steps: Number of inference steps. (Options: 4, 6, 8, 10)
  • guidance_scale: How closely to follow the prompt. (Options: 1.5, 2.0, 2.5, 3.0, 3.5)
  • output_format: Output image format. (Options: jpeg, png)
  • strength: Image transformation strength for img2img (0.0-1.0). Lower keeps more of the original.
