image-to-image photorealistic text-to-image

About

An opinionated text-to-image model from Black Forest Labs in collaboration with Krea that excels in photorealism. Creates images that avoid the oversaturated "AI look".

Example Output

Prompt:

"a double exposure photo of a dimly lit close up emotional portrait and a dramatic and epic stormy seascape, the two images seamlessly merge into one"

All Input Parameters

{
  "prompt": "a double exposure photo of a dimly lit close up emotional portrait and a dramatic and epic stormy seascape, the two images seamlessly merge into one",
  "go_fast": true,
  "guidance": 3,
  "megapixels": "1",
  "num_outputs": 1,
  "aspect_ratio": "1:1",
  "output_format": "webp",
  "output_quality": 95,
  "prompt_strength": 0.8,
  "num_inference_steps": 28
}

Input Parameters

seed Type: integer: Random seed. Set for reproducible generation
image Type: string: Input image for image to image mode. The aspect ratio of your output will match this image
prompt (required) Type: string: Prompt for generated image
go_fast Type: booleanDefault: true: Run faster predictions with model optimized for speed (currently fp8 quantized); disable to run in original bf16. Note that outputs will not be deterministic when this is enabled, even if you set a seed.
guidance Type: numberDefault: 3Range: 0 - 10: Guidance for generated image
megapixels Default: 1: Approximate number of megapixels for generated image
num_outputs Type: integerDefault: 1Range: 1 - 4: Number of outputs to generate
aspect_ratio Default: 1:1: Aspect ratio for the generated image
output_format Default: webp: Format of the output images
output_quality Type: integerDefault: 80Range: 0 - 100: Quality when saving the output images, from 0 to 100. 100 is best quality, 0 is lowest quality. Not relevant for .png outputs
prompt_strength Type: numberDefault: 0.8Range: 0 - 1: Prompt strength when using img2img. 1.0 corresponds to full destruction of information in image
num_inference_steps Type: integerDefault: 28Range: 1 - 50: Number of denoising steps. Recommended range is 28-50, and lower number of steps produce lower quality outputs, faster.
disable_safety_checker Type: booleanDefault: false: Disable safety checker for generated images.
