This model has other modes with their own ids: fast-lcm-diffusion, fast-lcm-diffusion/inpainting.

Run it

Quote the input, start the generation with the quote, then poll the job. Set RAYWAKE_API_KEY first; see Authentication.

# 1. Price the exact input (quotes are valid for up to 10 minutes)
curl -s https://api.raywake.com/v1/quotes \
  -H "Authorization: Bearer $RAYWAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "fast-lcm-diffusion/image-to-image",
  "input": {
    "image_url": "https://example.com/input.png",
    "prompt": "A red ceramic cup on a wooden table, soft morning light"
  }
}'

# 2. Start the generation with the quote_id from step 1
curl -s https://api.raywake.com/v1/generate \
  -H "Authorization: Bearer $RAYWAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"model": "fast-lcm-diffusion/image-to-image", "quote_id": "QUOTE_ID", "input": {"image_url":"https://example.com/input.png","prompt":"A red ceramic cup on a wooden table, soft morning light"}}'

# 3. Poll until the status is terminal
curl -s https://api.raywake.com/v1/jobs/JOB_ID \

Input

Input fields for fast-lcm-diffusion/image-to-image
NameTypeDescription
image_urlrequiredstring (image URL)
The URL of the image to use as a starting point for the generation.
promptrequiredstring
The prompt to use for generating the image. Be as descriptive as possible for best results.
negative_promptstring
The negative prompt to use.Use it to address details that you don't want in the image. This could be colors, objects, scenery and even the small details (e.g. moustache, blurry, low resolution).
image_sizestring (enum)
The size of the generated image.

Default: square_hd

One of: square_hd, square, portrait_4_3, portrait_16_9, landscape_4_3, landscape_16_9

num_inference_stepsinteger
The number of inference steps to perform.

Default: 6

guidance_scalenumber
The CFG (Classifier Free Guidance) scale is a measure of how close you want the model to stick to your prompt when looking for a related image to show you.

Default: 1.5

strengthnumber
determines how much the generated image resembles the initial image

Default: 0.95

seedinteger
The same seed and the same prompt given to the same version of Stable Diffusion will output the same image every time.
sync_modeboolean
If `True`, the media will be returned as a data URI and the output data won't be available in the request history.

Default: false

num_imagesinteger
The number of images to generate.

Default: 1

enable_prompt_expansionboolean
If set to true, the prompt will be expanded with additional prompts.

Default: false

formatstring (enum)
The format of the generated image.

Default: jpeg

One of: jpeg, png

preserve_aspect_ratioboolean
If set to true, the aspect ratio of the generated image will be preserved even if the image size is too large. However, if the image is not a multiple of 32 in width or height, it will be resized to the nearest multiple of 32. By default, this snapping to the nearest multiple of 32 will not preserve the aspect ratio. Set crop_output to True, to crop the output to the proper aspect ratio after generating.

Default: false

crop_outputboolean
If set to true, the output cropped to the proper aspect ratio after generating.

Default: false
