Stable Diffusion 3

POST
/sd/v2beta/stable-image/generate/sd3
Generate an image using a Stable Diffusion 3 model:
SD3 Medium - the 2 billion parameter model
SD3 Large - the 8 billion parameter model
SD3 Large Turbo - the 8 billion parameter model with a faster inference time
This API is powered by Fireworks AI.
API status can be reviewed here.

Try it out#

Grab your API key and head over to one of the following sites:
Open Fireworks Playground
Open Google Colab

How to use#

Please invoke this endpoint with a POST request.
The headers of the request must include an API key in the authorization field. The body of the request must be
multipart/form-data. The accept header should be set to one of the following:
image/* to receive the image in the format specified by the output_format parameter.
application/json to receive the image encoded as base64 in a JSON response.

Generating with a prompt#

Commonly referred to as text-to-image, this mode generates an image from text alone. While the only required
parameter is the prompt, it also supports an aspect_ratio parameter which can be used to control the
aspect ratio of the generated image.

Generating with a prompt and an image#

Commonly referred to as image-to-image, this mode also generates an image from text but uses an existing image as the
starting point. The required parameters are:
prompt - text to generate the image from
image - the image to use as the starting point for the generation
strength - controls how much influence the image parameter has on the output image
mode - must be set to image-to-image
Note: maximum request size is 10MiB.

Optional Parameters:#

Both modes support the following optional parameters:
model - the model to use (SD3 Medium, SD3 Large, or SD3 Large Turbo)
output_format - the the format of the output image
seed - the randomness seed to use for the generation
negative_prompt - keywords of what you do not wish to see in the output image
Note: for more details about these parameters please see the request schema below.

Output#

The resolution of the generated image will be 1MP. The default resolution is 1024x1024.

Credits#

SD3 Medium: Flat rate of 3.5 credits per successful generation.
SD3 Large: Flat rate of 6.5 credits per successful generation.
SD3 Large Turbo: Flat rate of 4 credits per successful generation.
As always, you will not be charged for failed generations.
