API Schema
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.
The safety tolerance level for the generated image. 1 being the most strict and 5 being the most permissive.
2
Possible values: The format of the generated image.
jpeg
Possible values: The aspect ratio of the generated image.
16:9
Possible values: The text prompt describing the content, style, or composition of the image to be generated.
The number of images to generate.
1
The same seed and the same prompt given to the same version of the model will output the same image every time.

Quick Example
Let's generate an image of the specified size using a simple prompt.
import requests
def main():
response = requests.post(
"https://api.aimlapi.com/v1/images/generations",
headers={
# Insert your AIML API Key instead of <YOUR_AIMLAPI_KEY>:
"Authorization": "Bearer <YOUR_AIMLAPI_KEY>",
"Content-Type": "application/json",
},
json={
"prompt": "A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.",
"model": "flux/kontext-max/text-to-image",
"aspect_ratio": "21:9"
}
)
# response.raise_for_status()
data = response.json()
print("Generation:", data)
if __name__ == "__main__":
main()
We obtained the following 1568x672 image by running this code example:

'A T-Rex relaxing on a beach, lying on a sun lounger and wearing sunglasses.'
