Quick Start

import fal_client

def on_queue_update(update):
    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "fal-ai/flux-pro/v1.1-ultra-finetuned",
    arguments={
        "prompt": "Extreme close-up of a single tiger eye, direct frontal view. Detailed iris and pupil. Sharp focus on eye texture and color. Natural lighting to capture authentic eye shine and depth. The word \"FLUX\" is painted over it in big, white brush strokes with visible texture.",
        "finetune_id": ""
    },
    with_logs=True,
    on_queue_update=on_queue_update,

OutputFormatEnum
default:"jpeg"
The format of the generated image. Default value: "jpeg"Possible values: jpeg, png
​
safety_tolerance
SafetyToleranceEnum
default:"2"
The safety tolerance level for the generated image. 1 being the most strict and 5 being the most permissive. Default value: "2"Possible values: 1, 2, 3, 4, 5, 6
​
enhance_prompt

​
finetune_id
string
required
References your specific model
​
finetune_strength
float
required
Controls finetune influence. Increase this value if your target concept isn’t showing up strongly enough. The optimal setting depends on your finetune and promptRange: 0 to 2

​
Output Schema

images
list<registry__image__fast_sdxl__models__Image>
required
The generated image files info.
​
