    "width": 1024,
    "height": 1024
  }'

Python

import get3w

output = get3w.run(
    "get3w/flux-dev",
    {
        "prompt": "A serene Japanese garden with cherry blossoms, golden hour lighting",
        "width": 1024,
        "height": 1024
    }
)

print(output["outputs"][0])

JavaScript

const output = await client.run("get3w/flux-dev", {
    prompt: "A serene Japanese garden with cherry blossoms, golden hour lighting",
    width: 1024,
    height: 1024,
});

console.log(output.outputs[0]);

Choosing a Model

Model	Speed	Quality	Best For
FLUX Dev	Medium	High	General purpose
FLUX Schnell	Fast	Good	Quick iterations
Seedream V4.5	Medium	Very High	Photorealistic images
Nano Banana Pro	Fast	High	Creative styles
Stable Diffusion 3.5	Medium	High	Fine-tuned control

Common Parameters

Parameter	Type	Description	Default
prompt	string	Text description of the image	Required
width	integer	Output width in pixels	1024
height	integer	Output height in pixels	1024
seed	integer	Random seed for reproducibility	Random
steps	integer	Number of inference steps	Model default

Tips for Better Results

1. Be specific — "A golden retriever playing fetch in a park at sunset" is better than "a dog"
2. Include style keywords — Add "cinematic", "photorealistic", "watercolor", etc.
3. Specify lighting — "golden hour", "studio lighting", "dramatic shadows"
4. Set dimensions — Use the aspect ratio that matches your use case
5. Use the Prompt Enhancer — Available in the web interface
