Flux Redux Dev

FLUX Redux Dev is a versatile image variation model that generates new images inspired by your source image. Upload an image and the model creates variations that capture the essence of your original while exploring new creative possibilities.

Why It Stands Out

Image-driven generation: Create variations based on your source image's style, composition, and content.
Flexible resolution: Customize width and height independently for any aspect ratio.
Batch generation: Create multiple variations in a single request.
Multiple output formats: Export as JPEG or PNG based on your needs.
Fine-tuned control: Adjust guidance scale and inference steps for precise results.
Reproducibility: Use the seed parameter to recreate exact results.

Parameters

Parameter	Required	Description
image	Yes	Source image for variation (upload or public URL).
width	No	Output width in pixels (default: 1024).
height	No	Output height in pixels (default: 1024).
num_inference_steps	No	Quality/speed trade-off (default: 28).
guidance_scale	No	Variation strength (default: 3.5).
num_images	No	Number of images to generate (default: 1).
seed	No	Set for reproducibility; -1 for random.
output_format	No	Output format: jpeg or png (default: jpeg).
enable_base64_output	No	Return base64 string instead of URL (API only).
enable_sync_mode	No	Wait for result before returning response (API only).

How to Use

Upload your source image — drag and drop a file or paste a public URL.
Set dimensions — adjust width and height for your desired output size.
Adjust parameters (optional) — fine-tune guidance scale and inference steps.
Set num_images — generate multiple variations at once.
Click Run and download your image variations.

Best Use Cases

Creative Exploration — Generate multiple variations of a concept to explore possibilities.
Design Iteration — Create variations of designs for A/B testing or client options.
Art Direction — Explore different interpretations of a visual concept.
Content Diversification — Generate multiple unique images from a single source.
Style Exploration — Discover new visual directions based on existing images.

Per image	$0.025

Pro Tips for Best Quality

The model generates variations based purely on the source image's visual content.
Use lower guidance scale (2–3) for subtle variations closer to the original.
Use higher guidance scale (4–5) for more dramatic departures from the source.
Generate multiple images (num_images > 1) to explore the variation space.
Fix the seed when adjusting other parameters to isolate their effect.
Use PNG format when you need higher quality or transparency support.

Notes

Ensure uploaded image URLs are publicly accessible.
Processing time varies based on resolution and current queue load.
Please ensure your content complies with usage guidelines.

Flux Redux Dev API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/wavespeed-ai/flux-redux-dev with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Flux Redux Dev below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/wavespeed-ai/flux-redux-dev" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "image": "https://example.com/your-input.jpg",
    "size": "1024*1024",
    "num_inference_steps": 28,
    "guidance_scale": 3.5,
    "num_images": 1,
    "seed": -1,
    "output_format": "jpeg",
    "enable_base64_output": false,
    "enable_sync_mode": false
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].

Node.js example

// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("wavespeed-ai/flux-redux-dev", {
        "image": "https://example.com/your-input.jpg",
        "size": "1024*1024",
        "num_inference_steps": 28,
        "guidance_scale": 3.5,
        "num_images": 1,
        "seed": -1,
        "output_format": "jpeg",
        "enable_base64_output": false,
        "enable_sync_mode": false
});

console.log(result.outputs[0]); // → URL of the generated output

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "wavespeed-ai/flux-redux-dev",
    {
    "image": "https://example.com/your-input.jpg",
    "size": "1024*1024",
    "num_inference_steps": 28,
    "guidance_scale": 3.5,
    "num_images": 1,
    "seed": -1,
    "output_format": "jpeg",
    "enable_base64_output": false,
    "enable_sync_mode": false
}
)

print(output["outputs"][0])  # → URL of the generated output

Flux Redux Dev API — Frequently asked questions

What is the Flux Redux Dev API?

Flux Redux Dev is a WaveSpeedAI model for image editing, exposed as a REST API on WaveSpeedAI. FLUX.1 Redux [dev] adapts FLUX.1 base models to generate subtle image variations and easy image-to-image restyling for refinement. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Flux Redux Dev API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/wavespeed-ai/flux-redux-dev.

How much does Flux Redux Dev cost per run?

Flux Redux Dev starts at $0.025 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Flux Redux Dev accept?

Key inputs: `image`, `size`, `seed`, `guidance_scale`, `num_inference_steps`, `enable_base64_output`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/wavespeed-ai/flux-redux-dev.

How long does Flux Redux Dev take to generate?

Average end-to-end generation time on WaveSpeedAI is around 16 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Flux Redux Dev outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (WaveSpeedAI). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
