Pro Tips for Best Results

Flash is ideal for text corrections and simple modifications.
Be precise about what to change: specify the original and replacement text.
Use quotes around text to be replaced for clarity.
At $0.01 per image, experiment freely to find the best result.
For complex scene changes or background swaps, consider Photon Modify.
Perfect for fixing typos, updating dates, or changing labels.

Notes

If using a URL, ensure it is publicly accessible.
Flash mode prioritizes speed — ideal for quick edits and high volume.
Best for text modifications and simple element changes.
For more complex edits, use the standard Photon Modify model.

Photon Flash Modify API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/luma/photon-flash-modify 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 Photon Flash Modify below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/luma/photon-flash-modify" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "enable_base64_output": 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("luma/photon-flash-modify", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "image": "https://example.com/your-input.jpg",
        "enable_base64_output": false
});

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

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "luma/photon-flash-modify",
    {
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "image": "https://example.com/your-input.jpg",
    "enable_base64_output": false
}
)

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

Photon Flash Modify API — Frequently asked questions

What is the Photon Flash Modify API?

Photon Flash Modify is a Luma model for image editing, exposed as a REST API on WaveSpeedAI. Luma Photon Flash Modify is a text-to-image model optimized for creative image generation and prompt-driven modifications. 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 Photon Flash Modify 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/luma/luma-photon-flash-modify.

How much does Photon Flash Modify cost per run?

Photon Flash Modify starts at $0.010 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 Photon Flash Modify accept?

Key inputs: `prompt`, `image`, `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/luma/luma-photon-flash-modify.

How long does Photon Flash Modify take to generate?

Average end-to-end generation time on WaveSpeedAI is around 15 seconds per request — measured across recent runs. Queue time scales with global demand; live status is visible in the prediction record.

Can I use Photon Flash Modify outputs commercially?

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