Nano Banana 2 Edit | Fast Image Editing API

Google Nano Banana 2 Edit

Nano Banana 2 Edit (Gemini 3.1 Flash Image) is Google’s advanced AI-powered image editing and generation model, designed to make visual transformation as intuitive as describing it in words. Built on Google’s cutting-edge computer vision and generative research, it combines precision, flexibility, and semantic awareness for professional-grade editing.

Why Choose This?

Multi-image reference Upload up to 14 reference images for complex edits and compositions.
Multi-resolution support Output in 1K, 2K, or 4K resolution based on your needs.
Flexible aspect ratios Multiple options including 1:1, 3:2, 2:3, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9, 1:4, 4:1, 1:8, and 8:1.
Prompt Enhancer Built-in tool to automatically improve your edit descriptions.
Format choice Export in PNG or JPEG format.

Parameters

Parameter	Required	Description

How to Use

Upload reference images — add the images you want to edit (up to 14 images).
Write your prompt — describe the edit clearly (e.g., "Change the man to a woman").
Choose aspect ratio (optional) — select a preset or leave empty for default.
Select resolution — choose 1K, 2K, or 4K based on your needs.
Choose output format — PNG for transparency support, JPEG for smaller file size.
Use Prompt Enhancer (optional) — click to automatically refine your description.
Run — submit and download your edited image.

Pricing

Resolution	Cost
0.5k	$0.045
1k	$0.07
2k	$0.105
4k	$0.14
Web search	+$0.014
Image search	+$0.014

Best Use Cases

Character Modification — Change attributes like gender, age, clothing, or appearance.
Object Replacement — Swap elements within images while preserving context.
Style Transfer — Apply different visual styles to existing images.
Text Editing — Modify on-image text while maintaining design consistency.
Scene Adjustment — Change backgrounds, lighting, or environmental elements.

Pro Tips

Use clear, specific edit instructions for best results (e.g., "Change the man to a woman" rather than "modify the person").
Start with fewer reference images (1–3) for simpler edits.
More reference images can help with complex compositions but may affect stability.
2K outputs are charged at 1.5× the standard rate; 4K at 2× the standard rate.
Try the Prompt Enhancer to automatically improve your descriptions.

Notes

Both images and prompt are required fields.
Maximum reference images: 14 (recommended: fewer images for better stability).
If aspect_ratio is not selected, the model uses a default ratio.
2K resolution costs 1.5× and 4K resolution costs 2× the standard rate.
Ensure your prompts comply with Google's Safety Guidelines.

Nano Banana 2 Edit API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/google/nano-banana-2/edit 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 Nano Banana 2 Edit below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/google/nano-banana-2/edit" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "aspect_ratio": "1:1",
    "resolution": "1k",
    "enable_web_search": false,
    "enable_image_search": false,
    "output_format": "png",
    "enable_sync_mode": false,
    "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("google/nano-banana-2/edit", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "aspect_ratio": "1:1",
        "resolution": "1k",
        "enable_web_search": false,
        "enable_image_search": false,
        "output_format": "png",
        "enable_sync_mode": false,
        "enable_base64_output": false
});

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

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "google/nano-banana-2/edit",
    {
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "aspect_ratio": "1:1",
    "resolution": "1k",
    "enable_web_search": false,
    "enable_image_search": false,
    "output_format": "png",
    "enable_sync_mode": false,
    "enable_base64_output": false
}
)

Nano Banana 2 Edit API — Frequently asked questions

What is the Nano Banana 2 Edit API?

Nano Banana 2 Edit is a Google model for image editing, exposed as a REST API on WaveSpeedAI. Google Nano Banana 2 Edit (Gemini 3.1 Flash Image) enables advanced image editing with 4K-capable output, fast iteration, and precise instruction following. Supports text translation, localization within images, and maintains subject consistency during edits. 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 Nano Banana 2 Edit 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/google/google-nano-banana-2-edit.

How much does Nano Banana 2 Edit cost per run?

Nano Banana 2 Edit starts at $0.070 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 Nano Banana 2 Edit accept?

Key inputs: `prompt`, `images`, `aspect_ratio`, `resolution`, `enable_base64_output`, `enable_image_search`. 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/google/google-nano-banana-2-edit.

How do I get started with the Nano Banana 2 Edit API?

Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.

Can I use Nano Banana 2 Edit outputs commercially?

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