# Nano Banana API

**Model Page:** [Nano Banana API](https://apiframe.ai/models/nano-banana)

Community model card for calling Nano Banana through a REST API.

This repo documents the `nano-banana` model as exposed by Apiframe: Google's Gemini 2.5 Flash Image, text-to-image and image-to-image, up to 14 reference images, mask-free edits from a text prompt. Related ids on the same endpoint: `nano-banana-pro`, `nano-banana-2`, `nano-banana-2-lite`.

This repository does not host weights. Nano Banana is a closed model. Inference runs remotely.

## Model description

| | |
|---|---|
| Architecture | Gemini 2.5 Flash Image (Nano Banana) |
| Task | text-to-image; image-to-image (up to 14 references) |
| Output | 1 image |
| Aspect ratios | `1:1`, `3:4`, `4:3`, `9:16`, `16:9` |
| Typical latency | ~9s |

## How to use

```bash
pip install requests
```

```python
import os
import time
import requests

API = "https://api.apiframe.ai/v2"
headers = {
    "X-API-Key": os.environ["APIFRAME_API_KEY"],
    "Content-Type": "application/json",
}

job = requests.post(
    f"{API}/images/generate",
    headers=headers,
    json={
        "model": "nano-banana",
        "prompt": "a serene mountain lake at dawn",
        "nanoBananaParams": {
            "aspect_ratio": "16:9",
            "output_format": "png",
        },
    },
).json()

while True:
    result = requests.get(f"{API}/jobs/{job['jobId']}", headers=headers).json()
    if result["status"] in ("COMPLETED", "FAILED"):
        break
    time.sleep(2)

print(result.get("result"))
```

`result["images"]` is a list with one CDN URL. Pass `webhookUrl` on the generate call if you do not want to poll.

### Image-to-image

```python
import os
import requests

headers = {
    "X-API-Key": os.environ["APIFRAME_API_KEY"],
    "Content-Type": "application/json",
}

requests.post(
    "https://api.apiframe.ai/v2/images/generate",
    headers=headers,
    json={
        "model": "nano-banana",
        "prompt": "change the wall color to sage green, keep everything else the same",
        "nanoBananaParams": {
            "image_input": ["https://example.com/photo.jpg"],
            "output_format": "png",
        },
    },
)
```

Swap `model` for `nano-banana-2` or `nano-banana-pro` to use a later variant. Those ids also accept `resolution` (`1K`, `2K`, `4K`).

## Limitations

- Closed model. No weights, fine-tuning, or local inference.
- Requires an Apiframe API key (`X-API-Key`).
- Outputs carry Google's SynthID watermark.
- Commercial use follows Google's terms.
- Generated media is retained on the CDN for 90 days.
