# GPT Image

> GPT Image 2, 2.5 Flare and 2.5 Sunburst on zurelay: sizes, quality, editing with up to 16 images.

Source: https://zurelay.com/docs/gpt-image

OpenAI’s GPT Image models: sharp detail, strong text rendering, and editing with up to 16 images, at one price for every size.

## The models

| Model | ID | Price per image | Reference images |
| --- | --- | --- | --- |
| GPT Image 2.5 Flare | `gpt-image-2.5-flare` | $0.02 | up to 16 |
| GPT Image 2.5 Sunburst | `gpt-image-2.5-sunburst` | $0.02 | up to 16 |
| GPT Image 2 | `gpt-image-2` | $0.02 | up to 16 |

GPT Image 2.5 Flare is the quick one; 2.5 Sunburst puts quality first; GPT Image 2 stays for workflows tuned to it.

## Make an image

**Python** (`main.py`):

```python
import os
from openai import OpenAI

client = OpenAI(base_url="https://api.zurelay.com/v1", api_key=os.environ["ZURELAY_API_KEY"])

result = client.images.generate(
    model="gpt-image-2.5-sunburst",
    prompt="An isometric illustration of a tiny bakery at night, warm window light, a cat on the awning",
    size="1536x1024",
    extra_body={
      "quality": "high"
    },
)
print(result.data[0].url)
```

**Node.js** (`index.mjs`):

```javascript
import OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://api.zurelay.com/v1", apiKey: process.env.ZURELAY_API_KEY });

const result = await client.images.generate({
  "model": "gpt-image-2.5-sunburst",
  "prompt": "An isometric illustration of a tiny bakery at night, warm window light, a cat on the awning",
  "size": "1536x1024",
  "quality": "high"
});
console.log(result.data[0].url);
```

**cURL**:

```bash
curl https://api.zurelay.com/v1/images/generations \
  -H "Authorization: Bearer $ZURELAY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "gpt-image-2.5-sunburst",
  "prompt": "An isometric illustration of a tiny bakery at night, warm window light, a cat on the awning",
  "size": "1536x1024",
  "quality": "high"
}'
```

## Parameters

- `size` (string): `1024x1024, 1536x1024, 1024x1536, 2048x2048, 3840x2160, 2160x3840`, or `auto`. Same price at every size.
- `quality` (string): `low`, `medium`, `high` or `auto`.
- `background` (string): `transparent`, `opaque` or `auto`. Transparent needs PNG or WebP output.
- `output_format` (string): `png`, `jpeg` or `webp`.
- `n` (integer): 1 to 4 images.

## Edit with up to 16 images

Use `client.images.edit` with one or more files, or JSON with `images`. Masks aren’t supported; describe the area to change.

Python:

```python
result = client.images.edit(
    model="gpt-image-2.5-flare",
    image=[open(f"tile-{i}.png", "rb") for i in range(1, 9)],
    prompt="Arrange the eight product photos into a clean 4 x 2 catalog grid on white.",
)
```
