### OpenAI `gpt-image-2`
OpenAI image generation defaults to `openai/gpt-image-2`. The older
`openai/gpt-image-1` model can still be selected explicitly, but new OpenAI
image-generation and image-editing requests should use `gpt-image-2`.
`gpt-image-2` supports both text-to-image generation and reference-image
editing through the same `image_generate` tool. OpenClaw forwards `prompt`,
`count`, `size`, and reference images to OpenAI. OpenAI does not receive
`aspectRatio` or `resolution` directly; when possible OpenClaw maps those into a
supported `size`, otherwise the tool reports them as ignored overrides.
Generate one 4K landscape image:
```
/tool image_generate action=generate model=openai/gpt-image-2 prompt="A clean editorial poster for OpenClaw image generation" size=3840x2160 count=1
```
Generate two square images:
```
/tool image_generate action=generate model=openai/gpt-image-2 prompt="Two visual directions for a calm productivity app icon" size=1024x1024 count=2

Edit one local reference image:
```
/tool image_generate action=generate model=openai/gpt-image-2 prompt="Keep the subject, replace the background with a bright studio setup" image=/path/to/reference.png size=1024x1536
