8## Tools
9 
10- `list_image_models`: call first. Use only returned `name`, `sizes`, `qualities`, `styles`, `maxInputImages`, and pricing. Do not invent model ids or sizes.
11- `generate_image`: `prompt` required; `model` optional (omit to use the default `gpt-image-2.5-sunburst`); optional `images`, `size`, `quality`, `style`.
12  - Default model: `gpt-image-2.5-sunburst` when the catalog lists it; otherwise use another GPT Image 2.5 model or the closest available model.
13  - Default size when the user has no size preference (1080p class): 16:9 -> `1536x864`, 9:16 -> `864x1536`, 1:1 -> `1024x1024`; otherwise pick the catalog size matching the requested aspect.
14  - No `images` → new generation.
15  - One or more `images` (URLs) → reference/edit generation. Do not exceed `maxInputImages`.
16- Credit (积分) estimate runs automatically. If the user must confirm, wait. Do not retry a rejected cost.
17 
18Do not call other image APIs, CLIs, or local scripts.
