/v1beta/models/{model-name}:generateContent

Use Google's image model: nano-banana
If you need to support different official image generation parameters (such as aspect ratio), please use the google group for tokens.
The parameter passing for reference images is somewhat special and requires the use of temporary files. Please refer to the "Python Reference Image Generation" section in the sample code.
