https://civitai.com/models/2564225/style-greater-gpt-image-2?modelVersionId=2998634 Description Steers the model towards the style of gpt image 2. It improves details, lighting and texture a lot, though the image might end up looking slightly sloppy.

This is meant as an enhancer so play with lora strength to allow more style diversity :)

Note on versions v1.1 is closer to the images in the dataset, it adds a lot more texture and details, shifts the colors less, and affects the pose / composition a bit less too compared to v1. It has the downside of sticking more closely to the body and face of gpt-image-2 (which gets boring fairly quickly), and having some of the less pleasing repeating texture pattern of gpt2 image.

You might just prefer the effect that v1 give if you want less texture or punchier colors.
