IP-Adapter: transfer style and subject from a reference image

Generating an image "in the style of this photo" or "with this character" used to be complicated: it required DreamBooth, LoRA, or other lengthy and costly fine-tuning processes. IP-Adapter changes the approach: it is a small add-on module that plugs into the existing model without modifying it.

It works as a "translator": it takes the reference image, extracts visual features with CLIP, and injects them into the generation process through a separate cross-attention layer. Text and image guide generation independently.

The practical result is immediate: you can use a photo of a product, a person, or a painting as a visual guide, and the model respects both the text content and the visual characteristics of the reference.
