SD3.5-Large-IP-Adapter

This repository contains a IP-Adapter for SD3.5-Large model released by researchers from InstantX Team, where image work just like text, so it may not be responsive or interfere with other text, but we do hope you enjoy this model, have fun and share your creative works with us on Twitter.

Model Card

This is a regular IP-Adapter, where the new layers are added into all 38 blocks. We use google/siglip-so400m-patch14-384 to encode image for its superior performance, and adopt a TimeResampler to project. The image token number is set to 64.
