# SynLayers Stage 2

This repository contains the Stage 2 checkpoints and runtime assets for SynLayers, our real-world image layer decomposition system.

The main assets in this repo are:

- `SynLayers_checkpoints/FLUX.1-dev`
- `SynLayers_checkpoints/FLUX.1-dev-Controlnet-Inpainting-Alpha`
- `SynLayers_ckpt/step_120000`
- `ckpt/trans_vae/0008000.pt`
- `ckpt/pre_trained_LoRA`
- `ckpt/prism_ft_LoRA`

These assets are used by the public SynLayers demo:
[SynLayers/synlayers](https://huggingface.co/spaces/SynLayers/synlayers)

The full pipeline uses:

1. Stage 1 bbox + whole-caption prediction from [`SynLayers/Bbox-caption-8b`](https://huggingface.co/SynLayers/Bbox-caption-8b)
2. Stage 2 layer decomposition from this repository

This repo is intended for the SynLayers decomposition pipeline rather than a single generic `DiffusionPipeline(prompt)` model.
