# SynLayers Stage 2 Checkpoints

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

The main assets in this repo include:

- `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 our public Space:
[SynLayers/synlayers](https://huggingface.co/spaces/SynLayers/synlayers)

The full SynLayers system has two stages:

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

This repository is intended for the SynLayers decomposition pipeline. It is not meant to be loaded as a single generic `DiffusionPipeline(prompt)` model.
