# wmr model hub
This repository hosts the models [wmr](https://github.com/froggeric/gemini-watermark-and-synthid-remover)
downloads for its SynthID regeneration (`--synthid-attack regen`). wmr is a command-line tool that
removes visible watermarks from Gemini / Veo / NotebookLM generated media and scrubs the invisible
**SynthID** watermark via lossy SDXL img2img regeneration (the only SynthID attack the published
literature reports as validated, confirmed here against Google's official SynthID verifier).
wmr auto-downloads the files it needs on first use and caches them under `~/.cache/wmr/`; you do
not need to download anything from here manually. Pass `--regen-no-download` to refuse the network.
The SHA256 of every file is pinned in wmr's source and verified after download.
There are two regeneration backends, each with its own model set:
## 1. CoreML SDXL (macOS Apple Silicon, fast)
Used by `--synthid-attack regen` on macOS Apple Silicon (the default there). Native CoreML
`.mlpackage` directories converted from `apple/ml-stable-diffusion` tag 1.1.1, tarred for hosting.

The UNet + VAE are converted from Stability AI's SDXL base 1.0 + `madebyollin/sdxl-vae-fp16-fix`.
The empty-prompt embeddings are pre-baked CLIP outputs (the text encoders are not shipped).
## 2. CPU sdcpp SDXL (Linux, Windows, macOS Intel)
Used by `--synthid-attack regen` on Linux, Windows, and macOS Intel, and by `--regen-backend cpu`
everywhere. Run natively via [leejet/stable-diffusion.cpp](https://github.com/leejet/stable-diffusion.cpp)
(ggml), CPU-only in the release binaries.
| File | Size | SHA256 |
|------|------|--------|
| `sd_xl_base_1.0.safetensors` | ~6.5 GB | `31e35c80fc4829d14f90153f4c74cd59c90b779f6afe05a74cd6120b893f7e5b` |

`sd_xl_base_1.0.safetensors` is the official Stability AI SDXL base 1.0 checkpoint (unchanged bytes;
its SHA is the HuggingFace LFS content oid, so it verifies identically to the upstream file).
`sdxl_vae.safetensors` is the fp16-stable VAE from `madebyollin/sdxl-vae-fp16-fix` (named
`sdxl_vae.safetensors` upstream). Both are mirrored here so the CPU path depends only on this repo.
