# cf-solver-models

ONNX models used by [VeyraAgent/cf-solver](https://github.com/VeyraAgent/cf-solver).
Kept out of the GitHub repo to keep it light — download them here instead.

## Files

| model | size | used by |
|---|---|---|
| `models/siamese.onnx` | 56 MB | image recognition |
| `models/yolov11n_captcha.onnx` | 10 MB | object detection |
| `solvers/aliyun/best.onnx` | 10 MB | Aliyun slide |
| `solvers/geetest/models/geetest_v4_icon.onnx` | 2.3 MB | GeeTest v4 icons |
| `solvers/recaptcha/models/recaptcha_cls_s.onnx` | 20 MB | reCAPTCHA tile classifier |
| `solvers/rotate/rotate_model.onnx` | 1.1 MB | rotation |
| `solvers/vk/captcha_model.onnx` | 1.1 MB | VK CTC OCR |
| `solvers/vk/ctc_model.onnx` | 1.5 KB | VK CTC decode |

## Download all

```bash
./scripts/fetch_models.sh          # into the repo layout
HF_TOKEN=hf_xxx ./scripts/fetch_models.sh   # optional, only if the repo is private
```

Direct:

```bash
curl -fLO https://huggingface.co/VeyraAgent/cf-solver-models/resolve/main/solvers/recaptcha/models/recaptcha_cls_s.onnx
```

Each file keeps its repo-relative path, so dropping the tree back into a
`cf-solver` clone restores every solver.
