| # WeDetect-tiny — browser ONNX (int8) |
|
|
| Browser-ready **int8 ONNX** export of **WeDetect-tiny**, an open-vocabulary object detector |
| (text-prompted boxes). Two towers run client-side via `onnxruntime-web` (WebGPU, WASM fallback): |
|
|
| | file | size | role | |
| |---|---|---| |
| | `wedetect_tiny_language_int8.onnx` | ~279 MB | XLM-R text encoder → prompt features (once per prompt set) | |
| | `wedetect_tiny_vision_int8.onnx` | ~38 MB | image encoder + detection head (per image) | |
|
|
| Pipeline: prompts → XLM-R tokenizer (`Xenova/xlm-roberta-base`) → `language.onnx` → text features; |
| image → letterbox 640 → `vision.onnx` → decoded xyxy + sigmoid scores → score filter + class-agnostic |
| NMS + rescale. |

| ## License — GPL-3.0 |
|
|
| WeDetect is **GPL-3.0**. These ONNX weights are a derived export of the upstream GPL model and are |
| therefore distributed under **GPL-3.0-only**. Using them keeps you within GPL terms. |
|
|
| **Upstream / attribution:** WeDetect by **WeChatCV** — https://github.com/WeChatCV/WeDetect |
| (GPL-3.0). This repository redistributes an ONNX/int8 export of that model with no change to its |
| license. Corresponding source (model definition + training/export pipeline) lives in the upstream |
| project; the browser export/decoder is in the momoto-plugins repo (also GPL-3.0): |
| https://github.com/sweetlhare/momoto-plugins (`src/copyleft/wedetect.js`). |
|
|
| ## How it's used |
|
|
| Loaded at runtime by the **momoto** WeDetect plugin (`momoto-plugins/src/copyleft/wedetect.js`), |
| which points `meta.assets` at the two ONNX URLs here. The plugin is opt-in and never bundled into a |
| closed build — GPL bytes are fetched from this public GPL host at the user's choice, keeping the |
| closed core clear of copyleft. Self-hosters can override the asset URLs. |
