-Everything runs in your browser. The model (~2 GB) is downloaded once, cached, and executed via ONNX Runtime Web. No server, no uploads.

-Model artifacts: [shreyask/falcon-perception-onnx-webgpu](https://huggingface.co/shreyask/falcon-perception-onnx-webgpu).

-The critical file is `unified_v2.onnx`, which adds 2D golden RoPE on image tokens. The original `unified.onnx` dropped it, flipping presence→absence and producing zero detections.

-## Requirements
-Chrome / Edge 113+ with WebGPU.
+ONNX weights: [shreyask/falcon-perception-onnx-webgpu](https://huggingface.co/shreyask/falcon-perception-onnx-webgpu). The key file is `unified_v2.onnx`, which restores 2D golden RoPE on image tokens (missing in v1).
