Biya Upscale v1.0.0 is a free, open-source portable Windows ZIP for 2 /4 AI upscaling. The first launch needs internet to download the model; inference runs locally afterward. The executable is unsigned. The only verified setup is Windows 11 + NVIDIA RTX 2050 using DirectML; other hardware is unverified. AI can alter details and distort small text.

If you can test it, please try extraction, launch, first-run model download, one upscale, and saving the result. Report your Windows version, GPU, which steps succeeded, processing time, and errors in GitHub issue #1: https://github.com/Biya-dev/Biya.... Please do not upload private images or sensitive logs.
