In our live test, it upscaled a 1024px input to a full 2048x2048 watermark-free native PNG in 60.3s, achieving an edge correlation of 0.6668 that significantly outperforms traditional bicubic interpolation while providing uncompromising zero-upload privacy.

| Fixture findings | Under the 2048px standard anchor, BIRME's local WebGPU super-resolution outputs a 2048x2048 native PNG with 26.97 dB PSNR, 0.8897 SSIM, 0.6668 edge correlation (+17.9% over bicubic baseline), and 16.08 dB plate PSNR, completing in 60.3s purely offline on the client. | Upscaled 4X from 512px to 2048×2048 with 28.05 dB PSNR and 0.8979 SSIM, preserving sharp brass robot edges, wooden sign lettering, and micro calibration plate lines. |
| Original historical observation | BIRME AI Enhance runs purely offline via browser WebGPU/WASM, upscaling 1024x1024 to 2048x2048 with an edge correlation of 0.6668, delivering significantly better detail than bicubic interpolation. | Upscaling the 512×512 canonical anchor at 4X (consuming 2 free credits) produces a native 2048×2048 JPEG (PSNR = 28.05 dB, SSIM = 0.8979, edge_corr = 0.7118, plate_psnr_db = 16.85 dB, server wait 6.42s) with sharp brass robot details, wooden sign lettering, and calibration plate lines. |
