ormbg_isnet — ExecuTorch XNNPACK

ormbg_isnet_xnnpack_fp32.pte (176.1 MB, fp32, XNNPACK-delegated)

• Source: schirrmacher/ormbg
• License: Apache-2.0
• Input: [[1, 3, 1024, 1024]] — RGB 0-1, 1024x1024
• Output: alpha mask [1,1,1024,1024] 0-1 (sigmoid)

Verification (Mac arm64, executorch 1.4.0, torch 2.13.0)

Parity vs torch fp32 eager on random input:

output	shape	max_abs_diff	corr
0	[1, 1, 1024, 1024]	2.831e-06	1.000000

Median latency over 10 runs (single Mac process, reference only — device numbers to follow): ExecuTorch 123.8 ms vs torch eager 387.3 ms.
