A benchmark version number is specific to a test. Benchmark version numbers change rarely and only when absolutely necessary to accommodate changes in third-party applications or bug fixes.

Procyon AI Computer Vision Benchmark v2.0 v1.0.555

April 13, 2026

Fixed

  • Resolved an issue where an incorrect SNPE DLL was packaged with the WinML QNN Execution Provider runtime.
  • Model cache generated for WinML QNN Execution provider use SDK 2.39 to avoid regression in BLIP model caused by SDK 2.40 driver dependencies. 

Added

  • Model caches generated for the WinML OpenVINO Execution Provider now include the execution provider version in the cache name so that caches can be regenerated when a new OpenVINO EP is released. 
  • Improved error logging for WinML workloads when Execution Providers fail to download.
