Feb 1, 2025February 2025 monthly summary for tenstorrent/tt-metal: Implemented YOLOv4 Performance Timing Utilities to enable repeatable compile-time and inference-time measurements, supporting robust performance testing and optimization planning. These utilities provide expected timing baselines to accelerate benchmarking and decision-making for model deployment. In addition, two commits fixed pre-commit issues in the YOLO performance code to maintain CI reliability and prevent validation blockers during the feature rollout.
