Bringing Visual Graph Debugging to Custom Edge Compilers with Model Explorer- Google Developers Blog

Arm integrated custom compiler Intermediate Representations (IRs) like TOSA, VGF, and PTE into Google AI Edge Model Explorer. This enables visual debugging of on-device ML model pipelines, including validation of exported graphs (e.g., catching unintended TRANSPOSE operators in VGF), side-by-side comparison of CPU vs. NPU delegation using split-pane view for models like Ultralytics YOLO, and pinpointing cycle-level bottlenecks by overlaying execution traces onto the graph.
