Profiler
The EdgeFirst Profiler is the on-target measurement engine for the EdgeFirst Studio platform. It runs the complete vision pipeline — decode, preprocess, inference, postprocess, NMS — on the hardware your model will deploy to, then publishes per-image predictions and a detailed timing trace to EdgeFirst Studio where accuracy metrics, charts, and trace visualizations are produced.
For public benchmarks, explore the EdgeFirst Model Zoo on Hugging Face at https://huggingface.co/spaces/EdgeFirst/Models. We publish public benchmarks and metrics there across Ultralytics and other community models so you can compare your validation results against known baselines.
What it is
edgefirst-profiler is a native binary that runs on each supported target. It owns everything that has to happen next to the silicon: model loading, accelerated decode, pipeline orchestration, and the inference call itself. It uses edgefirst-hal under the hood for hardware-accelerated decode and pre/post-processing, drives every backend through a unified interface, and inherits the EdgeFirst DMA optimizations across the pipeline.
The result is a small, portable, high-performance on-target tool. Adding a new device to the EdgeFirst ecosystem only requires landing the profiler on that platform — the same CLI and workflow plug straight into the existing Studio-side metrics, charts, and reports.

The profiler measures and publishes. EdgeFirst Studio receives the artifacts and produces the accuracy charts, the per-operator timing visualizations, and the comparison views. The same v-XXXX validation-session ID links the on-target run to everything Studio shows afterwards.
What you can do with the profiler
The profiler is always operated against an EdgeFirst Studio session. There are two equivalent entry points:
- Validation from Studio — create a user-managed validation session in the Studio web UI, then run the profiler against that session ID on your target.
- Validation from the Profiler — browse training sessions inside the profiler's TUI and let the profiler create the validation session in place.
Both paths produce the same artifacts and the same Studio session card.
