## Performance

## Browser (LiteRT.js)

Model-level sweep results — measured behavior of this exact `.tflite` in the browser, only meaningful together with the environment that produced it. Full records (failure class, error evidence, sweep config): `data/sweep/2.5.3/2026-08-11/clipseg-rd64__clipseg_text_fp16.json`.

## Device runs (NPU / LiteRT-LM)

Model-level on-device results — measured behavior of this exact artifact on the recorded device, only meaningful together with that environment. Throughput is conditional on the measured prompt length (Prompt (tokens); '-' = the source stated none): rows differing only there are different measurements, not re-runs. Full records (failure classes, log evidence): `data/device_runs/2.2.0.dev20260804/2026-08-31/clipseg-rd64__clipseg_text_fp16__raspberry-pi-5.json`, `data/device_runs/2.2.0/2026-08-26/clipseg-rd64__clipseg_text_fp16__galaxy-s26.json`.
