Akros · Accuracy
We measure ourselves in public.
Akros has the benchmark harness for measured food-photo accuracy, but no public Akros MAE is published until source-tracked image rows, ground-truth weights, and Akros estimates are attached. We do not run head-to-head comparisons against competitors that do not publish per-meal data; we cite their published ranges instead.
This week’s Akros runs
No Akros food-photo accuracy number is published yet.
The launch gate requires at least 25 source-tracked meal images with measured ground truth and Akros estimates before this table can show an Akros MAE. Synthetic contract rows and USDA/FNDDS ground-truth rows validate the harness, but they are not public photo-accuracy evidence.
Published competitor ranges
We do not fabricate Cal AI vs Akros per-meal comparisons because Cal AI does not expose per-meal accuracy data. Below are the figures each competitor (or independent reviewer) has published — sourced and linked.
- Cal AI20–50% MAELifehacker independent test, 2024
- MacroFactor~9.4% MAEMacroFactor published accuracy whitepaper
- SnapCalorie~16% MAESnapCalorie published validation
How we run the benchmark
The benchmark runner accepts source-tracked meal images, measured kcal/macros, and the same food-photo endpoint your iPhone calls. It records returned macros, latency, p50/p95 kcal error, macro error, and row-level failures against the labelled truth.
Only measured rows with image provenance and attached Akros estimates can be published here. We refuse to scrub failed rows from a published run. If a release regresses accuracy, the next row should make it visible before we tell ourselves it is fine.
