Open-source deadlift form checker chains SAM 3.1, ViTPose+ and Gemma 4
spillai · x · 2026-10-01
Developer jeremyparkphd open-sourced a computer vision tool for evaluating deadlift form, chained via the @vlmrun Gateway:
- SAM 3.1 segments the barbell weight plate to count reps;
- ViTPose+ Large measures the hip hinge angle as a backup rep signal, with pose data left for future use;
- Gemma 4 26B outputs the probability of a rounded back through the Gateway's TypeSafe-compatible API.
Predictions lined up well with reps the author intentionally performed well or badly. The tool gives lifters quantitative data to track and improve form, and each module can be quickly adapted to individual differences. Code is open-sourced.
