Benchmarks & Profiling
Deterministic latency and VRAM allocation statistics
Physical mobile verification was completed on Samsung Galaxy S21 5G (Samsung Exynos 2100 / ARM Mali-G78 MP14) on native Android 14 Termux Bionic libc. Total GPU allocation was strictly capped at 1.0 GB VRAM via dynamic layer streaming, achieving 100% convergence with zero memory crashes (OOM Zero).
