About this paper

Andrew Geyko, Marius Mosbach, André Brinkmann

The authors measure on-device fine-tuning of per-user adapters on an iPhone 17 Pro and repair an MLX kernel for the frozen model’s backward pass. The repaired kernel cuts the 405-record run from 2.55 hours to 1.74 hours and energy from 39.3 to 26.2 kJ. On movie tagging, phone- and server-trained adapters score 0.486 and 0.488, in one task and protocol.
