MediaTek renamed its AI block from APU to NPU at this generation. On-device LoRA training is the genuine first; the parameter ladder published a year earlier was not repeated, and its “>50 tokens” figure names no model or size, so it is not usable as a comparable specification.
MediaTek Dimensity 9400
First mobile chip with on-device LoRA training: the accelerator moved from inference-only to lightweight personalisation.
Silicon from MediaTek
