Responsiveness Optimization Guide
The following measures are suggested for the latency problem of real-time voice assistants:
- Preheat loading technology: Pre-execute empty text generation at program startup to trigger model compilation (Metal Shader optimization specific to M-series chips)
- Memory Residency Program: Declare csm objects as global variables to avoid time-consuming repeated model loading
- Streaming generation techniquesSet max_audio_length_ms=2000 for chunked generation, with real-time output in audiofile's append mode.
- Hardware-level optimization: Enable MLX's mlx.core.set_default_device('gpu') directive on M2 Max/Ultra devices
Monitoring suggestion: use mlx.core.memory_usage() to detect the video memory occupation in real time, when it exceeds 70% you need to clean up the history context array.
