I have done over 500 training sessions using Qwen2.5, Qwen3, Gemma and plenty other LLM publicly available to inject domain specific knowledge into the model’s low rank adapters (LORA). However, instead of giving you tons of unimportant facts I will just stick to the most important things. Starting with the fact that I have used MLX on my Mac Studio M2 Ultra as well as on MacBook Pro M1 Pro. Both fit well to this task in terms of BF16 speed as well as unified memory capacity and speed (up to 800GB/s). Memory speed is the most important factor comparing
