L got into LLM world not while ago and the first thing I did was to buy Mac Studio M3 Ultra with 512GB (thank god I managed to buy it before the configuration not available anymore). soon as I got it I rushed to install OpenCode and the just-released Qwen3.5 series with all the amazing hype around it. I ran serval real world tasks that require architecture, coding and debugging. as a newbie, I read that MLX models are optimized for Apple silicon cheap and promised me the wonderful benefits of the silicon architecture.
