Work bought me three 512gb Mac Studio M3 Ultras (one for my desktop and two for my lab). I run exo on two of them and can dang near run any model I want if I can find one that runs on the hardware (DeepSeek-v4-flash has been problematic so far). I’m so glad I got them before the prices skyrocketed. Hell I think they even stopped making the 512gb version completely.
