Apple wins the AI infra lottery: M5 Ultra packs 512GB unified memory for local AI
Hesamation · x · 2026-09-21
- M5 Ultra Mac Studio ships with up to 512GB unified memory and is now positioned as a local AI workstation; MKBHD, after a week of use, calls it the most powerful local-AI machine, noting Apple's site has pivoted from 3D/video workflows to local AI use cases.
- Ecosystem facts: OpenAI bought tens of thousands of Macs for RL, Anthropic rents Macs via AWS, and Apple itself demos running Kimi locally on M5 Ultra.
- The author argues Apple has quietly won the local inference entry point, though real-world Kimi-on-M5 demos are still awaited.
