AI on this rack

AI on this rack chart: 1TB unified memory, 819GB/s memory bandwidth per Mac, a 120Gb/s Thunderbolt 5 link, and the peak memory and speed of the models it runs

With 512GB in each Mac, this rack runs everything a single Mac Studio runs, plus the largest models we list. Measured on two Mac Studios with this configuration:

  • GLM-5.3: 463GB peak memory on each Mac, 20 tokens per second
  • DeepSeek V4.1 Flash: 285GB peak memory on each Mac, 34 tokens per second

Built for Izuran Pro

Izuran Pro is our own server software. It splits one model across both Macs and serves it to your team on your network, on our fork of Apple's MLX. You download your models inside Izuran Pro, and it copies them to both Macs. About Izuran

Where to put it

  • Size: about 11 x 7.8 x 16 inches (28 x 20 x 41 cm), small enough to sit on a desk
  • Room: keep it between 50 and 95°F (10 to 35°C)
  • Airflow: keep the back at least 4 inches from a wall, and leave the side panels on
  • Power: each Mac Studio is rated for up to 480W of continuous power, so use a circuit without other heavy loads

Before delivery

Both Macs are erased, with Activation Lock and remote management off. Then we install Izuran Pro and set them up as a cluster, with automatic login on and FileVault off so the rack starts by itself after a power cut. If you need FileVault on, tell us in your request. Someone will then need to sign in after each restart.
