AI Model Calculator

Pick a model and see which of our dedicated Apple Silicon Macs can run it, how much memory it needs, and roughly how fast it will answer.

Try it live

Ask a question and watch a model answer in real time on our Mac Studio M4 Max 128GB in our datacenter. 50 free questions per hour.

Demo answers come straight from the model and may be wrong. Questions aren't saved. Want to ask follow-up questions? Open the full live chat →

How we estimate

  • Memory: model weights at the chosen precision, plus the context (KV) cache and runtime overhead. We leave about 10% of each Mac's memory for macOS.
  • Speed: generating text on Apple Silicon is limited by memory bandwidth. We use Apple's published bandwidth for each chip, real-world efficiency of 45–65% (llama.cpp / MLX), and a small fixed cost per token. Mixture-of-experts (MoE) models only read their active experts, so they run much faster than their size suggests.
  • Our hardware: every Mac we offer is the top configuration of its chip, with the most CPU and GPU cores.
  • Clusters: the model's layers are split across Macs linked over Thunderbolt 5, so memory adds up while speed stays close to a single Mac's.
  • Results are estimates. Prompt processing, batch size and software choice all affect real speed. Ask us if you want a benchmark on a specific machine.
