What can you run with 64GB of RAM?
With 64GB RAM you can run 32 of the 66 open-source models we track, up to 74B parameters, using each model's Q4 file where one is published and otherwise the smallest file that is. The most downloaded that fits is Qwen3.8-27B, needing 19 GB.
Typical machines: MacBook Pro M5 Max (64GB) · Mac Studio M5 Max (64GB) · Mac mini M5 Pro (64GB). We hold back 20% of RAM (2 to 4GB) for the operating system, leaving 64 GB for a model.
64GB RAM decides whether a model loads. How fast it answers depends on your machine's memory bandwidth, which differs between machines with the same amount of memory. Why bandwidth sets the speed →

Step up to 128GB RAM and 5 more models come within reach
Including Laguna-S-2.1 (118B), Ornith-1.5-122B (125B) and Ling-3.0-flash-VL (125B).
See everything 128GB RAM runs →All figures at Q4_K_M quantization and 4K context. “Memory” is the model's download size from Hugging Face, plus its context cache calculated from the model's configuration, plus a runtime allowance of 10% of the model (at least 0.5GB, at most 3GB). How this is calculated
Image generators that also fit
These make pictures rather than text. Their memory use scales with the resolution you generate at, not conversation length, so treat these figures as a floor rather than a ceiling.
