No. Qwen 2.5 72B does not fit on M4 Max (32c GPU) 36GB: Q4_K_M needs 51.1 GB and 27.0 GB is usable.
Hardware: M4 Max (32c GPU) 36GB · Model: Qwen 2.5 72B
M4 Max (32c GPU) 36GB has 36 GB of unified memory and 410 GB/s of memory bandwidth. Mac Studio M4 Max (32c GPU) 36GB has the same memory and bandwidth, so the fit numbers match; this page is M4 Max (32c GPU) 36GB. The checker leaves macOS a share of unified memory, so Ollama can use 27.0 GB. Qwen 2.5 72B (72.7B, Alibaba) at Q4_K_M is a 47 GB download and needs 51.1 GB with headroom for about 8k tokens.
