Can Mac Studio M5 Max 128 GB run GLM-4.5-Air (106B-A12B)?

128 GB unified · 614 GB/s memory bandwidth · GLM-4.5-Air (106B-A12B) has 110.5B parameters (12B active per token).

Short answer

Yes, excellent for chat and acceptable or better for every workload we test.

Best quantization for chat: 5-bit (71 GB of weights) on LM Studio. Generation: 25–45 tok/s, leaving about 44 GB free for your other apps.

How it rates for each workload

Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.

Speeds are bandwidth-based estimates; no direct benchmark exists for this pair. “First reply” is the time to read the workload’s opening prompt. How we calculate

Get it running

Copy-paste commands for the 5-bit build with a 64K context. Ollama and llama.cpp download the file straight from Hugging Face.

ollama run hf.co/unsloth/GLM-4.5-Air-GGUF:Q5_K_M

This build is split into 2 files, which Ollama can't import from Hugging Face. Use llama.cpp or LM Studio instead.
