Can I run it?
Can I run GLM 4.7 Flash on Apple M1 Max?
Tight fit
Tight fit fully in unified memory on your Apple M1 Max at UD-Q5_K_XL, 8K context, about 24–32 tok/s. Weights 20.2 GB plus 0.41 GB of KV cache — 21.1 GB of 24.0 GB usable. Up to 32K context still fits.

Assumptions
- Estimate from memory bandwidth, not a benchmark. Decode speed uses 55–75% of peak bandwidth.
- KV cache is FP16. Engine overhead assumes llama.cpp (0.3 GB + 1% of the weights). Ollama is closer to 0.9 GB + 3%, LM Studio closer to 1 GB + 3%.
- UD-Q5_K_XL size is the real GGUF file size from Hugging Face.
- Unified memory uses 75% for the GPU by default, and always leaves about 5 GB for the OS.
- Speed is quoted at 8K context, not at the maximum context that still fits.
