Can I run GLM 4.7 Flash on Apple M3 Pro?
Tight fit
Tight fit fully in unified memory on your Apple M3 Pro at UD-IQ3_XXS, 4K context, about 15–21 tok/s. Weights 12.0 GB plus 0.21 GB of KV cache — 12.6 GB of 13.0 GB usable.

Run commands

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-IQ3_XXS 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 4K context, not at the maximum context that still fits.
