Can I run Qwen3.5 35B A3B on Apple M5 Pro?
Tight fit
Tight fit fully in unified memory on your Apple M5 Pro at UD-IQ4_XS, 8K context, about 23–32 tok/s. Weights 16.3 GB plus 0.19 GB of KV cache — 16.9 GB of 18.0 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-IQ4_XS 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.
