FAQ
Can the Apple M2 Pro (32GB) run Qwen3 32B?
Yes. The Apple M2 Pro (32GB)'s 32.0GB of unified memory is enough to run Qwen3 32B at Q6_K quantization (28.0GB required).
What's the best quantization to use?
Q6_K is the highest-precision quantization that fits in your 32.0GB. It uses about 28.0GB of memory and 29.5GB recommended for comfortable inference.
What if I need more headroom for context length?
KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
