FAQ
Can the Apple M1 Ultra (128GB) run QwQ 32B?
Yes. The Apple M1 Ultra (128GB)'s 128GB of unified memory is enough to run QwQ 32B at fp16 quantization (65.0GB required).
What's the best quantization to use?
fp16 is the highest-precision quantization that fits in your 128GB. It uses about 65.0GB of memory and 66.5GB 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.
