FAQ
Can the Apple M5 Ultra (512GB) run DeepSeek V3.2?
Yes. The Apple M5 Ultra (512GB)'s 512GB of unified memory is enough to run DeepSeek V3.2 at Q5_K_M quantization (487.4GB required).
What's the best quantization to use?
Q5_K_M is the highest-precision quantization that fits in your 512GB. It uses about 487.4GB of memory and 488.9GB 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.
