FAQ
Can the Apple M2 Max (96GB) run Gemma 4 31B?
Yes. The Apple M2 Max (96GB)'s 96.0GB of unified memory is enough to run Gemma 4 31B at fp16 quantization (63.6GB required).
What's the best quantization to use?
fp16 is the highest-precision quantization that fits in your 96.0GB. It uses about 63.6GB of memory and 65.1GB 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.
