What's the best quantization to use?
f32 is the highest-precision quantization that fits in your 512GB. It uses about 478.6GB of memory and 480.1GB 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.
