FAQ
Can the AMD Instinct MI250X run Qwen 3.6 27B?

What's the best quantization to use?
fp16 is the highest-precision quantization that fits in your 128GB. It uses about 55.0GB of memory and 56.5GB 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.
