FAQ
Can the AMD Instinct MI300X run Qwen 3.5 Omni Plus?

What's the best quantization to use?
Q5_K_M is the highest-precision quantization that fits in your 192GB. It uses about 167.8GB of memory and 169.3GB 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.
