FAQ
Can the NVIDIA RTX 3080 12GB run Granite 4.1 8B?

What's the best quantization to use?
Q8_0 is the highest-precision quantization that fits in your 12.0GB. It uses about 10.3GB of memory and 11.8GB 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.
