FAQ

Can the NVIDIA RTX 3080 10GB run Phi-4?

Yes. The NVIDIA RTX 3080 10GB's 10.0GB of VRAM is enough to run Phi-4 at Q4_K_M quantization (9.9GB required).

What's the best quantization to use?

Q4_K_M is the highest-precision quantization that fits in your 10.0GB. It uses about 9.9GB of memory and 11.4GB 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.
