FAQ
Can the NVIDIA RTX 5070 run Phi-4?
Yes. The NVIDIA RTX 5070's 12.0GB of VRAM is enough to run Phi-4 at Q5_K_M quantization (10.9GB required).
What's the best quantization to use?
Q5_K_M is the highest-precision quantization that fits in your 12.0GB. It uses about 10.9GB of memory and 12.4GB 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.
