FAQ
Can the NVIDIA GTX 1650 run Phi-4 Mini?
Yes. The NVIDIA GTX 1650's 4.0GB of VRAM is enough to run Phi-4 Mini at Q5_K_M quantization (3.7GB required).
What's the best quantization to use?
Q5_K_M is the highest-precision quantization that fits in your 4.0GB. It uses about 3.7GB of memory and 5.2GB 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.
