Phi-4 Family — Frequently Asked Questions

How much VRAM does Phi-4 Family need?

Phi-4 Family needs about 9 GB VRAM at Q4_K_M quantization for its smallest variant. Variants: Phi-4 (14B) (9 GB, Q4_K_M). On Apple Silicon, unified memory counts toward this requirement.

Can I run Phi-4 Family on an RTX 4090 (24 GB)?

Yes — Phi-4 Family runs on an RTX 4090 (24 GB) and other 24 GB cards such as the RTX 3090. Smaller variants also fit comfortably on 8–16 GB GPUs at Q4_K_M.

What quantization should I use for Phi-4 Family?

Q4_K_M is the best balance of quality and VRAM for Phi-4 Family in most cases. Choose Q8_0 for near-lossless quality if you have spare VRAM, or smaller quants (Q3/Q2) only when memory is tight.

How do I run Phi-4 Family with Ollama?

Install Ollama, then run: ollama run phi4. This downloads Phi-4 Family and starts a local, OpenAI-compatible endpoint — no internet connection is needed after the initial download.
