Updated: 2026-06-15

**No, not enough memory.** Needs ~10.8 GB even at Q4_K_M, but only ~8 GB is usable.

- Model: 14B, Q4_K_M 9.05 GB
- Device: 12 GB unified, ~8 GB usable for weights
- Needs ~10.8 GB at Q4_K_M; recommended quant: n/a
- Best tool on iOS: Apple Foundation Models

Estimate. Method: weights + KV cache + ~0.8GB overhead. Sources: https://ollama.com/library/phi4, https://ollama.com/library/phi4/tags, https://huggingface.co/bartowski/phi-4-GGUF, https://lmarena.ai/leaderboard.
