Updated: 2026-06-15

**Yes, but tight.** Fits at Q4_K_M (~7.3 GB of ~8 GB usable) but with little headroom, close other apps.

- Model: 9B, Q4_K_M 5.76 GB
- Device: 12 GB unified, ~8 GB usable for weights
- Needs ~7.3 GB at Q4_K_M; recommended quant: Q4_K_M
- Best tool on iOS: Apple Foundation Models

Estimate. Method: weights + KV cache + ~0.8GB overhead. Sources: https://ollama.com/library/gemma2, https://ollama.com/library/gemma2/tags, https://huggingface.co/bartowski/gemma-2-9b-it-GGUF, https://lmarena.ai/leaderboard.
