Updated: 2026-06-15

**No, not enough memory.** Needs ~50.2 GB even at Q4_K_M, but only ~4.5 GB is usable.

- Model: 72B, Q4_K_M 47.42 GB
- Device: 8 GB unified, ~4.5 GB usable for weights
- Needs ~50.2 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/qwen2.5, https://huggingface.co/bartowski/Qwen2.5-72B-Instruct-GGUF, https://qwenlm.github.io/blog/qwen2.5/, https://lmarena.ai/leaderboard.
