# Can I run Yi 1.5 34B on Apple M4 Pro (24GB)?

Updated: 2026-06-15

**No, not enough memory.** Needs ~21.4 GB even at Q4_K_M, but only ~16 GB is usable.

- Model: 34B, Q4_K_M 19.24 GB
- Device: 24 GB unified, ~16 GB usable for weights
- Needs ~21.4 GB at Q4_K_M; recommended quant: n/a
- Best tool on macOS: LM Studio

Estimate. Method: weights + KV cache + ~0.8GB overhead. Sources: https://huggingface.co/bartowski/Yi-1.5-34B-Chat-GGUF, https://huggingface.co/01-ai/Yi-1.5-34B-Chat.
