Updated: 2026-06-15

**No, not enough memory.** Needs ~45.3 GB even at Q4_K_M, but only ~16 GB is usable.

- Model: 70B, Q4_K_M 42.52 GB
- Device: 24 GB unified, ~16 GB usable for weights
- Needs ~45.3 GB at Q4_K_M; recommended quant: n/a
- Best tool on macOS: LM Studio
- Command: `ollama run llama3.3:70b`

Estimate. Method: weights + KV cache + ~0.8GB overhead. Sources: https://ollama.com/library/llama3.3, https://ollama.com/library/llama3.3/tags, https://huggingface.co/bartowski/Llama-3.3-70B-Instruct-GGUF, https://lmarena.ai/leaderboard.
