Updated: 2026-06-15

**Yes, but tight.** Fits at Q4_K_M (~28.9 GB of ~32 GB usable) but with little headroom, close other apps.

- Model: 46.7B (MoE, 12.9B active), Q4_K_M 26.49 GB
- Device: 48 GB unified, ~32 GB usable for weights
- Needs ~28.9 GB at Q4_K_M; recommended quant: Q4_K_M
- Best tool on macOS: LM Studio
- Command: `ollama run mixtral:8x7b`

Estimate. Method: weights + KV cache + ~0.8GB overhead. Sources: https://ollama.com/library/mixtral, https://ollama.com/library/mixtral/tags, https://huggingface.co/MaziyarPanahi/Mixtral-8x7B-Instruct-v0.1-GGUF, https://huggingface.co/mistralai/Mixtral-8x7B-Instruct-v0.1.
