No — not on this device
LLM-jp 4 33B Thinking at Q4_K_M needs 21.3 GB against 18.0 GB usable, and the shortfall of 3.3 GB is more than 64 GB of system RAM can cover at a tolerable speed. A smaller sibling or a lower quantisation is the honest answer here.

Quantisation ladder
| Quant | Weights | Total @ 8K | Max context | Tok/s | Quality | Fit |
|---|---|---|---|---|---|---|
| Q8_0 | 32.9 GB | 35.5 GB | — | ~1.7 | −0.1% ppl | 17.5 GB over |
| Q6_K | 25.4 GB | 28.0 GB | — | ~2.2 | −0.4% ppl | 10.0 GB over |

| Q4_K_M | 18.7 GB | 21.3 GB | — | ~3.0 | −1.9% ppl | 3.3 GB over |

Quality is the published perplexity delta against f16 weights. Max context assumes an f16 KV cache; q8_0 roughly doubles it.
How to run it
$ pip install mlx-lm $ mlx_lm.generate --model mlx-community/llm-jp-4-33b-thinking-4bit \ --max-tokens 512 --prompt "Hello"

01Download is 18.7 GB. Keep it on an SSD — a first load off a spinning disk takes minutes.
02macOS caps what the GPU may wire down at about 18.0 GB of 24 GB. Raising it with iogpu.wired_limit_mb is possible, and risky.
03If it falls back to CPU silently, drop the context first, then step down a quantisation.
