What can the 32B reasoning class solve that smaller distills cannot?
The gap is widest exactly where reasoning matters: competition-level math, multi-constraint planning, subtle logical traps. Smaller distills imitate the thinking style; the 32B tier actually sustains it across long derivations without losing the thread. The ~45GB budget also hosts the enormous thinking contexts these models burn.
Generation speed stays workable thanks to the Studio bandwidth, but expect minutes per hard problem. That is the nature of the approach, not a hardware limit. Run a fast chat model side-by-side and route only genuinely hard questions to the reasoner.

Frequently Asked Questions
What is the best reasoning model for Mac Studio?
With 64GB RAM, Qwen3.5 35B-A3B Instruct is the best reasoning model for Mac Studio. It fits within the 45GB memory budget and delivers the highest quality for reasoning tasks. Run it with: ollama run qwen3.5:35b-a3b
Is the 32B reasoning tier worth a Mac Studio over the 14B class?
If you bring it hard problems, yes: sustained derivations, planning with many constraints, math beyond textbook level. For everyday step-by-step explanations, the 14B distills on a cheaper machine cover most of the value.
How much context do big reasoning models really use?
A lot. A hard problem can produce tens of thousands of thinking tokens before the answer, all held in memory. The 64GB Studio absorbs this; on smaller machines the same model would truncate its own reasoning.
