Which Mac can run DeepSeek R1 Distill 32B?

Based on the recommended Q4_K_M quantization. You need RAM for both the model and your running apps — DevPulse calculates this for you. No CUDA installation. No driver hell. Just Apple Silicon doing what Jensen charges $30K for.

Tips for running DeepSeek R1 Distill 32B

1 MIT license — the most permissive option for a reasoning-focused 32B model

2 Chain-of-thought reasoning generates long outputs — watch memory during generation

3 On 32 GB Macs, use Q4_K_M and let DevPulse tell you what to close first

4 Best reasoning model you can run locally without a 64 GB machine

How fast will DeepSeek R1 Distill 32B run on each chip?

Apple Silicon inference is bandwidth-bound — every generated token streams the model's active weights through unified memory once. Estimates are for single-batch generation at Q4_K_M (19.0 GB) at ~70% of peak bandwidth (typical llama.cpp / Ollama efficiency). Speculative decoding can lift these another 30-60%.

Local-AI guides for DeepSeek R1 Distill 32B.

Knowing the model fits is half the problem. The other half is keeping your Mac's unified memory free enough to actually load it, and keeping the load alive across a long session.
