Question 2

What quantization of DeepSeek R1 Distill Qwen 1.5B should I use on a Apple M4 Max?

Accepted Answer

For 128 GB VRAM on the Apple M4 Max, the Q8_0 variant is the best fit. Estimated ~325 tokens/sec on the Q8_0 quantization.

Question 3

How fast does DeepSeek R1 Distill Qwen 1.5B run on Apple M4 Max?

Accepted Answer

Roughly 325 tokens/sec for Q8_0. Real speed depends on context length, backend (Ollama, llama.cpp, LM Studio), and KV cache size.

Question 4

What if Apple M4 Max is not enough for DeepSeek R1 Distill Qwen 1.5B?

Accepted Answer

Try a smaller quantization variant or run on CPU + RAM with the trade-off of slower generation.

Quantization	File Size	Min VRAM	Rec VRAM	Context	Verdict	Estimated tok/s
Q4_K_M	1 GB	2 GB	4 GB	8K / 128K	Full GPU	~436.8
