• M4 with 16GB: Qwen 3 8B, Llama 4 8B, Mistral 7B
• M4 with 24GB: Qwen 3 14B, Gemma 2 27B (Q4)
• M4 Pro with 32GB: Qwen 3 30B, DeepSeek 33B
• M4 Max with 64GB: Qwen 3 72B, Llama 4 Scout

Best Models by RAM Tier

8GB Mac M4 (MacBook Air Base)

Model	Quality	Speed	Notes
Qwen 3 4B	⭐⭐⭐	Fast	Best for 8GB
Phi-3 Mini (3.8B)	⭐⭐⭐	Fast	Microsoft’s small model
Gemma 2 2B	⭐⭐	Very Fast	Good for testing

Reality check: 8GB is limiting. Contexts are short, complex tasks struggle. Consider 16GB minimum for serious use.

CodeLlama 13B	⭐⭐⭐⭐	Good	~9GB
Gemma 2 9B	⭐⭐⭐⭐	Very Good	~7GB

Sweet spot: 24GB lets you run models that 16GB cannot load.

32GB Mac M4 Pro/Max

Model	Quality	Speed	RAM Used
Qwen 3 30B (Q4_K_M)	⭐⭐⭐⭐⭐	Good	~20GB
Mixtral 8x7B	⭐⭐⭐⭐⭐	Moderate	~26GB
Llama 4 70B (Q2)	⭐⭐⭐⭐	Slow	~28GB

Best value: 32GB Mac Mini M4 is the sweet spot for serious local LLM use.

64GB Mac M4 Max

Model	Quality	Speed	RAM Used
Qwen 3 72B (Q4)	⭐⭐⭐⭐⭐	Moderate	~45GB
DeepSeek V4 67B	⭐⭐⭐⭐⭐	Moderate	~42GB
Llama 4 70B (Q4)	⭐⭐⭐⭐⭐	Moderate	~45GB

Near-frontier quality: 72B models approach Claude Sonnet quality for many tasks.

128GB+ Mac Studio M4 Ultra

Model	Quality	Speed	RAM Used
Llama 4 Scout (109B MoE)	⭐⭐⭐⭐⭐	Moderate	~70GB
DeepSeek V4 236B (Q2)	⭐⭐⭐⭐⭐	Slow	~100GB

Frontier territory: These compete with cloud APIs.

Mac Mini M4 as LLM Server

From starmorph.com’s guide (February 2026):

“The best value play for serious local LLM use. 32GB lets you run models that a 16GB machine simply cannot load. You can squeeze a 70B model at aggressive quantization, or run 14B–32B models comfortably at Q4.”

Recommended setup for small teams:

• Mac Mini M4 Pro 32GB: $1,599
• Running Qwen 3 30B
• Serve via Ollama API
• 2-5 concurrent users

How to Get Started

1. Install Ollama

brew install ollama

2. Pull a Model

ollama pull qwen3:8b

3. Run It

ollama run qwen3:8b

4. (Optional) Connect to an IDE

• Install Continue extension in VS Code
• Point to localhost:11434

M4 vs M3 vs M2 for LLMs

Chip	Memory Bandwidth	Tokens/sec (8B)	Best For
M4	120 GB/s	~35 tok/s	Current sweet spot
M4 Pro	200 GB/s	~55 tok/s	Power users
M4 Max	400 GB/s	~90 tok/s	Professional use
M3	100 GB/s	~30 tok/s	Still good
M2	100 GB/s	~28 tok/s	Budget option

M4’s improved Neural Engine and memory bandwidth make noticeable improvements.

FAQ

What’s the best model for 16GB Mac M4?

Qwen 3 8B (Q4_K_M quantization). It offers the best balance of quality, speed, and memory usage. Download via ollama pull qwen3:8b.

Can I run 70B models on 32GB Mac?

Barely. You’d need Q2 quantization which significantly reduces quality. For good 70B inference, get 64GB RAM.

Is Mac M4 good for local LLMs?

Yes, excellent. The unified memory architecture means models can use all your RAM as VRAM. M4’s improved Neural Engine helps too. Mac Mini M4 32GB is the current price/performance king for local inference.
