Gemma 4 on Mac: Which Variant Fits Your Setup?

Gemma 4 on Apple Silicon: E2B, E4B, 26B or 31B — which model for which Mac.

Editorial method

Gemma 4 is Google’s current open model family. For Mac users, it’s interesting because the lineup ranges from tiny E2B to 31B Dense. But the question isn’t “what can the model do?” — it’s “what fits on my Mac?”

The short answer

8 GB Mac: gemma4:e2b (7.2 GB). Runs, but barely. More of an experiment than a daily driver.

16 GB Mac: gemma4:e4b (9.6 GB) is the sweet spot. Enough memory for everyday use, vision works, and context handles most tasks.

24-32 GB Mac: gemma4:26b (18 GB) — the MoE model with only 3.8B active parameters per token. Fast, efficient, and quality is surprisingly good for the activation rate.

48+ GB: gemma4:31b (20 GB). The full package with 31B dense parameters. More quality, but significantly more memory and slower token generation.

What I tested on my Mac Mini M4

I ran all variants on my 32 GB machine. Here’s what I noticed:

gemma4:e4b has become my daily driver. It runs fast, vision works reliably, and quality is enough for most coding and chat tasks. Memory usage is manageable — on 32 GB, plenty of room for other apps.

gemma4:26b is the quality-speed compromise. The MoE design means only 3.8B of 26B parameters activate per token. That makes it faster than a dense model of similar size. Runs well on 32 GB, but KV cache for long contexts grows quickly.

gemma4:31b is the full package. On 32 GB, it gets tight for longer contexts. On 48 GB, it’s the sweet spot for maximum quality. But honestly: the difference to 26b is smaller in practice than you’d expect.

Thinking Mode — when is it worth it?

Gemma 4 supports configurable thinking mode. The model “thinks” before answering — useful for math, logic, and multi-step planning. But it extends response time and uses more context.

My tip: Disable for quick everyday questions. Enable for complex coding tasks. The difference is noticeable — but not always worth the wait.

Ollama setup

ollama pull gemma4:e4b    # or 26b or 31b
ollama run gemma4:e4b

For vision, just pass an image:

ollama run gemma4:e4b "What do you see in this screenshot?"

The normal Ollama tags are listed as text+image. The *-mlx tags are text-only — only for the MLX alternative.

The 256K reality

26B and 31B support up to 256K tokens context. But that’s a model limit, not a promise. KV cache grows with context, and suddenly an 18 GB model needs 40+ GB. My tip: start at 8K, increase gradually, and check with ollama ps whether GPU offload is still complete.

Gemma 4 vs Qwen3

Qwen3 30B-A3B (MoE) is often faster on similar hardware and slightly ahead for coding. Gemma 4 excels at multimodal tasks (image+text) and has native Apple silicon optimization in MLX. For German, both are solid — Gemma 4 has slight advantages in grammar. Choose Qwen3 for coding, Gemma 4 for multimodal.

My verdict

Gemma 4 is the best open model family for serious local AI on Mac. The range from E2B to 31B means there’s a variant for every Mac.

My tip: Start with gemma4:e4b. If it’s too weak, upscale to 26b. That’s the fastest way to find the right variant for your workflow.
