Question 1

What's the difference between Gemma 4 and ChatGPT / Gemini?

Accepted Answer

Gemma 4 runs on YOUR hardware. ChatGPT and Gemini are cloud-only — your data goes to their servers. Gemma 4 is open-source (Apache 2.0), free forever, and works offline.

Question 2

My laptop has 8GB RAM. Which model can I run?

Accepted Answer

The E4B (4B parameter) model runs well on 8GB RAM. If you only have 4GB, try the E2B (2B) model. For 16GB+, the 26B MoE model offers the best balance of quality and speed.

Question 3

Can I use Gemma 4 in commercial projects?

Accepted Answer

Yes. Apache 2.0 license means zero restrictions. Use it in any commercial product, service, or application. No royalties, no attribution required.

Question 4

I don't know how to code. What's the easiest way to try?

Accepted Answer

Download LM Studio (free GUI app) — it's point-and-click, no terminal needed. Or try our playground above — just type and chat, nothing to install.

Question 5

Can Gemma 4 understand images and videos?

Accepted Answer

Yes! Gemma 4 is multimodal — you can send it photos, screenshots, charts, or video frames and it will describe and analyze them. Note: it understands images but doesn't generate them.

Question 6

Does the 256K context window really work locally?

Accepted Answer

The 256K limit is real, but using it locally requires massive RAM (22GB+ just for KV cache on the 31B model). For local use, 4K-8K context is most practical. Cloud deployments can use the full 256K.

Question 7

What's the difference between Gemma 4 and Gemma 3?

Accepted Answer

Key upgrades: Apache 2.0 license (was restricted), new MoE architecture (26B model), native audio input on small models, better benchmarks across the board. Worth upgrading.

Question 8

Can I run Gemma 4 on my phone?

Accepted Answer

Yes. The E2B (2B) model runs on modern phones. On iPhone, use the Google AI Edge Gallery app. On Android, use AICore or MediaPipe. It's slow but works completely offline.

Question 9

Yes. Gemma 4 natively supports 140+ languages including Chinese, Japanese, Korean, German, French, Arabic, and many more.
