Question 1

Is Gemma 4 free for commercial use?

Accepted Answer

Yes. Gemma 4 is released under the Apache 2.0 license, which means there are no commercial usage caps, no royalties, and no restrictions on how you deploy or modify the models. You can use them in production, sell products built on them, and fine-tune them without licensing fees.

Question 2

How does Gemma 4 compare to Gemini 3?

Accepted Answer

Gemma 4 is built from the same research as Gemini 3, but they serve different purposes. Gemini 3 is Google's proprietary, closed-API frontier model. Gemma 4 is the open-weight counterpart, designed for local and customizable deployment. If you need data sovereignty, offline edge computing, or full control over your model stack, Gemma 4 is the pick. Think of Gemma as the self-hosted sibling of Gemini.

Question 3

What is the "E" in Gemma 4 E2B?

Accepted Answer

It stands for "Effective." Using Per-Layer Embeddings (PLE), the E2B model acts with the intelligence of a 5B parameter model while maintaining a 2.3B active parameter footprint. This allows it to fit on mobile devices with less than 1.5 GB of available memory, without sacrificing reasoning quality.
