Google just released the latest version of its open AI model, Gemma 4, on Thursday. Crucially, Gemma 4 is a fully open-source model licensed under Apache 2.0, which is typically not the case with frontier models.

Open models can be run locally on users' devices, and Google says Gemma 4 can be run on "billions of Android devices" and some laptop GPUs.

"This open-source license provides a foundation for complete developer flexibility and digital sovereignty; granting you complete control over your data, infrastructure, and models," a Google blog post reads. "It allows you to build freely and deploy securely across any environment, whether on-premises or in the cloud."

Most people have likely heard of Google's popular Gemini AI model, thanks to the ubiquitous AI chatbot that's been integrated into many of Google's products.

Gemma is also a large language model (LLM) and was developed from the exact same technology and research that Google DeepMind used to build Gemini 3.

Google is calling Gemma 4 its "most capable" open AI model yet.
