What’s new in Gemma 4?

We are thrilled to announce Gemma 4. Built from the same world-class research and technology behind Gemini 3, Gemma 4 is a family of open models designed to run directly on the hardware you own: phone, laptops, and desktop. For the first time ever, we're releasing Gemma under an open-source Apache 2. 0 license. Gemma 4 is built for the agentic era. It can handle complex logic, multi-step planning, and agentic workflows, making optimal use of tokens for its intelligence. The bigger model perform well with a context window of up to 1/4 million tokens, allowing you to analyze entire code bases, and all multi-turn agentic use cases. It features native support for tool use, allowing you to build agents that plan and act on your behalf. Let's break down the model family now. First, a 26B mixture of experts and a 31B dense models. These provide frontier intelligence directly on your personal computer. You can run state-of-the-art local reasoning and coding pipeline without needing to upload data outside of your control environment. The 26B MoE with 3. 8 billion activated parameters is exceptionally fast, while 31B is optimized for output quality. Then, we have our effective 2B and effective 4B models. Engineered for maximum memory efficiency, these models bring a whole new level of intelligence to mobile and IoT devices. With combined audio and vision support for real-time processing, they can see and hear the world. All of this while natively supporting over 140 languages. Now, let's test our effective 2B on multilingual and agentic tasks. Hey, Gemma. Est-ce que tu peux trouver un restaurant français à San? Please reply to me in English. Amazing, we have a winner. As open models become more central to enterprise infrastructure, security is paramount. Developed by Google DeepMind, Gemma 4 undergoes the same rigorous security protocols — as our proprietary models, giving enterprise and developer a trusted foundation to build on top of. We want you to be able to use Gemma 4 with the tools you already know and love. You can download the weights and start experimenting today. We cannot wait to see what you create next.
