Google has officially released Gemma 4, its latest and most intelligent open-source AI model family. The company launched it on April 2, 2026.

Gemma 4 is built using the same advanced research and technology as Google’s powerful Gemini 3 model. It is designed to perform complex thinking, reasoning, and “agentic” tasks (tasks where AI can act on its own, like using tools and planning steps).

Main Highlights of Gemma 4

• Fully Open Source: Gemma 4 comes with a very friendly Apache 2.0 license. This means anyone can use it freely, even for commercial purposes.

• Four Different Sizes: Google released four versions so it can run on different devices:
  • E2B (small, fast for phones and edge devices)
  • E4B (slightly bigger and more capable)
  • 26B MoE (Mixture of Experts – good balance of speed and power)
  • 31B Dense (largest and most powerful version)

• Strong Capabilities:
  • Advanced reasoning and problem-solving
  • Can understand text, images, and audio (multimodal)
  • Supports up to 256,000 tokens context window (very long memory)
  • Works in over 140 languages
  • Excellent at coding, planning, and using tools

• Runs Locally: You can run Gemma 4 on your own computer, laptop, or even mobile devices without sending data to the cloud.

Many big AI companies keep their best models closed. Google is making Gemma 4 fully open so developers, researchers, and companies around the world can use it, modify it, and build new applications on top of it.

It is especially useful for:

• Running AI on phones and laptops (on-device AI)
• Building smart agents that can do tasks automatically
• Coding assistance
• Privacy-focused applications (data stays on your device)

You can start using Gemma 4 right now on:

• Google AI Studio
• Hugging Face
• Kaggle
• Ollama
• Google Cloud

Developers can also download the full model weights and fine-tune them for their own needs.

With Gemma 4, Google has made very powerful AI technology available to everyone. It brings advanced reasoning and tool-using abilities that were previously only available in closed models.

This release is a big step for open AI development. Many experts believe Gemma 4 will help speed up innovation in the AI community.
