Google has released the Gemma 4 open-source AI model, which comes in four sizes: Effective 2B, Effective 4B, 26B MoE, and 31B Dense. It is accessible under the Apache 2.0 licence. Gemma 4 can plan multi-step and use deep logic. It has been trained on more than 140 languages. It has better agentic skills and advanced reasoning than Gemma 3, its predecessor.
Google has announced Gemma 4, their most advanced open models. These models improve reasoning and agentic workflows. This version has a very high intelligence per parameter, shows a lot of technical progress, and has a lot of community support, as seen by the fact that preceding versions have been downloaded over 400 million times. The ecosystem also has a changing “Gemmaverse” with more than 100,000 developer-created versions that meet the demands of innovators. It is available under an Apache 2.0 licence.
Gemma 4 has four model sizes: Effective 2B (E2B), Effective 4B (E4B), 26B Mixture of Experts (MoE), and 31B Dense. These models go from basic chat functionality to advanced logical thinking and agentic tasks. On the Arena AI text leaderboard, the 31B model ranks third, while the 26B model ranks sixth, outperforming the competition 20 times bigger. The inclusion of intelligence-per-parameter offers high-level capabilities while reducing hardware requirements. Furthermore, the E2B and E4B models emphasise on-device usage, multimodal functionality, low-latency processing, and seamless integration with a variety of systems.
Gemma 4 versions are optimised for performance on a variety of hardware platforms, including Android smartphones, laptop GPUs, and developer workstations. They may be tailored to particular purposes, showcasing effectiveness in projects like BgGPT and collaborations with Yale University on cancer therapy research. Gemma 4’s notable features include advanced reasoning abilities for improved multi-step planning and logic problem solving, agentic workflows that facilitate function calling and structured JSON output for developing autonomous agents, and code generation functions that transform workstations into AI coding assistants capable of producing high-quality offline code. These models also have native vision and audio processing, which allows them to handle video, picture, and speech recognition tasks well. They offer longer context windows, with edge versions handling up to 128K tokens and bigger models allowing up to 256K tokens, increasing processing capability for long-form content. Furthermore, Gemma 4 models support over 140 languages, enabling the development of inclusive applications on a worldwide scale.

The Gemma 4 model weights have been released in tailored variants for certain hardware and use cases, including 26B and 31B models suited for offline usage on personal computers. The unquantised bfloat16 weights are designed to fit on a single 80GB NVIDIA H100 GPU, while quantised versions are available for consumer GPUs to enhance integrated development environments (IDEs), coding assistants, and workflows. The 26B Mixture of Experts (MoE) model activates 3.8 billion parameters during inference to improve performance, while the 31B Dense model prioritises quality and is suited for fine-tuning. Furthermore, the E2B and E4B models are optimised for mobile and IoT devices, with 2 billion and 4 billion parameters enabled during inference to save RAM and battery life. This development involved collaboration with Google Pixel and hardware industry heavyweights like Qualcomm and MediaTek. The multimodal models run offline with almost no latency on devices like phones and Raspberry Pi, and Android developers may use the AICore Developer Preview to prototype compatibility with Gemini Nano 4.

Gemma 4 is a robust model made for enterprises and organisations that follow strict security protocols similar to those of proprietary systems. This makes it very secure and reliable. Users may quickly interact with Gemma 4 via tools like Google AI Studio or Google AI Edge Gallery, which provide different setups. The model works with a lot of different tools, such as Hugging Face and the ML Kit GenAI Prompt API, which gives developers a lot of freedom. People may acquire model weights from sites like Hugging Face, Kaggle, or Ollama. They can also use Google Colab or Vertex AI to make Gemma 4 fit their requirements. Vertex AI and TPU-accelerated serving are two Google Cloud services that make production more scalable. These are important for workloads that have to follow guidelines. The model is also optimised for performance on a variety of hardware, such as NVIDIA AI, AMD GPUs, and TPUs. Finally, projects like the Gemma 4 Good Challenge on Kaggle get people involved in making products that will have a beneficial effect on the community.
