Gemma 2—Google DeepMind’s High-Performance Open Source LLM for Researchers and Developers

Google DeepMind’s Gemma 2 model sets a new standard for open source AI, offering 9B and 27B parameter versions with blazing-fast inference, high efficiency, and seamless integration with Hugging Face, TensorFlow, and more—tailored for both cutting-edge research and real-world applications.

Gemma 2, released in September 2025, is the latest family of open, state-of-the-art language models by Google DeepMind. Available in 9 billion and 27 billion parameter sizes, Gemma 2 delivers remarkable performance—even rivaling much larger models—while ensuring efficiency, safety, and broad compatibility for deployment across cloud and local hardware.

Key Features

• Model Sizes: 9B and 27B parameters for flexible deployment.
• Context Window: 8,000 tokens for long-document handling.
• Performance: 27B variant matches or exceeds models more than twice its size on multiple benchmarks; the 9B outperforms Llama 3 8B and similar models.
• Efficiency: The 27B model is optimized for single-card deployment on TPU hosts and NVIDIA A100/H100 GPUs, sharply reducing infrastructure costs.
• Open Source & Commercial Friendly: Released under the “Gemma License” (Apache 2.0 style) for research and commercial use, with weights and code available across platforms (Hugging Face, Google AI Studio, Kaggle).
• Safety & Transparency: Gemma 2 introduces ShieldGemma—an advanced safety classifier suite for moderation—and Gemma Scope for deep model interpretability, helping developers assess and enhance AI safety.
• Integration: Out-of-the-box compatibility with Hugging Face Transformers, TensorFlow (Keras 3.0), PyTorch, JAX, vLLM, Gemma.cpp, Ollama, and NVIDIA NeMo. Optimized for both cloud and local execution, including home computers with RTX GPUs.
• Deployment: Easy scaling via Google Vertex AI, Google AI Studio, or on-prem using quantized models.

How Gemma 2 Benefits Developers and Researchers
