  • It features an expanded context window of 128K tokens, allowing it to handle large datasets and complex AI tasks more efficiently than previous versions.

2. Safety and Responsible AI

  • The model integrates ShieldGemma 2, an advanced image safety classifier that filters out explicit, violent, or inappropriate content, ensuring ethical AI usage.

3. Multilingual Support

  • Gemma 3 supports over 140 languages, making it ideal for global AI applications, including translation, multilingual chatbots, and international content creation.

4. Optimized for AI Development

  • Gemma 3 is available on Hugging Face’s Transformers library, Keras (with a JAX backend), and Ollama, providing flexibility for developers across various frameworks.
  • The model is designed for fine-tuning with LoRA (Low-Rank Adaptation) and supports model-parallelism distributed training on TPUs (Tensor Processing Units).

Evolution of the Gemma Series

1. Early Gemma Models

The first Gemma models were released in February 2024, with versions optimized for:

  • GPU and TPU (7 billion parameters) for high-performance AI tasks.
  • CPU and on-device AI (2 billion parameters) for mobile and embedded applications.

These models were trained on up to 6 trillion tokens of text, incorporating methodologies from Google’s Gemini model set.

2. Gemma 2 and PaliGemma 2

  • June 2024: Gemma 2 models were released, offering enhanced efficiency and new multimodal capabilities.
  • December 2024: PaliGemma 2, an upgraded vision-language model, was introduced for AI-driven image and text understanding.

3. Gemma 3 and PaliGemma 2 Mix

  • February 2025: Google launched PaliGemma 2 Mix, optimized for multiple tasks and available in 3B, 10B, and 28B parameter configurations with 224px and 448px resolutions.
  • Mid-2025: Gemma 3 was introduced as the most advanced iteration, integrating multimodal AI capabilities with a focus on scalability and efficiency.

Advantages
