Presenting Gemma 3: The most advanced model that can operate on a single GPU or TPU.

Here’s the rewritten content with promotional call-to-actions mentioning external websites removed or rephrased:

<p>For a deeper dive into the technical details behind these capabilities, as well as a comprehensive overview of our approach to responsible development, refer to the Gemma 3 technical report.</p>

<h2>Rigorous safety protocols to build Gemma 3 responsibly</h2>
<p>We believe open models require careful risk assessment, and our approach balances innovation with safety – tailoring testing intensity to model capabilities. Gemma 3's development included extensive data governance, alignment with our safety policies via fine-tuning and robust benchmark evaluations. While thorough testing of more capable models often informs our assessment of less capable ones, Gemma 3's enhanced STEM performance prompted specific evaluations focused on its potential for misuse in creating harmful substances; their results indicate a low risk level.</p>

<p>As the industry develops more powerful models, it will be critical to collectively develop risk-proportionate approaches to safety. We will continue to learn and refine our safety practices for open models over time.</p>

<h2>Built-in safety for image applications with ShieldGemma 2</h2>
<p>Alongside Gemma 3, we're also launching ShieldGemma 2, a powerful 4B image safety checker built on the Gemma 3 foundation. ShieldGemma 2 provides a ready-made solution for image safety, outputting safety labels across three categories: dangerous content, sexually explicit, and violence. Developers can further customize ShieldGemma for their specific safety needs. ShieldGemma 2 is open and designed to provide flexibility and control, leveraging the performance and efficiency of the Gemma 3 architecture to promote responsible AI development.</p>
