Visual Guide to Gemma 4

Google has unveiled the Gemma 4 family, a significant expansion of its open-weight AI model offerings. The release includes four distinct model sizes: a lightweight 2B-parameter version for on-device use, a 9B model, a 72B model, and a flagship 405B-parameter model. This 405B variant, named Gemma 4:405B, is positioned as a direct competitor to leading closed-source models such as OpenAI's GPT-4o and Anthropic's Claude 3.5 Sonnet, marking a major step in making state-of-the-art capabilities accessible under open licenses.

All models in the Gemma 4 family are released with open weights, allowing developers to download, run, and fine-tune them for commercial and research purposes. The scaled architecture is designed for efficiency across the board, with the smaller models targeting edge deployment and the massive 405B model aiming for top-tier reasoning and coding performance. This strategic release provides the developer community with a powerful, customizable alternative to proprietary APIs, potentially accelerating innovation in agentic systems, code generation, and enterprise AI applications.
