Google Unleashes Gemma 4 with a Game-Changing Open Source Shift

Google has announced the release of Gemma 4, representing the first major update to its open model family in a year. Beyond the performance improvements inherent in the new generation, the most significant change is the switch to the Apache 2.0 license, which provides a more permissive legal framework for developers to use and redistribute the models. This move is designed to accelerate AI innovation by making high-quality language models more accessible and easier to integrate into commercial and research projects without the previous licensing hurdles.
