When Google released Gemini 3 Pro at the end of last year, it was a significant step forward for the company’s proprietary large language models. Now, the company is bringing some of the same technology and research that made those models possible to the open source community with the release of its new family of Gemma 4 open-weight models.
Google is offering four different versions of Gemma 4, differentiated by the number of parameters on offer. For edge devices, including smartphones, the company has the 2-billion and 4-billion “Effective” models. For more powerful machines, there’s the 26-billion “Mixture of Experts” and 31-billion “Dense” systems. For the unfamiliar, parameters are the settings a large language model can tweak to generate an output. Typically, models with more parameters will deliver better answers than ones with less, but running them also requires more powerful hardware.
With Gemma 4, Google claims it’s managed to engineer systems with “an unprecedented level of intelligence-per-parameter.” To back up this claim, the company points to the performance of Gemma 4’s 31-billion and 26-billion variants, which claimed the third and sixth spots respectively on Arena AI’s text leaderboard, beating out models 20 times their size.
All of the models can process video and images, making them ideal for tasks like optical character recognition. The two smaller models are also capable of processing audio inputs and understanding speech. Separately, Google says the Gemma 4 family is capable of generating offline code, meaning you could use them to do vibe coding without an internet connection. Google has also trained the models in more than 140 languages.
Google is releasing the Gemma 4 family under an Apache 2.0 license. The company made previous Gemma models available through its own Gemma license. The move will give people a greater deal of freedom to modify the new systems to their needs.
“This open-source license provides a foundation for complete developer flexibility and digital sovereignty; granting you complete control over your data, infrastructure and models.” Google said. “It allows you to build freely and deploy securely across any environment, whether on-premises or in the cloud.”
If you want to give one of the systems a try for yourself, the model weights are available through Hugging Face, Kaggle and Ollama.
