Dont be Fooled by Google Gemmas Openness [Video]

Before you assume that Google has finally embraced the open-source route, let us clear the air – Gemma is not an open-source model; it is an ‘open-model’ and there is a huge difference between the two.

In the official blog post of Google Gemma, the company has strategically called it “a family of lightweight, state-of-the-art open models”. These models are said to be built from the same research and technology used for creating the Gemini models. “Open models feature free access to the model weights, but terms of use, redistribution, and variant ownership vary according to a model’s specific terms of use, which may not be based on an open-source licence,” stated the company blog.  

Released in two sizes, 2B and 7B, the models outperforms Meta’s open source model Llama 2 on several benchmarks including MMLU, HellaSwag and HumanEval. However, Llama 2 is completely open-sourced unlike Gemma.
