What is Google Gemma?

What is Google Gemma?

Google Gemma refers to a family of lightweight, state-of-the-art open models created by Google DeepMind and other teams within Google. These models are derived from the same research and technology used to develop the Gemini models and are named after “gemma,” which means precious stone in Latin.

Gemma models are optimized for various devices, including laptops, desktops, Internet of Things (IoT), mobiles, and cloud computing, and are compatible with cross-platform tools such as Keras, PyTorch, JAX, and Hugging Face Transformers. They are particularly notable for achieving top-notch performance relative to their size when compared to other open models.

The models come in two sizes—Gemma 2B and Gemma 7B—with both pre-trained and instruction-tuned variants provided. Gemma models include a Responsible Generative AI Toolkit, which offers guidance and essential tools for creating safer AI applications. They are available globally and can be deployed easily on Google Cloud services such as Vertex AI and Google Kubernetes Engine (GKE)

Gemma's release expands Google's AI product ecosystem, providing researchers with a powerful tool for experimentation. Despite not reaching the sheer power of models like GPT-4 or Gemini, Gemma focuses on delivering a lightweight, efficient, and high-performance model for on-device applications.

As the open-source ecosystem matures, we can anticipate the emergence of more powerful LLMs, bridging the gap between open and closed-source models.

A Closer Look at Gemma's Architecture

Awni Hannun, a machine learning research scientist at Apple, conducted an insightful analysis of Gemma. Noteworthy is Gemma's extensive vocabulary of 250,000 tokens, enabling it to handle tasks with complex language more effectively than comparable models with 32k tokens. This versatility extends to various content types, including math, code, and other modalities.

An intriguing feature is the massive embedding weights (750 million), crucial for mapping words to representations of meanings and relationships. These weights are not only used in processing input but also play a role in generating the model's output. This sharing enhances the model's efficiency, leading to more accurate, relevant, and contextually appropriate responses.

Google Gemma AI and the Issues of Safety

Google Gemma AI and the Issues of Safety

The decision to release Gemma as an open model raises concerns about potential misuse. While researchers can leverage Gemma for legitimate purposes, there's a risk of generating misinformation or harmful content.

Melissa Ruzzi, AppOmni’s Director of Artificial Intelligence, was one of those that expressed concerns about the risks associated with open-source AI. While acknowledging the potential of powerful models like Gemma, developed based on Gemini, Ruzzi emphasized the empowerment of malicious actors. Speaking to Techopedia she said:

“It’s nearly impossible to implement enough controls to keep this from happening and still have a functional model. This is the biggest problem to solve with open-source AI models.”

But Google aware of this ensured that Gemma was designed, from the ground up, to prioritize responsible usage.  Gemma underwent rigorous processes to ensure safety and reliability. Training data underwent careful filtering to eliminate personal and sensitive information, and reinforcement learning from human feedback (RLHF) played a crucial role in training the model for responsible behavior.

Google's Responsible Generative AI Toolkit, released alongside Gemma, further assists developers and researchers in building safe and responsible AI applications. This toolkit includes safety classification methodologies, a model debugging tool, and guidance based on Google's experience in developing large language models.
