# Gemma: Google Open Source Model Family

**Gemma** is the family of lightweight, open-weight language models created by Google DeepMind, built around the same research and hardware technologies that power Gemini models.

## Gemma Generations: Gemma 1 and Gemma 2

Google has expanded the Gemma catalog into two main generations with various parameter scales to cover everything from local mobile devices to workstations and corporate servers:

### Gemma 1

2B and 7B

Pioneering ultralight models for inference on commercial consumer CPUs and GPUs.

### Gemma 2

2B, 9B and 27B

Advanced architecture that rivals open models twice its size.

### Specialized

CodeGemma

Variants specialized in source code autocompletion and debugging.

## Open Deployment and Development Ecosystem

All Gemma models have publicly available weights on platforms such as [Hugging Face](https://comunicagenia.com/en/blog/hugging-face-learn-more-about-this-community-that-works-for-ai/), Kaggle and GitHub, accompanied by notebooks ready to run in Google Colab with support for frameworks such as PyTorch, JAX and Keras.
