Gemma 2 (9B)

Google Gemma 2 (9B) is a state-of-the-art open language model developed by Google, designed to provide high-performance natural language processing capabilities in a relatively compact size. As part of the Gemma family of models, it represents a significant advancement in the field of lightweight yet powerful language models.

Model Overview Card Gemma 2 (9B)

  • Model Name: Google Gemma 2 (9B)
  • Developer: Google
  • Release Date: 2024
  • Version: 2
  • Model Type: Text (Language Model)

Description

Gemma 2 (9B) is a 9 billion parameter language model that offers competitive performance compared to larger models while maintaining a practical size. It is designed to be an open model, allowing for widespread use and adaptation by the developer community.

Key Features
  • Interleaved local-global attentions
  • Group-query attention
  • Trained using knowledge distillation
  • Competitive performance against models 2-3 times larger
  • Open-source availability

Technical Details

Architecture

The Gemma 2 (9B) model incorporates several technical modifications to enhance its performance:

  1. Interleaved local-global attentions: This technique, based on the work of Beltagy et al. (2020a), allows the model to efficiently process both local and global context information.
  2. Group-query attention: Implemented based on the research by Ainslie et al. (2023), this mechanism likely improves the model's ability to handle complex queries and relationships within the text.
  3. Knowledge distillation: Unlike its predecessor, which used next token prediction, Gemma 2 (9B) is trained using knowledge distillation techniques. This approach, pioneered by Hinton et al. (2015), allows the model to learn from a larger, more complex model while maintaining a smaller size.
Performance Metrics

The model is described as delivering "the best performance for their size" and offering "competitive alternatives to models that are 2-3 × bigger".
