Google AI Research Introduces GQA: Training Generalized Multi-Query Transformer Models from Multi-Head Checkpoints

The text discusses the introduction of multi-query attention (MQA) in large language models to expedite decoder inference, addressing the trade-offs in efficiency and quality. It emphasizes the benefits of uptraining language model checkpoints using MQA and proposes grouped-query attention (GQA) as an alternative approach. The objective is to enhance the efficiency of language models while minimizing memory usage, with acknowledgment of testing limitations and potential effectiveness for information generation models.

Enhancing Language Models with Multi-Query Attention

Accelerating Inference and Enhancing Language Models

In the world of language models and attention mechanisms, we have discovered a technique called multi-query attention (MQA) that promises faster results for decoder inference. This approach expedites decoder inference and enhances the efficiency of large language models by using a single key-value head.

Challenges and Solutions

While MQA offers speed, it may lead to a decline in quality and training instability. To address these challenges, we have introduced two practical solutions:

  1. Uptraining language model checkpoints to incorporate MQA with a minimal fraction of the original training compute, offering rapid multi-query functionality and high-quality results.
  2. Implementing grouped-query attention (GQA) as an interpolation between multi-head and multi-query attention, achieving quality levels close to multi-head attention while maintaining a speed comparable to that of multi-query attention.

Practical Applications

Employing language models for swift responses becomes expensive due to high memory demand. Our proposed approach transforms multi-head attention models into multi-query models using only a fraction of the original training, reducing memory usage without compromising model size and accuracy.

Conclusion

The objective of our research is to enhance the efficiency of language models in handling substantial amounts of information while minimizing computer memory usage. This is particularly crucial when dealing with longer sequences. Our approach aims to address these challenges and offer practical solutions for improving language model efficiency.
