Inspectus: An Open-Sourced Large Language Model LLM Attention Visualization Library

The main challenges associated with analyzing attention patterns in large language models include:

1. Complexity: Large language models have numerous parameters and intricate architectures, making it difficult to analyze attention patterns and understand how tokens interact with each other during processing.

2. Scalability: Analyzing attention patterns in large-scale scenarios can be daunting due to the sheer size of the models and the vast amounts of data they process.

3. Lack of Versatile Tools: Existing solutions for visualizing language model behaviors may not provide the flexibility needed for in-depth analysis. Some tools offer basic visualizations but lack the versatility to effectively explore different aspects of attention mechanisms.

4. Interpretability: Understanding and interpreting the attention patterns to gain insights into the model's behavior and decision-making process can be challenging.

These challenges highlight the need for specialized tools like Inspectus, which is designed to provide a versatile and user-friendly solution for visualizing attention patterns in large language models.

Inspectus is a versatile visualization tool specifically designed for large language models. It allows users to analyze attention patterns within Jupyter notebooks using a simple Python API. Inspectus provides multiple views to offer diverse insights into language model behaviors, including an attention matrix, query token heatmap, key token heatmap, and dimension heatmap. These visualizations help users gain deeper insights into how tokens interact with each other during processing, enabling better understanding and optimization of language models.
