Transformer Visualizer

Abstract: This paper focuses on unraveling the inner work- ings of the transformer architecture, a cornerstone of modern enabling parallel processing and long-range dependency cap- ture. From this seminal work, w√e adopt the core attention large language models (LLMs). While transformers have driven mechanism formula (Q × K^T )/  d_k and the multi-head at- breakthroughs in natural language processing through self- attention mechanisms, their internal operations remain complex and opaque. Using GPT-2 as an illustrative case study, we develop an interactive visualization framework to map information flow, display attention patterns, and illustrate token embeddings and layer interactions. These visualizations aim to deepen compre- hension of transformer mechanics, enhance model transparency, and guide future advancements in AI design.
