Visualizing Byte-Pair encoding Tokenization process in LLM | HuggingFace | Python
In this video, we dive deep into Byte-Pair Encoding (BPE) - the popular tokenization algorithm powering some of the most famous Large Language Models today. Instead of just looking at the theory, we are going to actually visualize the tokenization process step-by-step using a custom Python library I built called “hf-tokenizer-visualizer”.
By the end of this tutorial, you'll understand how character pairs are merged into new token IDs based on their frequency and how to generate beautiful node-graph visualizations of this exact merging process.
What is hf-tokenizer-visualizer?
It's a Python library that visually maps out how the BPE tokenizer encodes your text. It generates a directed graph where nodes represent individual characters or tokens, and the edges show exactly how and when they merge.
