short_description: Comparing LLM tokenizers in multiple languages
---

# All languages are NOT created (tokenized) equal! 🌐

Gradio app that compares the tokenization length for different languages across various LLM tokenizers.

For some tokenizers, tokenizing a message in one language may result in 10-20x more tokens than a comparable message in another language (e.g., try English vs. Burmese).
