HTML vs Markdown for LLMs: Why Clean Structure Beats Raw Pages
A recent article highlights that feeding raw HTML directly into Large Language Models (LLMs) can lead to noisy context windows and inefficient token usage. The author argues that LLMs understand clean Markdown significantly better than HTML, which often contains extraneous elements like navigation menus, ads, and styling wrappers. Converting HTML to Markdown before ingestion can drastically reduce token count, improve semantic chunking, and enhance the overall accuracy and consistency of RAG systems and AI agents. AI
