Markdown vs. LaTeX: Ingesting Mathematical and Academic Texts for RAG
Why LaTeX remains the standard for raw mathematical equations, but why Markdown wrappers are essential for contextual search and vector chunking.
1. Mathematical Equation Formatting inside LLMs
Academic papers and financial ledgers rely on LaTeX formatting for equations (like `$E=mc^2$`). While LLMs are extremely capable of reading LaTeX syntax, parsing a whole document as pure LaTeX adds massive layout definitions that bloat the token count.
The optimal architecture is a **hybrid Markdown-LaTeX approach**: parse the core document sections and tables using clean GFM Markdown, and wrap inline and block equations inside math fences (e.g. `$$` or `$`). This isolates mathematical definitions while keeping the textual semantic index readable.
