❓ Frequently Asked Questions
Why is standard OCR bad for RAG pipelines? ▼
Traditional string-based OCR loses table column relationships and splits paragraphs awkwardly across line breaks, causing vector embeddings to hallucinate. Modern VLMs like Mistral OCR 4 and olmOCR-2 preserve HTML tables and LaTeX math intact.
What is LlamaParse Cost Optimizer? ▼
LlamaParse's Cost Optimizer dynamically routes simple text pages to its $1.25/1k Fast tier while reserving the $12.50-$56.25/1k Agentic tiers solely for complex charts, reducing total ingestion costs by up to 80%.
