PDF Understanding

• Agents can now understand PDFs that are uploaded in a conversation
• PDF Understanding is powered by two features:
  • Traditional OCR to extract readable text from the PDF and provide it to the Agent
  • PDF-to-image conversion that enables the Agent to “see” the first 5 pages of the PDF

1. Only the first 5 pages of the PDF are processed into images that the Agent can “see”; only the readable text from remaining pages is provided to the Agent
2. PDFs bigger than 3MB may fail to process
3. PDF-to-image conversion causes a delay in the Agent’s response time
4. PDF URLs that are accessed via the Scrape URL tool do not have PDF-to-image conversion enabled, so the agent will only get extracted text
