This includes concepts such as meaning, intent, or even translation. A well-known LLM model is GPT, Generative Pre-Trained Transformer. PDF, or Portable Document Format, is a popular digital document type. LLM and PDF together may refer to the idea of leveraging LLM models to automatically understand PDF documents. Advanced companies like Instabase leverage LLM models to understand documents like PDF and automate processes that are document heavy.
