LLMs like GPT-4o can read and interpret documents but produce non-deterministic outputs — the same document may yield slightly different JSON structures across runs, which is incompatible with production financial workflows that require consistent field coverage every time. Veryfi's deterministic models return the same structured output format for every document, making it reliable for automated AP pipelines, compliance reporting, and financial systems where schema consistency is required. LLMs are powerful tools for document understanding and Q&A, but for high-volume, high-accuracy financial document extraction with SOC 2 compliance and production SLAs, Veryfi is purpose-built infrastructure rather than a general AI model.
