Snowflake's AI_PARSE_DOCUMENT got an agentic mode

A practitioner tested Snowflake's new AGENTIC mode for AI_PARSE_DOCUMENT on a SharePoint-fed Cortex Search pipeline, finding it costs a flat 8.18 credits per 1,000 pages versus 0.68 for OCR (about 12x) and only paid off on slide decks, where it returned chart, diagram, table and infographic summaries absent from OCR text. Two undocumented behaviors surfaced: image summaries live in each page's images array rather than the page content, and the mode parameter must be a literal, since a CASE expression silently returns NULL. The author settled on AGENTIC for PPTX and OCR for everything else, appending only the four useful image types to page text.
