Enterprises use GenAI for email and calendars, not core systems — small self-hosted models may fill the gap

Linthicum argues most enterprises aren't using generative AI for core applications like inventory control — mostly calendar management and email drafting, often via unapproved shadow AI.

He contends waiting for bigger frontier models won't change this: core systems need narrow, self-hosted models built on in-house data, since small models are easier to test and debug. He says he's never been able to trace a bad answer inside a frontier LLM, which rules them out for business systems.
