How often do AI models refresh what they know about my business?

It depends on whether the tool is reading live or remembering. Perplexity, Google AI Overviews, and the browsing modes of ChatGPT and Copilot fetch current pages, so a change on your site or Google Business Profile can appear within days once it is recrawled. The model's baked-in training knowledge is a different story and can lag by many months.

That gap is why a business that rebranded, moved, or changed its phone number keeps getting described the old way. Update the live sources first, then keep publishing so crawlers have a reason to come back, and expect the stale training memory to fade only when the model itself is retrained.
