Going by the screenshots in the linked tweets, it seems like it performs searches on Bing in order to obtain up-to-date information to answer its questions with, so there's probably not a need to re-train it daily. So the main question here might be "how much energy does it cost to keep a search engine up-to-date", which may not be cheap, either.

There is probably a need to refresh it periodically to account for what the MMAcevedo fictional story [1] calls "context drift" -- the relevant search terms to infer from the query are themselves contextual. Say, if I ask Bing today "is Trump running for president", the right search term today could be "donald trump 2024 election", but ten years from now it might be "eric trump 2036 election".
