I’m pretty sure some of the newer ChatGPT-like products (the consumer-facing interface, not the raw LLM) do in fact do this. They try to detect certain types of inputs (i.e. math problems or requesting the current weather) and convert it to an API request to some other service and return the result instead of a LLM output. Frankly it comes across to me as an attempt to make the “AI” seem smarter than it really is by covering up its weaknesses.
If this keeps up we might get a Part 3 to this meme.
