Not sure about this upcoming development, but they had the math part solved already via a Wolfram Alpha plugin which integrated into ChatGPT. As you may already know, Wolfram can already solve complex math problems with just a natural language input, so this isn’t anything revolutionary.

What would be revolutionary though is if it applied that same sort of logic beyond math, like towards language (and visual) outputs and be able to fact check, or at the very least, not contradict itself or hallucinate like it does sometimes.
