@Natasha_Jay This really is a major issue with #AI.
Even if you use things like #Gemini "Deep Research", it still loves to make things up it couldn't research properly. For instance, I once tried to use it for researching axle ratios of cars and every time I've repeated the same request, it came up with different numbers.
(It can come up with decent results though for topics where lots of scientific papers are available, like life cycle emissions of vehicles with different propulsion types.)
