Indeed they are evolving very fast. It's useful to be aware of why hallucinations happen though. Generally the risk is higher for hallucinations when some combination of a lack of relevant input or highly constrained output means there are few non-hallucinated possibilities for generation. In this case it's the former: there is no place for it to go and find the flights you're looking for, since publicly-freely-accessible realtime flight search APIs do not exist. Which is why computer use is the key to enabling this kind of use case.
