Was this with GPT-4?

I used it to plan a summer European trip to 17 cities and didn't notice any hallucinations for what must have been 20 hours of back and forth creating itineraries, day trips, etc.

Did not use it as my only source of info, still watched some videos by Rick Steeves and Wolter's World, but it far and away was the most efficient part of the planning process for me.

Yes gpt 4. I was fact checking and using places I knew pretty well and would find the occasional error when asking it to describe cities etc and what to do.

Well for itineraries, given that its training data gets cut off at some point, I’d also be worried about it recommending places that are no longer open.

Note that I’m building an app for customers and attempting to build a brand that can be trusted - whereas in your case gpt 4 is probably ideal given you know it’s caveats and can check the important stuff.

I've also used it a few times to suggest things to do in the last few months. It came up with OK suggestions.

Also, they literally just demoed something similar as this project as part of their recent keynote on new openai stuff. The demo featured focused on their new assistant api.

I've actually grilled chat gpt a bit on geographic information on a few occasions. It's not perfect but surprisingly good. It obviously extracts a lot of that from things like wikipedia.

You can actually ask it to answer in geojson format, paste it in geojson.io and end up with a usable map. It seems to know about a lot of landmarks; including coordinates. For smaller venues, the coordinates are not super accurate.

You can also ask it to provide geojson for the boundingbox of a city or area. I even asked it to pretend to be an in car navigation system and provide me with directions to an address. It half succeeded in listing correct streets but messing up right and left. With the latest chatgpt it just asks bing.

The topic of this thread is intended to be a loose recreation what was used in the OpenAI demo. I guess my assertion is that it could work quite well for a travel agent type of functionality, at least for the type of service an average travel agent provides. For something like a tour guide that needs to gives depth it probably does fall flat quite a bit.

I can totally understand not being great for smaller landmarks... it could be the case too that it could trigger a call to an external service for things it doesn't have high confidence about.
