I've currently only set this up on two dev sites but the setup was easy and the bot seems to perform well (using GPT-4.1 Nano). I'm no AI expert so can't give you comparison between the models, but it seems to answer questions well with the data I've fed it.

There have been some features that were missing or not quite working, but whenever I've raised this via their own live chat, they've listened and fixed or added features very quickly (shout out to Hasen from support!).

While I've not deployed a bot into a production environment yet, I will soon and currently, I've no concerns about doing so!

If the dev team keeps working on this, adding features and fixing any issues, I think it's going to be a great tool for the future.
