I've been kinda disappointed with the $10 plan tier of the AI assistant. It looks good at first glance - shows you that it's doing a bunch of research, you can see which sources it's looking at etc. But then when it goes to report results on anything data heavy it makes a lot of mistakes with putting figures under the wrong headers, using incorrect values etc.

The last time I used it heavily was a few months ago so it might have gotten better, and I assume the more expensive tier where you can choose which models it uses might be a bit better depending on which model you choose. I much prefer just pointing my own local agent harness at a search api at this point though.
