I'm in on the #bing #gpt #binggpt Beta. Super impressive and game changing not just for search, but for comparative research. The Bing integration is great, and the sidebar in Edge super useful.
The model looks to be up to date, but there's a gap. For example, I asked how are the political representatives for my area and the aggregate results were old (last year), but specific questions were correct (for the new session).
But this is game changing. Not just about search, but information aggregation. SEO rules don't apply here. Which sites get ingested into the model with relative weightings is going to be crucial. I just hope sponsorship does not skew the model. If it does it's going to be impossible to separate sponsored search results vs. regular results.
