This reflects pretty much every result of mine from Google these days. Not just navigation, but search too.
The only thing I can figure is that Google's consumer-facing free-to-use models are set to "reason as fast as possible with only the most basic plausibility checks." I have to correct them like this every single time.
Uh, yes, of course. search results are fast & cheap & free, why would they use the good models?
Genuinely curious: why do you use them then? It's not like there is no competition in this area.
