Anthropic plausibly uses Brave Search... and Brave search maintains its own index. Makes sense: cheaper search API, leveraging non-Google, etc.

Here we are, one layer of indirection more: Ceramic, Exa, Linkup. Who knows what they use. If you told me that those 3 build and maintain their own index, I'd first question whether that was true, and if it is, I would question whether it was any good (relative to Google/Bing/Brave).

So what is CF providing here? Maybe some free credits to entice us to use their router? No, not that either ("billed to your AI Gateway credits"). Maybe a comparison of which agent search yields the best results? Nope.

It's a crappy proxy- probably less efficient and more volatile than hitting the agent API directly.

This is only if I understand the product correctly (which I admittedly skimmed) due to the sheer number of screeching vibey nothingburgers coming out of CF over the past month.
