I ask "what is TiDB" in the demo as suggested, and it takes 2 minutes to start responding in the midst of a multi-stage workflow with several steps each of graph retrieval, vector search, generation, and response combination.

Each of these is individually cool, but it strikes me as tragic that so much effort has been put into an intricate workflow and beautifully crafted UI only to culminate in a completely useless hello-world example, which after 5+ minutes of successive querying and response-building concludes with a network error.

I could use this to build exactly what I need...after stripping out 80% of the features to make it streamlined and responsive.

Why isn't that minimal version the default?

It appears to be much faster on more specific questions (like the ones that are suggested after you ask it "what is TiDB"). I got a response in about 40s on the question "How does TiDB's cloud-native design enhance its scalability and reliability compared to traditional MySQL databases?"

Also, what's wrong with a nice UI? It appears to mostly be components from https://ui.shadcn.com/. Is there something wrong with good frontend craft, especially for a demo where you're trying to sell something?

It seems like something that is being offered as a self-contained tool that's easy for end users to play with, which isn't going to be the minimal version. I'm sure you could build something that suits your needs exactly, but it would be hard for someone else to predict your exact needs, and there's a decent chance everyone needs or wants a slightly different set of features, and that those things may not make for the most ideal demo.

I am personally far from the typical profile of an AI booster, but I can't help but say something about what I feel is a middlebrow dismissal.

What would you remove?
