Alessio Fanelli: belief

12 Mar 2026 Latent Space Retrieval After RAG: Hybrid Search, Agents, and Database Design — Simon Hørup Eskildsen of Turbopuffer

“You know, I think sometimes it’s like, well, these are the tradeoffs, but the three nines, it’s like, actually it’s not a real trade off because we can make something that nobody has ever made before and actually make it work.”

Transcript context

…Uh, yeah, yeah. My, my, my world. My world. How, how do you reconcile some of these things when you’re saying you bend the will the computer versus like the tradeoffs? You know, I think sometimes it’s like, well, these are the tradeoffs, but the three nines, it’s like, actually it’s not a real trade off because we can make something that nobody has ever made before and actually make it work. The way I think about the bending trajectory to your will is, um, if you sit down and do the napkin math, right, where you’re just like, okay, like if I have a hundred machines, they have this many terabytes of disc, they have this bandwidth, whatever, right? And you sit down and you just do the like high school napkin math on this is how many qps we should be able to drive to it. Similar to how I did the vibe pricing, right? If you can sit down and do that, and then you observe the real system and you see, oh, we’re off by like 10 x bendings trajectory to your will is like just making the software get closer and closer to that first principle line. The P 99 might even be able to cross the line Right. By finding even more optimizations than, than, than from first principle. So bending the software to your rail is about that, right? Like a hundred millisecond P 99 to um, to S3. I mean now you’re talking like someone really high agency that like goes to Seattle finds CS three team and it’s like, how are we gonna make this 10? You know, like it’s that, that’s not quite what we talk about. Right. But yeah.…
