Aarush Selvan: evaluation

18 Feb 2025 Latent Space The Inventors of Deep Research

“Like, there are things that you might not optimally spend time verifying, even though the models like, like, this is a very common fact the model already knows and it's able to like reason over and balancing that out between trying to leverage the model memory versus being able to ground this in, is in, you know, some kind of a source is the challenging part. And I think as, as like you rightly called out with the thinking models, this is even more pronounced because the models know more, they're able to like draw second order insights more just by reasoning over.”

Transcript context

…I feel like there's a little bit of a conflation of inference time compute here in a sense of like, one, you can infer算 compute with the model, the thinking model. And then two, you can infersin compute by searching and reasoning. I wonder if there that gets in the way, like when you presumably, you've tested thinking, plus deep research, if the thinking actually does a little bit of verification. And then there's a little bit of thinking, plus deep research. Maybe it saves you some time or it like tries to draw too much from its internal knowledge and then therefore searches less, you know, like does it step on each other? Yeah, no, I think that's a, that's a really nice call out. And this also goes back to the kind of use case. The reason I bring that up is there are certain things that I can tell you from model memory last year, the Fed did X number of updates and so on. But unless I sourced it, it's going to be hallucinated. Yeah, like one is the hallucination or even if I got it right, as a user, I'd be very wary of that number unless I'm able to like source the .gov website for it and so on. Right. So that's another challenge. Like, there are things that you might not optimally spend time verifying, even though the models like, like, this is a very common fact the model already knows and it's able to like reason over and balancing that out between trying to leverage the model memory versus being able to ground this in, is in, you know, some kind of a source is the challenging part. And I think as, as like you rightly called out with the thinking models, this is even more pronounced because the models know more, they're able to like draw second order insights more just by reasoning over. Technically, they don't know more, they just use their internal knowledge more. Right?…
