Yeah, exactly. And that's, I think, up from 1% a couple of months ago. And that was August, which sounds really far away. So God knows what it is in October. And so there's that stat. I think that was really interesting. But then there was another stat that I really liked from a blog post that they had in June this year about recursive self-improvement, which explained the concept. But then they presented this kind of dual-arm experiment where they were testing out different model generations versus a human in this setup where first a human would undertake a research agenda and go a couple of steps down this path, deciding what to work on, doing the work.
And then at some point, that experiment would fork, and the human would continue, or a specific model generation would continue. And it would be the old Sonnet versions to Opus to then Claude 4. And then the experiment would end, and human graders would look at the human path versus the model path. And it was something like the older generation of models, humans preferred 10% of the time or something like that. But for the frontier-class models, humans preferred that research direction 64% of the time.
Which suggests that models are getting better at predicting the right steps or the right interesting kind of leaves in the nodes to pursue. And then the second piece of data I liked was some research from OpenAI with their Codex usage amongst their AI staff, where they tried to classify the token use in the overall process of their research. And that would be using tokens for deciding what research question to test, how to test it, what experiment you should set up, writing the training code, running the data engineering pipelines, writing the infrastructure, et cetera, and then marketing the paper, writing the paper, et cetera.
And the vast majority of the token usage was on explaining and research writing, which kind of makes sense, sort of knowledge work, followed by all the infrastructure for running the experiment. Very, very few tokens were used for what question should I explore and why should I explore it and what's the right path. And so I like this question a lot because I was trained in science and biology and I just remember, this is like 10 years ago or 15 years ago, not that long, but at the start of the PhD, you would sit there with a ton of papers and you'd go on the internet and read, read, read, read, read, try to understand what's the status quo, how do people test certain ideas, where are the gaps, what experiment should I run?
Yeah. And then in concert with your supervisor, decide on the path. And the best supervisors would be the ones who could guide you down the most fruitful path to get hopefully your Nature paper, and then off you were. And the worst supervisors were the ones that didn't really know or didn't have great ideas. So that idea of research taste, which is what kind of gets bandied around on Twitter a lot, is, I think, one of the hallmarks of intelligence and is one of the critical components towards RSI working well.
And is one that I just really enjoy because it speaks to my interest in science.
Yeah, indeed. Taste has sort of become a clichéd word over the last couple of years. But in the specific context of RSI, just to play back what you just said, it's effectively choosing the right problem. Yeah, that's the right word.
Yeah, exactly. And a lot of famous inventors will say it's like invention is a result of good taste, and a lot of the work is choosing what direction to work on, not necessarily just boiling the ocean. And so if we want to be using tokens correctly, using our compute budgets correctly, but also showing that our systems are smart, they shouldn't just be boiling the ocean.
And conquering taste is something that you see happening in your various conversations as something happening in the next few months,
maybe longer. At least a year. I think the problem is, how do you objectively measure taste? I mean, in art, I guess you can because it's perfectly observable. And maybe in wine you can sort of express why this taste is better than that taste. But in science and engineering, where there's different paths to getting to the right result, it's not immediately clear. Would it be the model that consumes the fewest tokens to get to an answer that humans believe is the best?
Is it like the journey that matters more? And I think maybe the whole uproar in the maths community of AlphaEvolve solving, or whatever model it was, solving various open questions.
