Re: Study identifies weaknesses in how AI systems are evaluated

I've been getting flagged by high-on-their-own-supply AI boosters for identifying that LLM benchmarks have been obvious bullshit for at least the last year and a half. What changed to make "the inevitable AI bubble" the dominant narrative in last week or so?

Link those comments please because I checked your history and the flagged ones were pure nonsense with zero insights. Also, calling out LLM benchmarks has never been a radical take and basically the default on this site.

LLMs can probably be taught or configured to use external tools like Excel or Mathematica when such calculations are needed. Just like humans. There are plenty of untapped optimization opportunities.

I don’t think the fact that LLMs can handle small numbers more reliably has anything to do with their reasoning ability. To the contrary, reasoning ability should enable them to handle numbers of arbitrary size, just as it enables humans to do so, given some pencil and paper. However: > Testing only on these problems would not predict performance on larger numbers, where LLMs struggle. Since performance on large numb…

Pencil and paper is just testing with tools enabled.

You seem to be addressing an argument that wasn’t made.

Personally, I’d say that such tool use is more akin to a human using a calculator.

I’d say it’s fair for LLMs to be able to use any tool in benchmarks, so long as they are the ones to decide to use them.

For statistical AI models, we can use out of sample prediction error as an objective measure to compare models. What makes evaluating LLMs difficult is that comparisons are inextricable from utility (whereas statistical AI models do have a pre-utility step wherein it can be shown out of sample prediction epsilon is minimized).

I'm not addressing an argument, just stating that's already a form of LLM testing done today for people wanting to look at the difference in results the same as the human analogy.

I work on LLM benchmarks and human evals for a living in a research lab (as opposed to product). I can say: it’s pretty much the Wild West and a total disaster. No one really has a good solution, and researchers are also in a huge rush and don’t want to end up making their whole job benchmarking. Even if you could, and even if you have the right background you can do benchmarks full time and they still would be a mes…

For what it's worth, I work on platforms infra at a hyperscaler and benchmarks are a complete fucking joke in my field too lol. Ultimately we are measuring extremely measurable things that have an objective ground truth. And yet: - we completely fail at statistics (the MAJORITY of analysis is literally just "here's the delta in the mean of these two samples". If I ever do see people gesturing at actual proper analysi…

Even a p-value is insufficient. Maybe can use some of this stuff https://web.stanford.edu/~swager/causal_inf_book.pdf

Or given a calculator. Which it's running on. Which it in some sense is. There's something deeply ironic about the fact that we have an "AI" running on the most technologically advanced calculator in the history of mankind and...it can't do basic math.

Okay, but then I don’t understand why you replied to my comment for that, there is no direct connection to what I wrote, nor to what bee_rider wrote.
