At this point we might as well adopt that joke where you blindly throw away half the resumes because you don't want to hire unlucky people.

A person's total luck is constant over a lifetime. The remaining half of the candidates already spent some of their luck in this selection, so they'll be on average less lucky than the discarded half.

Donald Trump disproves the fixed luck hypothesis (and the Karma hypothesis!)

And this lies at the heart of the problem. We expect computers to be consistent despite running programs that are not designed to be consistent. This despite the fact that we have lots of experience of programs running on computers that produces wildly inconsistent outputs. But for some reason some people choose to assume LLMs should act like a calculator instead of any of those programs.

> This despite the fact that we have lots of experience of programs running on computers that produces wildly inconsistent outputs. The average user has very little. A word processor with inconsistent pagination or a spreadsheet with inconsistent totals is rightly seen as faulty.

Yeah but daily tools have lots of complexity which appears as non determinism (if we are thinking only UX, not actual determinism). For example, try moving an image in the word doc. I have been using MS word my entire life it seems, still don't know what the rules are lol.

An alarming number of people don't understand that LLMs work via purely stochastic processes, so I'm happy to see in-depth pieces like this. I'm looking for a job and maybe this is why it's so hard to get a callback these days: resumes are just dumped in some LLM black hole and no one really knows how it works.

The same person is not going to give you three different answers within span of minutes. Especially when nothing fundamentally has changed. People might or might not update their views depending on their biases.

Of course life isn't fair. But here the result is that companies will ignore potentially great candidates which dedicate all their programming time to their job and instead consider candidates which may be not just worse programmers, but also are more interested in their hobbies (or padding their CV) that doing their job. I'm saying this as somebody who most of the time has some side project going on.

The takeaway from this for me is that, using an LLM to score anything takes multiple (maybe even many) runs and the result you’ll get is, at best, a sane-ish distribution. Which sort of sounds workable until you scale it up to larger datasets, where at some point compute/time/energy costs will render it non-viable. I am sure there’s some reasonable rule of thumb estimation on distribution that could be applied based…

My experience with benchmarks and evals is that it can take ~20 runs of a problem for the distribution of answers to start to converge. Ideally you'd know the convergence properties of your algorithm ahead of time and make a Bayesian solution that makes the uncertainty explicit.

>in theory theory, temperature 0 doesn't really exist. It does exist very much, even if you go to pure math. Look at the softmax function and take the limit as T->0. It becomes a dirac-delta function. I.e. in a discrete setting (like for LLMs with a finite set of output tokens), probability P becomes one for argmax and 0 for everything else. Only in coding practice it is easer to implement T=0 as a simple if check th…

> Look at the softmax function and take the limit as T->0. It becomes a dirac-delta function. In pure math, it does not always do that. It becomes a dirac-delta comb with equal weight on every maximum. There can be more than 1 maximum. Setting the temperature to zero turns into greedy sampling, but greedy sampling is not necessarily deterministic as you can have multiple equally optimal options.

That is not a problem for LLMs, because in practice floating point inaccuracies (in particular after exponentiation) prevent values from being exactly equal. That's why greedy sampling generally produces deterministic output for LLMs. The real gotchas are elsewhere (like with batch inference as we've seen with earlier GPTs). But unlike what the earlier comment says, this is a non-issue mathematically.

It took me a a minute to figure out what an ATS was. Not familiar with this particular means of a much used TLA.

Even better Wikipedia lists the abbreviation I am familiar with but give a different interpretation of the same words:

a studied example is sampling judicial decisions before lunch and after lunch. judges are more lenient on a full stomach.

how did they account for sampling bias? a judge might leave easier cases for after lunch. people with control over their schedules usually ease themselves back into it after breaks.

Wdym, cant you just litter your applications with buzzwords and other bs to automatically get a high score in these systems?

I have been at both side of the market. And it sucks so bad at both ends. Companies which deeply care about next hire are struggling to hire and actual great people looking out are outcompeted by AI slop and AI bulk applying. It is actually a very hard to solve problem.

The mind blower is that this spam and slop is just lowering the job market to the quality of every other capitalist market. Poor hiring manager has to look through 1000 applicants, 950 of which are spam? How many ads are shoved down your throat every day, and how many products are you actually looking for info on?

Chickens coming home to roost.

To be clear, temperature 0 is deterministic and will produce the same output for exact duplicate inputs, across all seed choices.

Provided:

* If it’s MoE we are talking about, that the duplicate inputs are for the whole batch (yes, your batch neighbours can impact your choice of experts. Blergh.)

* Your kernels are deterministic

* There’s no system wide effort switch that responds to, e.g. work load across the cluster (for a thinking model)

Upshot:

Temperature 0 is not deterministic in probably any existing cloud infra, but it could be for edge inference pretty reliably.

To your quibble on 0.1 being more deterministic - I think it’s a pretty fair summary - we’re going to sample much more from the ‘temp 0’ answer at 0.1 than we would at temp 0.9, no?
