I think it's equally copium that people keep assuming we're just going to compound our way into intelligence that generalizes enough to stop us from handholding the AI, as much as I'd genuinely enjoy that future.

Lately I spend all day post-training models for my product, and I want to say 99% of the research specific to LLMs doesn't reproduce and/or matter once you actually dig in.

We're getting exponentially more papers on the topics and they're getting worse on average.

Every day there's a new paper claiming an X% gain by post-training some ancient 8B parameter model and comparing it to a bunch of other ancient models after they've overfitted on the public dataset of a given benchmark and given the model a best of 5.

And benchmarks won't ever show it, but even ChatGPT 3.5-Turbo has better general world knowledge than a lot models people consider "frontier" models today because post-training makes it easy to cover up those gaps with very impressive one-prompt outputs and strong benchmark scores.

It feels like things are getting stuck in a local maxima: we are making forward progress, the models are useful and getting more useful, but the future people are envisioning takes reaching a completely different goal post that I'm not at all convinced we're making exponential progress towards.

There maybe exponential number of techniques claiming to be ground breaking, but what has actually unlocked new capabilities that can't just as easily be attributed to how much more focused post-training has become on coding and math?

Test time compute feels like the only one and we're already seeing the cracks form in terms of its effect on hallucinations, and there's a clear ceiling for the performance the current iteration unlocks as all these models are converging on pretty similar performance after just a few model releases.
