This is one of the imo underdiscussed consequences of everyone using the same handful of models. No matter how good LLMs become at coding or how far they advance on the exponential METR chart, AI writing will still read like slop because we quickly learn to recognize the style.

this is why the "AI will be better than humans at writing" predictions won't come true while we're all using the same model.

writing is an anti-inductive domain: ankitmaloo.com/anti-inductive/

this means that as we all collectively experience a new model and its "better" style, its starts to wear on us and no longer becomes a marker of quality, just as it would if all AI wrote exactly like V.S. Naipaul

even as AI wins writing competitions judged by literati unfamiliar with AI who don't examine the work closely, most people on here who read AI writing a lot will still consider it slop

ultimately this seems partly due to the fact that on-policy RL seeks the mode of the distribution, neglecting to capture the tails. if you think I'm wrong, then my challenge is: come back when you've solved in-weight continual learning

If we want safe models, it makes sense to care about alignment during the entire training cycle, and not only at the post-training stage (as it is typically done now). Check out this work investigating how to do it properly!

New paper!
Synthetic Persona Pretraining (SPP): Alignment from Token Zero

Rather than aligning models after pretraining, we do so from the very start.

SPP models are more faithful to our constitution, less misaligned, & more robust to jailbreaks. Advantage grows with scale! 馃У

We are entering the world of (even greater) power concentration in the hands of a few large companies, and it's not a bright world.

Well, labs have finally started closing the doors on AI capabilities. Imo, it has never been more important for open-source and open-weight models to catch up. A (few) winner-takes-all situation is not something I look forward to.

1/ Did you ever look at some feature represented by a Transformer and wonder: "Why would it even learn that? 馃 "
We did! Announcing the ICLR'26 paper "Understanding the Emergence of Seemingly Useless Features in Next-Token Predictors"
