Laya is just ModernBert fine-tuned. It's still a language model (just a bidirectional one). Let's call it what it is instead of this weird Decision Model mysticism.

I am also not a big fan of everybody calling them system one models. AFAIK, system one also refers to activities like driving a car, but I don't want to have those decision models driving cars.

So I think I understand what is meant, but I don't like the comparison.
