    If Jev is fundamentally trained using RLCD while you’re building on a Qwen model that was trained using RLHF, how can the resulting model be considered Jev-like?

      I can't find it but saw that if you give Jev English alphabet as choices and ask it in a loop what model it is, it would say Qwen

      also tried myself: <a href="https:&#x2F;&#x2F;console.typesafe.ai&#x2F;playground?share=shr_1690a3160f19c2e4851b6a2883bcf17a790" rel="nofollow">https:&#x2F;&#x2F;console.typesafe.ai&#x2F;playground?share=shr_1690a3160f1...

        Can someone explain to me how such self-awareness can be forced into the model. I mean I guess the pre training data could contain all sorts of stuff. How reliable are those hacks. I know that a lot of open weight models answer that they are Claude in the absence of a system prompt. I find destillation not that much of a plausible explanation as typically claude would probably not mention that it is Claude all the time. I find it rather plausible that a foreig. system prompt made it into pre-training. But again: I have no clue how much care is given by models to leave traces for destillation (for closed weights) or post training (for open weights).
