Perhaps I’m missing this, but can Qwen 3.8 alter Qwen 3.8 weights?

There are a lot of known neurons in the older Qwen models that are long known to induce behaviour changes (see evil Qwen by changing one weight).

My question boils down to how much is trained vs being able to actually understand the weights. Presumably a same gen model isn’t trained on any sources dissecting that generation. And how much do longer known conceits like steering vectors, J spaces, LoRAs play into this?

This doesn’t explain the game training cases, which are very impressive to me.
