Anything territorial with a social structure (wolves, horses & boars being great examples of successful domestications, otters and falcons for in-progress domestications and foxes and raccoons good candidates) are prime domestication material as the human can become the social leader and they won’t be as inclined to leave what is their pack’s territory
That said, it takes thousands of years to fully domesticate something, which is why “semi-domesticated” otters and falcons just sort of help out with hunting without being “friendly” enough to be predictable
The difference between reasoning models and normal models is reasoning models are two steps, to oversimplify it a little they prompt “how would you go about responding to this” then prompt “write the response”
It’s still predicting the most likely thing to come next, but the difference is that it gives the chance for the model to write the most likely instructions to follow for the task, then the most likely result of following the instructions - both of which are much more conformant to patterns than a single jump from prompt to response.
