But an LLM model could perform poorly in tests that it is not considered and essentially means "death" for it. But begs the question at which scope should we consider an LLM to be similar to identity of a single human. Are you the same you as you were few minutes back or 10 years back? Is LLM the same LLM it is after it has been trained for further 10 hours, what if the weights are copy pasted endlessly, what if we as humans were to be cloned instantly? What if you were teleported from location A to B instantly, being put together from other atoms from elsewhere?

Ultimately this matters from evolutionary evolvement and survival of the fittest idea, but it makes the question of "identity" very complex. But death will matter because this signals what traits are more likely to keep going into new generations, for both humans and LLMs.

Death, essentially for an LLM would be when people stop using it in favour of some other LLM performing better.
