…The Planck constant is a set distance. It’s being used here to define other things as a constant. The very article on the kilogram states outright that SI units’ foundation is three constants: “a specific transition frequency of the caesium-133 atom, the speed of light, and the Planck constant.”
Vacuum permeability is how much electric currents affect magnetic fields in a vacuum. As in, when there are no other interferences. It is not variable. The speed of light when there is no interference is not ‘affected by’ vacuum permability any more than a cartesian graph is ‘affected by’ the set of real numbers. Vacuum permeability describes vacuum, it doesn’t define it. Same goes for permittivity.
You ARE correct about the kilogram no longer being a number of specific atoms, though.










The only thing that changes is the data that is passed to the LLM, which for each iteration includes the last token that the LLM itself generated. So yes, sort of. The LLM itself doesn’t change state; just the data that is fed into it.
It’s also non-deterministic insofar as similar inputs will not necessarily give similar outputs. The only way to actually predict its output is to use the exact same input - and then you only get identical token probability lists on the other end. Every LLM chatbot, by default, will then make a random selection based on those probabilities. It can be set to always pick the most probable token, but this can cause problems.
