QED Predictions of fine structure constant and g-factor

Hi, I know QED is one of the most tested theories in all of science (and one of the most accurate) but I wanted to know if it disagreed at ALL with its predicted values of both

http://en.wikipedia.org/wiki/Fine_structure_constant
http://en.wikipedia.org/wiki/G-factor_(physics )

The thing I keep reading is that it is the "most accurate", but does that mean exactly accurate to within the uncertainties of the experiment (and uncertainties of prediction), or does it differ by a very tiny amount even given the uncertainties. That's it, thanks!

PS: I can only find what the current most accurate measurements are of those two constants, but not what our current theory of QED predicts them to be, else I'd just compare myself.

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
