The theoretical capacity of a binary network is 69% of the capacity of a full-weight network, so it makes sense that LLM would converge to 1-bit networks in the long term.

It's nice to finally see practical networks reach the theoretical limits found in the statistical mechanics of Ising models. A good pointer to efficient 1-bit training, from the statistical mechanics point of view, is here:
