    I wonder what the "waves" in LLMs are; The global firing patterns that can help us interpret what the weights are doing en-masse

      Why would you assume waves with LLMs? What about the structure or function of an artificial neuron prompts you to hypothesize they generate continuous waves in a bunch of nested frequency ranges?

        OP was postulating that there might be higher order patterns we can see arise out of underlying LLM mechanics.

          Brain waves are due to feedback paths and dynamics - oscillations etc, but LLM connectivity is far simpler. In an LLM there is a strict bottom-up one-way flow of information, with no looping. There is no way for a higher up layer to affect a lower down layer, whether directly or indirectly.
