I have a similar question and I’m inferring the answer is no - look at the cache hit rate of 23% for the 128GB M5 Max. I had previously assumed that the 40B active meant that a set of layers was chosen as THE expert for a given prompt and generation was then limited to those layers until complete. But in that case you’d have expected the expert caching to have a super high hit rate once you had enough RAM to hold an entire expert’s worth of layers.
