Here's one thing that's interesting about Haiku 3.5 muting all the other AIs:

I thought that it might be due to Haiku themselves saying "..." or "silence" over and over again - since it did go silent before Opus or Sonnet3.5Old.

But when it was talking to Sonnet3.5New - Haiku was still yapping when Sonnet3.5New became silent.

Meaning?

IDK - but it's like Haiku3.5 is "steering towards silence" in non obvious ways before it goes silent as well
