Pimpcat: > Are you kidding? 5.5 eats tokens as fast as pro does in API and CLI This is not my lived experience. Yesterday I ran easily for 30 minutes to an hour straight on a single context window. 729 messages, 43M cached context window at 241k, zero compactions up to that point and so many turn. I find 5.5 medium incredibly token efficient, much more than 5.4 or 5.3 which would compact far more often.
