I hope that they are going to put something in Claude Code to display if you're entering the expensive window. Sometime I just keep the conversation going. I wouldn't want that to burn my Max credits 2x faster.

Yeah, that 1 MM tokens is a $15 (IIRC) API call. That's gonna add up quick! My favorite hypothetical AI failure scenario is that LLM agents eventually achieve human level general intelligence, but have to burn so many tokens to do it that they actually become more expensive than a human.
