This can result in some funny interactions. I don't know if Claude will say anything, but I've had some models act "surprised" when I commented on something in their thinking, or even deny saying anything about it until I insisted that I can see their reasoning output.

Supposedly (https://www.reddit.com/r/ClaudeAI/comments/1seune4/claude_ch...) they can't even see their own reasoning afterwards.

It depends on the version. For the more recent Claudes they've been keeping it.
