Update: After reading Kei’s comment, I noticed that Sonnet 4.5′s system card also mentioned that the summarization only happens in a small minority of cases. This makes me less confident that I’m right, since it increases the likelihood that the absence of discussion in the Opus 4.5 and 4.6 system cards is a deliberate omission. On the other hand, Anthropic was very transparent about their approach to summarization up through Sonnet 4.5, so I’d also be slightly surprised about them silently changing this.

Do you think the slobbering thoughts were lengthy enough to trigger the summarizer?
Probably not, but the summarizer could additionally be triggered by unsafe CoTs.
