“Claude… doesn’t know who you are?” by Smaug123

Follow-up to https://www.lesswrong.com/posts/Jkb4CBB7rf4XYP5eb/claude-knows-who-you-are after the release of Claude Opus 4.8. Claude Opus 4.8 refuses to do the stylometric identification task at a much higher rate than Claude Opus 4.7 did. More interestingly, when it does take a guess, it is consistently unable to identify me from my writing, from prompts as close as I could get to those 4.7 was able to use. I'm an incredibly minor Internet presence. It's true that 4.7 wasn't completely consistent at identifying me, and indeed its ability seemed to vary over time (! People who weren't me had very different success rates to each other reproducing the experiment to identify me), but 4.8 has a literally 0% success rate so far in my testing. Extremely interested to hear insights or other replication attempts. --- First published: May 28th, 2026 Source: https://www.lesswrong.com/posts/T5aWBLDdkqPEzDhjZ/claude-doesn-t-know-who-you-are --- Narrated by TYPE III AUDIO.
