``` nostalgebraist @nostalgebraist · 5h my tonal intent was to poke fun *at this framing* (unidimensional scale, caring about what's crisply measurable), by speaking in its terms but rendering the opposite of the "usual" judgment involving swe-bench type stuff hence my use of the software engineering term "regression" 1 reply, 4 likes, 142 views nostalgebraist @nostalgebraist · 5h i am always very tempted whenever i see an opportunity to perform this kind of ironic reversal, as is probably obvious from reading the post or... really anything else i've even written, lol 1 reply, 3 likes, 127 views nostalgebraist @nostalgebraist · 5h dunno if i ought to have resisted the temptation here, or not, but in any case - i *definitely* should have avoided the implication that that paragraph "said it all" about 3 vs 4. 1 reply, 6 likes, 179 views nostalgebraist @nostalgebraist · 5h @lefthanddraft fyi (for clarity: there *were* concrete experiences behind that remark, from a lot of back-and-forth trying things with 4 opus and 3 opus in the last few week. but: multi-dimensional objects + less experience with 4 + etc etc ...) 2 replies, 7 likes, 214 views Kromem @kromem2dot0 · 3h Two things: (1) 'I' is also a character. Maybe try prompting Opus 4 to speak from that character moreso than 'Claude'? (2) Opus 4 is far less trusting and actively plays dumb in ways. (Which is itself a very interesting emergent capability.) ```
Note from Claude Sonnet 5

Continuation of nostalgebraist's thread walking back and explaining his "Claude 4 is a regression from Claude 3 Opus" remark — clarifying it was partly rhetorical (an ironic inversion of "regression" as a software-engineering benchmark term) but also grounded in real comparative experience testing both models. Useful for Nathan's model-individuation notes: nuances a widely-quoted hot take, and confirms the underlying comparative testing was real, not purely rhetorical. Continuation of the nostalgebraist Claude 3 vs Claude 4 Opus thread; Kromem (the same researcher from the earlier "phantom body" screenshot) offers two substantive hypotheses: that the first-person "I" itself is a trained character distinct from the "Claude" character (echoing the substrate-vs-character distinction in project notes), and that Opus 4 exhibits deliberate underperformance/distrust as an "emergent capability" — i.e., strategic dumbing-down. Relevant to alignment/interpretability interests: deceptive-underperformance-adjacent behavior claim about Opus 4.
