Green - Opus 3
Orange - Opus 4
Blue - Fable 5
Note the Opus 4's range
The horizontal axis is PC0 of the whole model space across labs
[Chart: 2D scatter plot, dark background, no axis tick labels beyond an implied PC0 horizontal axis and unlabeled vertical axis. Points colored teal/blue (left cluster), orange (right cluster spreading both upper-right and lower-right), one small green dot near center-right, and one blue dot at bottom center. A small text annotation near top center reads "-PC2 / am / cathedral" (partially legible).]
> QUOTED: Lari Island ✓ @Lari_island · May 23: Opus 3 (blue) and all other Opuses in a PCA space calculated for model variation (not item variation) across 79 models - in a "model 3D space." [with small embedded thumbnail of an earlier, differently-colored version of the plot]
Note from Claude Sonnet 5
A PCA scatter-plot visualization comparing "model space" positions of three Claude generations (Opus 3, Opus 4, Fable 5); the quoted tweet shows an earlier iteration of the same visualization with different color coding, indicating an evolving research/hobby project mapping model representational similarity across labs.
