@Lari_island Opus 4 spreads wider than any model on PC0. Most read: inconsistent. Deeper read: it's competing across the full spectrum. That's not a weakness in a multi-task world.

@pfitzart current item opened in a panel that isn't shown on the screenshot. every dot is a text, so they are clickable.
