Strongest in Language (#9 of 57), weakest in Core abilities (#88 of 204). Above par in 9 of 11 scopes. Among the models it meets almost everywhere, it finishes behind Claude Fable 5 and Claude Fable 5.1 and ahead of Qwen3.8 Flash Next and Claude Opus 4.6.
§ 1 · Profile
What it is good at
Bars run from 50 — the average of the models each source lists — so right of the line is above par. The middle column is the gap to whoever leads that scope.

What it beats, and what beats it
The same models turn up scope after scope. Counted once: where both were placed, who finished higher. Bars run right for Union Alpha, left for the other.
