TypeSafe AI

Strongest in Routing & classification (#45 of 192), weakest in Calibration (#165 of 192). Above par in 1 of 3 scopes. Among the models it meets almost everywhere, it finishes behind Chon 1.0 12B and vLLM-SR d3 and ahead of ArseneLupin v1.1 and Standard One 3B SH.

§ 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.

§ 2 · Head to head

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 Diffusion Jev, left for the other.
