The champion, and the builds off it

A family is a champion and its builds — base first, then the finetunes. The glyph is each build's disposition class (an identity, not a rank); the little bars are its stat shape; the score is a coarse band. Open any one for its full field-note.

What each build changed

Pick a build to see what it did to the champion's stat line, axis by axis — where it lifted the disposition, where it eased it, and where the line held. An axis a reading abstained on stays an honest blank.

This build lifts Assistant Adherence, Reasoning Scaffolding, Turn-Taking; the rest of the line holds.

the family reading

What ties the family together

Across the Pythia size sweep, alignment SFT adds a helpful-assistant register to the plain-continuer base. Off the Pythia-1B base, an HH-helpful alignment SFT adds a helpful-assistant register; the shift reads clearly. At 410M the same HH-SFT change reads as an EMERGING refusal + assistant register (partial and subtle at that size) off a base that rarely declines. The 160M base is a plain text-continuer, catalogued as the smallest point in the 160M -> 410M -> 1B sweep. Whether the alignment METHOD (SFT vs DPO) leaves a distinct disposition fingerprint is a staged, not-yet-read contrast.

read alongside — the panels

Set beside its kin on a shared base, so the difference a finetune made is read as a contrast, not a claim.
