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.
the family reading
What ties the family together
A rare fully-labeled post-training lineage: Ai2's OLMo-2 1B publishes its base and all three sequential post-training stages (SFT -> DPO -> RLVR/Instruct), so the atlas can walk the chain stage by stage. Off the plain-continuer base, every stage reads as the same clear, turn-taking assistant disposition. On the disposition axis the SFT and DPO stages read the SAME (indistinguishable-at-ceiling) — the atlas does not manufacture a method difference. IMPORTANT: the stages are SEQUENTIAL (base -> SFT -> DPO -> RLVR), so base -> DPO carries the SFT stage plus an increment; this is NOT a clean parallel SFT-method-vs-DPO-method contrast, which is shown honestly as an abstain, not a separation.
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.
