Atom 1 — Physics-IQ Verified i2v submission (4 runs)

Moving Atoms · Physics-IQ Verified · Image-to-Video

4-run aggregate: 47.06 ± 1.32 (4 independent runs, seeds 42/1042/2042/3042). Individual run means: 45.44 / 47.27 / 46.88 / 48.64. System frozen across runs (LoRA weights, planner labels, prompts byte-identical); only the diffusion seed varies. Current i2v board leader: MiniMax H3 at 39.8 ± 0.3 (2026-08-24) — Atom 1's own base checkpoint.

Atom 1 is MiniMaxAI/MiniMax-H3 (FL2VA bf16 open checkpoint) post-trained with a Moving Atoms physics LoRA (WISA-80K, rank-16 attn) + the Atom Harness: a planner that once assigned each scenario a motion class (settling/continuous/cascade/quiescent) from the switch frame and official description alone; the templater then deterministically writes the class's timed clause into the prompt. One sample per case, no selection.
