Summary

ARCHE generated reaction hypotheses, ran computational workflows and revised its conclusions against the results.

ARCHE combines a general reasoning model, a chemistry-specialized model and a structured tool registry in a closed loop. The authors tested it on reconstructing stereocontrolling transition states, proposing a radical pathway for an unpublished cleavage reaction, and finding a descriptor for selectivity in nickel-catalyzed coupling. In each case the system generated and ranked mechanisms, orchestrated calculations, and revised the explanation from computed evidence. The code is public, but the three demonstrations remain a bounded preprint evaluation rather than proof of autonomous chemistry in the lab.
