A Chemistry Agent Argued With Its Own Calculations
ARCHE generated reaction hypotheses, ran computational workflows and revised its conclusions against the results.
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 The authors tested it on reconstructing stereocontrolling transition states, proposing a radical pathway for an unpublished cleavage reaction, and finding a descriptor for selectivity in nickel-catalyzed coupling.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.
