## AI overview

OpenAI and Molecule.one describe a near-autonomous AI chemist using GPT-5.4 and the Maria laboratory system to improve Chan-Lam coupling. The system generated proposals, designed and ran experiments, analyzed data, and achieved higher measured yields for most tested substrates, with humans providing oversight and validation.
