THE LABS
Companies, research groups and independent builders publishing decision models, each with its strongest releases. Open a lab to see every model it has published.
@supersonic-labssupersoniclabs.ia.br
Brazilian lab building the Julia family of small decision models, starting with the 144M-parameter Julia 1.
