World-model startups won't tell their own data suppliers what they're building.

TechCrunch reported from an All In panel that AMI Labs and World Labs declined to describe products, timelines or applications. The supply side has the concrete evidence: Physicl CEO Alex de Vigan, who sells training data into these companies, said "I wish they would tell us more. We could build more useful data if we knew what they were working on." AMI co-founder Michael Rabbat's answer was "We'll talk about it when we're ready to talk about it." For anyone evaluating world models as a bet, there is currently no public interface or benchmark to plan against.
