Stanford studied 51 real AI deployments and found a 71% vs 40% productivity gap - here's what separates the two groups

I came across a Stanford research paper that actually went inside companies running AI in production - not pilots, not surveys, real deployments. They found something that stuck with me. Companies using what they call "agentic AI" - where the AI owns the task start to finish with no human approval loop - are seeing 71% median productivity gains. Companies using standard AI that assists humans are averaging 40%. Same technology. Nearly double the output. The kicker: only 20% of companies are in the 71% group.
