AI Tutoring Systems Achieving Functional Parity
#1AI tutoring systems have crossed a threshold where, for knowledge-transfer tasks in well-defined subject domains, they are producing learning outcomes statistically indistinguishable from — and in some studies superior to — human TA-facilitated tutoring. Khanmigo is deployed to millions of users with documented engagement and learning gains. The Wharton GPT-4 tutoring study (Bastani et al., 2023) showed 2-sigma performance improvements in math, replicating Bloom's famous human-tutoring effect. Synthesis has grown from SpaceX-employee use to a commercial platform with measurable problem-solving gains. These are not pilots — they are production deployments at scale.
