A11 and AGI: A Structural Approach for Models

1. What AGI Actually Requires (A Structural Definition) In open discussions, “AGI” is often described as: a very large model, a universal problem solver, a human‑level agent, a system based on subjective experience. These definitions contradict each other and do not provide an engineering criterion. A structural definition of AGI: AGI = a system with a stable vertical cognitive architecture capable of generating, evaluating, and refining its own direction (S1), constraints (S2), knowledge (S3),
