Industry proposes behavior-centric AI design paradigm

KEY FACTS

  • Current agent-centric design lets large models decide program control flow, making systems fragile and hard to scale.
  • The article argues for switching to behavior-centric design, translating intent into reusable behaviors and invoking frontier models only when needed.
  • The agent-centric approach originated from ChatGPT's launch in November 2022 and the opening of the function calling API in June 2023.
  • Gartner predicts that more than 40% of agentic AI projects will be canceled by 2027.
  • A McKinsey report states that only 37% of enterprises using AI can demonstrate financial impact.

PHYSIX OBSERVATION

Agent-centric design hands control flow to probabilistic models, and fragility and cost problems surface as soon as scale increases. The behavior-centric approach treats reusable behaviors as first-class citizens and calls large models only when necessary, which is closer to the engineering intuition of enterprise-grade software. For users, this means future AI applications may be more stable and cheaper, rather than piling on more agents to cross-check each other.
