How this term is used : After this chapter you will be able to identify which problems fall outside the limits of LLMs — verifiable correctness, spatial reasoning, exact determinism — and select the newer architectures and form factors built to solve them: energy-based models, hybrid diffusion–autoregressive video models, and asynchronously orchestrated coding agents. — in which the term points at written inputs that drive those agents, we situate the entry within its assigned topic: Beyond LLMs: New AI Architectures and Capabilities. What you'll take away from this conversation: why LLMs are architecturally awkward for mission-critical work, what energy-based models (EBMs) are and how they differ, and how one company is betting that verifiable, inspectable AI fills a gap LLMs can't.
