Architectural Philosophy
- LLMs as Cognitive Layers: Language models should reason, explain, and assist—not replace physics or control logic.
- State Over Data: Digital Twins must model behavior and evolution, not just metrics.
- Production First: Observability, tracing, and evaluation are mandatory for real-world AI systems.
- Human-Centric AI: Systems should communicate clearly with operators and engineers.
