Deterministic First. Models When Needed.
AI does not make every software problem an AI problem. I learned that applied AI engineering depends on choosing where probabilistic intelligence adds value—and where deterministic software is safer, faster, cheaper, and easier to govern. Enterprises need an architecture that supports model escalation for genuine ambiguity without forcing every task through an LLM.
What I learned
- Specific learning
- A source that initially appeared to require model assistance could be interpreted through a reusable deterministic pattern. The right response was to improve the deterministic capability while preserving a bounded escalation path.
- Implementation evidence
- The accepted real-source evaluation moved 21 source locations through normalization into 21 private Mapspring locations: 21/21 materialized, with zero missing, unexpected, or duplicate locations, zero model calls, and zero geocoding calls.
- Enterprise implication
- Treat model use as an architectural decision, not a default. Define escalation conditions, measure cost and uncertainty, and prefer repeatable software where it is sufficient.
