🔍 Conclusion: Structural Signals
Structural signals
- AI security assessment moves from experimentation to production: No longer a proof-of-concept, but a production necessity in 2026
- Three-tier architecture becomes standard: Three-tier evaluation during prediction, post-generation, and runtime is standard configuration
- Trade-off analysis becomes necessary: Trade-offs between security, latency, and cost are key decisions
- Measurable metrics become standard: latency, error rate, cost, ROI are all required metrics
- Segmentation of deployment scenarios: The deployment configurations of finance, medical, and general customer service are significantly different.
Key Lessons
- Don’t just build monitoring, not execution: Observability tells you what happened, and enforcement tells you what to do.
- Trade-off analysis cannot be omitted: The trade-offs between security, delay, and cost are key decisions
- Measurable indicators cannot be omitted: latency, error rate, cost, and ROI are all required indicators
- Segmentation of deployment scenarios: The deployment configurations of different scenarios are significantly different.
- Cost visibility cannot be omitted: 100% call link traceability is a basic requirement
