TL;DR: Inference costs are falling, but the routing problem, not model price, determines where deep analysis earns its cost, according to Cycode. The practical lesson is that AppSec teams need deterministic controls as the always-on layer and selective AI analysis for high-blast-radius changes.
Editorial analysis by NHI Mgmt Group, based on content published by Cycode: “The Token Dilemma: Why AI Security Scales on Architecture, Not Model Pricing”.
Key questions
Q: How should security teams decide where to use deep AI analysis in code review?
A: Use deep AI analysis only where the marginal value exceeds its cost.
Q: Why does cheaper model pricing not solve enterprise AI security coverage?
A: Because the binding constraint is scale, not unit price.
Q: What do teams get wrong about AI code review and security gates?
A: Many teams assume human review can reliably catch dangerous AI output if they add it to existing workflows.
Practitioner guidance
- Implement deterministic-first coverage Run SAST, SCA, secrets, IaC, and policy checks on every commit so routine findings never depend on expensive reasoning.
- Define selective AI trigger rules Use blast radius, deployment topology, ownership, and dependency shifts to decide when a deeper AI scan is justified.
- Retire developer self-triage for security prioritisation Avoid asking developers to rate their own code risk, because the routing decision needs independent signals rather than self-reporting.
Bottom line: The article frames AI security economics as a control problem, because broad deep-analysis coverage does not scale cleanly across enterprise code volume.

AI security now has a routing problem, not just a model problem: the deciding factor is where expensive reasoning is applied, not whether a model can detect more issues. In large engineering estates, universal deep analysis creates cost and latency pressure that quickly turns into governance friction. Practitioners should treat model selection as secondary to control allocation.
A few things that frame the scale:
- Only 23% of IT leaders were very confident in their organisation's ability to manage security and governance for GenAI deployments, according to a 2025 Gartner survey of 360 IT leaders.
A question worth separating out:
Q: What is the difference between deterministic scanning and selective AI scanning?
A: Deterministic scanning finds known patterns cheaply and continuously, while selective AI scanning uses deeper reasoning on a smaller set of high-value changes. The first is the base coverage layer; the second is the escalation layer. Treating them as substitutes creates waste, while using them together creates economically sustainable coverage.
