Model routing for agentic workflows: are your controls keeping up?

TL;DR: Using Jev for model-routing decisions can cut token costs and wait time for agentic workflows, with a benchmark projecting about 98.3% lower routing token costs and materially faster decision latency than larger LLMs, according to Tetrate analysis. The governance implication is that routing logic is becoming its own control plane, so teams must separate decision cost from task quality and keep host-enforced permissions intact.

Editorial analysis by NHI Mgmt Group, based on content published by Tetrate: “Jev-directed Model Routing”.

By the numbers:

• At 1,000 routing decisions, the benchmark projected roughly 3 cents for Jev versus $1.61 for GPT-6 Sol.
• Across 1,000 developers making that many decisions each month, the annual volume reaches 12 million decisions, about $322 for Jev versus $19,281 for Sol.
• Jev made the decision 12.3 times faster than Luna and 19.8 times faster than Sol, comparing medians.

Key questions

Q: How should security teams govern model routing in AI agent workflows?

A: Security teams should treat model routing as a policy decision, not a performance shortcut.

Q: Why can cheaper routing still leave overall agent risk unchanged?

A: Because routing cost is only one part of the workflow.

Q: What are the signs that model routing is becoming a governance problem?

A: The clearest signs are repeated route changes without clear criteria, rising decision latency across many small tasks, and teams unable to explain why a specific route was chosen.

Practitioner guidance

• Define routing policy as governed logic Document which tasks may be routed by a decision model, which criteria are allowed, and which routes require host enforcement before tool use.
• Measure routing separately from task completion Track token spend, decision latency, and downstream task outcomes as separate metrics so you can see whether routing changes total workload economics.
• Keep permissions outside the router Maintain explicit permission checks in the host or execution layer so a routing model cannot become the authority boundary for tool access.

Bottom line: Model routing is now a control point in agentic workflows because it decides which model or action receives the next task.
