Optimize + Defend

Reivo doesn't just watch your costs. It actively reduces them.

Core

Smart Model Routing

Automatically routes each request to the optimal model based on task complexity. High-precision requests stay on the full model. Lightweight tasks go to cost-efficient alternatives. Real-time analysis, zero latency added.

Core

Quality Verification

Routed responses are scored via logprob confidence analysis. If quality falls below threshold, Reivo automatically retries with the original model.Currently available for OpenAI non-streaming requests.

Cost Visibility

Real-time cost tracking across OpenAI, Anthropic, and Google. Per-session, per-agent, and per-model breakdowns.

Budget Guardrails & Loop Detection

Set spending limits with alerts at 50%, 80%, 100%. Detects agents stuck in repetitive loops and auto-stops runaways before they burn your budget.

How Smart Routing Works

Reivo analyzes every request in real-time and selects the optimal model based on task complexity. Complex tasks stay on the full model. Simple ones get routed to a cheaper alternative.

Request Analysis

Evaluates task complexity and required precision in real-time. Zero latency added.

Auto Routing

Keeps the full model for high-precision tasks. Routes lightweight tasks to cost-optimal models automatically.

Full Audit Log

See exactly which model handled each request and why. Every routing decision is logged in your dashboard.

Switch between conservative, aggressive, or off modes anytime in Settings. You're always in control.
