OPTIMIZATION & ORCHESTRATION
01
⚡
Dynamic Model Routing
Route each prompt to the right model based on task complexity, cost thresholds, and latency requirements. Automatic fallback when quality permits.
Routing
02
🔬
Token Waste Detection
Score prompts for efficiency. Detect redundant context injection, bloated system prompts, and high retry rates. Actionable recommendations to cut spend.
Cost Intelligence
03
🛑
Budget Circuit Breakers
Per-team, per-feature, or global spend limits. When limits are hit, StackSense auto-downgrades model tiers or rate-limits requests — no service disruption.
Budget Enforcement
04
⚖️
Cross-Vendor Arbitrage
Monitor real-time pricing and latency across all providers. Automatically shift traffic to maximize value without degrading user experience.
Multi-Provider
05
📋
Governance & Audit Logs
Tamper-evident audit trail of every AI call. Model allowlists, PII detection, data residency enforcement, compliance reporting for SOC 2.
Governance
06
🤖
Agent Tracking
Track multi-step agentic workflows end-to-end. Total cost per agent run, infinite loop detection, task-level token budgets.
