TokenOps Maturity Matrix
Where does your stack stand? Four pillars, three levels — from initial to corporate / automated.
| Pillar | Level 1: Initial | Level 2: Optimized | Level 3: Corporate / Automated |
|---|---|---|---|
| Monitoreo | Alertas globales de presupuesto mensuales | Registro de tokens por agente y función | Análisis de anomalías en tiempo real con apagado automático |
| Contexto | Carga masiva de archivos | Prompt Caching nativo estricto | Compresión de prompts + lazy-loading dinámico |
| Modelos | Un único modelo de frontera | Reglas estáticas de ruteo (Styrr) | Ruteo dinámico por costos/latencia |
| Finanzas | Gasto global en factura consolidada | Costo desglosado por tokens (Showback) | Costo por tarea terminada y ROI de negocio |
AWS Deterministic Stack
The AWS services that make deterministic guardrails real — the grounding ledger, loop control, and prompt savings.
Ontology graph — the Grounding Ledger (SPARQL/Gremlin T-Box)
Deterministic loop control — the agent never decides when to iterate
Up to 90% input-token discount on cached prefixes
aws-samples — OWL ontologies in Neptune for grounding & delivery
aws-samples — OntoForge: deterministic entity/relation extraction
