StackLens assessment

Questions to answer before choosing

  • Which records need the higher-cost model?
  • Can validation failures trigger selective escalation?
  • Do modality or thinking-token rules affect the real workload?
Workload caveat

What this estimate leaves out

Document parsing, OCR, validation infrastructure, and failed-record handling are outside this token estimate.

Latency, reliability, output quality, retries, regional processing, and provider-specific tool charges can change the practical decision.
