Workflow economics
Track cost per run and identify expensive chain branches.

LangChain integration
LangChain cost tracking integration
LangChain gives structure for chains and agents. Opsmeter adds spend ownership so each workflow path has clear cost accountability.
Chain traces alone cannot answer which workflow path is driving budget pressure.
Why default tooling falls short
Chain traces alone cannot answer which workflow path is driving budget pressure.
Release guardrails
Spot cost drift tied to prompt or model changes in one workflow.
Operational ownership
Assign costly workflows to product and platform owners with evidence.
Setup checklist
Attach workflow identity
Carry workflowTag and run identifiers into model calls.
Include endpoint and tenant keys
Bridge chain events to customer and endpoint ownership context.
Stream usage to Opsmeter ingest
Post request-level usage for each workflow execution step.
Example event mapping
| Field | Example value | Why it matters |
|---|---|---|
| workflowTag | invoice.triage | Enables cost/run and cost/workflow concentration views. |
| stageTag | rerank | Identifies expensive workflow stage transitions. |
| tenantId | midmarket-eu | Connects workflow cost with account-level margin. |
| promptVersion | triage_v5 | Exposes release-linked workflow regressions. |
How Opsmeter operationalizes this path
Emit run-scoped metadata
Add workflowTag and run identifiers to each model request in the chain.
Normalize usage fields
Send token and cost metrics in a consistent payload across models.
Inspect workflow concentration
Use by-workflow and by-endpoint views to isolate the expensive stage.
Ship attribution without gateway rewrites
No proxy rewrite required. Keep your current app path and enrich request metadata.
