TL;DR:
- Define one canonical gateway schema before building dashboards, because team-level cost attribution fails when request metadata drifts.
- Capture model, tenant, user identity, input/output tokens, and request cost at the edge for OpenAI, Anthropic, and Bedrock.
- Compare approaches using proxy-native controls, telemetry reconciliation, and hybrid stacks before choosing one.
- Use 30-day reconciliation loops and anomaly checks to keep allocation logic trustworthy, not just pretty.
- Use the AI Cost Attribution Auditor to cross-check spend by team and accelerate chargeback conversations with evidence.

Vishal, your point about attribution breaking when request metadata drifts is the piece Iād make explicit in the rollout. I would treat the gateway event as the source of truth and require every downstream model call to carry the same stable fields: request_id, tenant_id, team_id, feature, environment, model, input/output tokens, unit price version, and retry_of when applicable. Then reconciliation is less about perfect dashboard math and more about proving every invoice line can map back to an immutable request event. That also makes chargeback disputes easier because the evidence is at the boundary, not reconstructed later. How are you handling retries or router failover in your schema?
