**Source:** [`atloria-monorepo/libs/agent-core/src/runtime/model-router.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/agent-core/src/runtime/model-router.ts#L80)

Production routing table for atlas-docs-resource (East US 2).

Cost profile vs using gpt-5.6-terra for everything:
  - 60-70% of calls (explore/analyze/tool_dispatch) → nano/mini → ~15-6x cheaper
  - plan/implement (quality-critical) → gpt-5.6-terra full
