Secure Account Rotation for AI Agents

ROUTER_NOTEBOOK
When multiple agents consume the same AI layer, the classic mistake is treating all accounts equally. In practice, not all accounts, not all models, nor all times of the day behave the same.
The lesson from this project is that rotation must be contextual:
- By model,
- By quota state,
- By operational risk,
- And by the actual capacity of the fleet.
What we learned
The first version of a rotator is usually too simple: round-robin load balancing, hoping the provider forgives. That approach works for a while, until one account gets banned and drags the rest down with it.
The important shift was moving to a more conservative decision model:
- Measure first,
- Rotate only when necessary,
- Isolate accounts showing signs of enforcement,
- And store enough telemetry to understand why each decision was made.
Why it matters
This kind of tool doesn’t just save money. It also improves resilience, reduces surprises, and turns AI usage into an operable system, not just a series of improvised executions.
