Single provider

The single strategy routes every request to a single configured provider. No failover, no load balancing, and deterministic routing.

Best for: Dev/test environments or single-provider setups where you want predictable behavior.

The JSON below is a policy definition, the configuration you set when creating the routing policy, not a field on the POST /responses request body

1 {
2   "name": "Simple OpenAI",
3   "default_strategy": {
4     "type": "fallback",
5     "providers": [
6       { "provider": "openai", "model": "gpt-5.2" }
7     ]
8   }
9 }

For production workloads, consider Priority or Intelligent routing for automatic failover and cost optimization
