Architecture
Why sync requests?
Direct linear flows for the absolute fastest time-to-first-token. Eliminate all external state while remaining firmly anchored in our automated failover routing.
Background Execution
AI runs asynchronously in isolated worker pools. Your backend remains lightning fast and completely insulated from thread exhaustion.
Automatic Fallback
Seamless multi-provider failover baked deeply into the pipeline. Achieve five-nines orchestration without altering any of your client architecture.
Instant Delivery
Real-time WebSocket conduits autonomously push the final streaming payloads directly back to the active client layer.
