Model Routing & Failover

Hyperion routes requests universally using configurable pipeline policies designed around your business constraints: cost, latency, quality, or custom ML classifiers.

Strategic Routing Modes

  • Priority Routing: Explicitly prefer one provider or model for an endpoint, with immediate fallback configured if the primary becomes unhealthy.
  • Cost-Aware Routing: Dynamically pick a cheaper model if the gateway's ML classifier determines the prompt satisfies an "easy" threshold (e.g., standard summarization vs mathematical reasoning).
  • Latency-Aware Routing: Route traffic strictly to the provider responding with the lowest TTFT (Time To First Token) historically over the last 5 minutes.
  • Quality Routing: Route traffic based on human-in-the-loop or automated unit test benchmarking for specific prompt variations over time.
  • Hybrid Weighted Routing: Combine all above modes into weighted A/B/C testing or gradual rollout policies.

Example Configuration (YAML)

routing:
  default:
    - case: latency < 100ms and cost < 0.005
      model: provider-a/gpt-fast
    - case: user_tier == enterprise
      model: provider-b/gpt-quality
    - else:
      model: openai/gpt-4o
  failover:
    max_retries: 2
    backoff: exponential

Smart Classification & Resilience

Hyperion's lightweight ML classifier detects "cheapable" requests instantly. You can route simple CRUD-like AI extraction tasks dynamically without littering your core application codebase with complex logic loops.

On top of this, Hyperion guarantees resilience with automatic active-passive failover. Every provider gets measured health checks (monitoring latency averages and error rates in real-time). You can rotate load across multiple keys to bypass arbitrary provider rate-limits, and configure strict circuit breakers to pause entirely anomalous API traffic originating internally.
