Why We Built a Self-Healing AI Gateway: Architecting for Provider Instability

Source: Dev.to

The Fragility of the “Wrapper” Era

Why openai.chat.completions is a single point of failure.

Native Infrastructure vs. Shims

Why we abandoned SDK shims for native Go implementations of Google and Groq protocols.

The Health-Check Loop

How Nexus uses a background goroutine to monitor provider latency and error rates.

Autonomous Re‑routing

The logic behind switching from a primary model to a secondary “Speed” model (Groq) when latency spikes.

Conclusion

Why “Sovereign Infrastructure” is the only way to scale AI to the enterprise.
