Multi-Tier LLM Failover Chain

Relying on a single LLM provider in production is a recipe for disaster.

When inevitable API outages, strict rate limits, or sudden credit exhaustion hit, your entire autonomous pipeline crashes, leaving you with broken workflows and requiring manual intervention.

This integration implements a resilient, cascading failover architecture across three distinct LLM providers (e.g., OpenRouter to Gemini Direct to Groq).

Each tier attempts the extraction, logs the exact failure reason, and seamlessly falls over to the next provider. Crucially, if total failure occurs, it returns a structured default rather than crashing your app.

Why You Need It: Stop babysitting provider status pages. Guarantee 24/7 reliability for your LLM-powered pipelines with enterprise-grade resilience against upstream failure.
