Adaptive Model Routing and Fallback Logic: Routing Around LLM Provider Outages with Bifrost
Bifrost is an open-source AI gateway designed to maintain application uptime during LLM provider outages. It employs adaptive model routing and fallback logic to dynamically select the best provider and handle failed requests without requiring code changes. This infrastructure approach addresses the increasing frequency of provider outages and ensures reliable performance across multiple LLM providers.
- ▪Bifrost uses adaptive model routing to choose the best LLM provider based on real-time performance metrics.
- ▪The fallback logic in Bifrost automatically retries failed requests against backup providers.
- ▪By 2026, adaptive routing and fallback logic became essential for maintaining application reliability during frequent LLM outages.
