LLM High Availability: Strategies for Multi-Provider Fallbacks and Failover

By PulseAugur Editorial · [1 sources] ·

This article discusses strategies for building highly available LLM applications by implementing multi-provider fallbacks and failover mechanisms. It distinguishes between retries, which resend a request to the same target for transient errors, and fallbacks, which switch to a different provider when a target is persistently unavailable or problematic. A reference configuration is provided, demonstrating a priority-based routing system that first attempts to use Azure's GPT-4o, then OpenAI's GPT-4o, and finally Anthropic's Claude Sonnet, with specific retry logic for each.

IMPACT Provides architectural patterns for developers to ensure consistent access to LLM services, mitigating downtime and rate limits.

    Multi-Provider Fallbacks and Failover: Designing for LLM High Availability

    <p>ny application that depends on a single large language model provider inherits that provider's bad days. Providers have outages, impose rate limits during traffic spikes, return transient server errors, and occasionally slow to a crawl under load. If your architecture has exac…
