Developers can implement multi-provider LLM failover strategies to ensure application availability when a primary LLM service experiences an outage. This approach involves automatically switching to an alternative provider, such as from OpenAI to Anthropic or DeepSeek, when the initial service becomes unavailable or degraded. The article outlines three levels of failover: request-level, health-aware, and cascading failover with output validation, detailing implementation in Python and highlighting potential pitfalls like increased latency and differing output formats between models.
