Nexus Labs conducted a 30-day production test comparing three AI gateways: Bifrost, LiteLLM, and Portkey, to evaluate their failover capabilities and latency overhead. Bifrost demonstrated a 11ms p99 latency increase with its automatic provider fallback, successfully rerouting traffic during an OpenAI outage. While LiteLLM offered valuable custom cost-tracking callbacks and Portkey showed promise, Bifrost's synchronous fallback evaluation was noted as a key advantage for reliable production traffic management.
