Why We Chose Go Over Python to Build an AI Gateway: A Performance Deep-Dive

When building Bifrost, we faced a critical architectural decision: Go or Python? Python dominates the AI infrastructure space—LiteLLM, LangChain, and most LLM tooling are Python-based. But production AI gateways have different requirements than development frameworks. This article explains why we chose Go for Bifrost and the performance advantages that decision delivered. maximhq / bifrost Fastest enterprise AI gateway (50x faster than LiteLLM) with adaptive load balancer, cluster mode, guardrails, 1000+ models support & <100 µs overhead at 5k RPS. Bifrost AI Gateway The fastest way to build AI applications that never go down Bifrost is a high-performance AI gateway that unifies access to 15+ providers (OpenAI, Anthropic, AWS Bedrock, Google Vertex, and more) through a single OpenAI-compatible API. Deploy in seconds with zero configuration and get automatic failover, load balancing, semantic caching, and enterprise-grade features. Quick Start Go from zero to production-ready AI gateway
