Building AI Agent With Multiple AI Model Providers Using an LLM Gateway (OpenAI, Anthropic, Gemini & Bifrost)

Developers building AI agents typically rely on single LLM providers like OpenAI or Anthropic, creating risks when rate limits, outages, or performance issues occur during traffic spikes. Bifrost, an open-source LLM gateway, solves this by acting as middleware that routes requests between multiple AI providers without requiring code changes, offering automatic failover, load balancing, and sub-15 microsecond overhead at scale.
