Efficient multi-provider agent environments with AI gateways: best practices

Organizations are increasingly adopting multiple AI models to optimize performance and cost for agent tasks and LLM calls, without a clear frontrunner emerging. Treating inference like a pipeline, teams routinely evaluate and switch models for different stages, using lightweight models for simpler tasks and frontier models for complex synthesis. However, infrastructure challenges complicate rapid iteration, safety, and compliance enforcement, especially when providers throttle requests or experience performance issues. AI gateways address these challenges by offering a unified API endpoint for accessing multiple models, enhancing security and reliability while simplifying model evaluation and selection. Gateways enable centralized fallback, retries, and rate limiting, improving agent reliability and budget management. They allow for easy model configuration changes without modifying application code, facilitating iterative model selection. Observability is crucial for understanding trends and ensuring gateway reliability, while budget controls are essential for managing costs and preventing overruns. The integration of observability tools like Datadog provides trace-level visibility into LLM calls, aiding in monitoring and optimizing agent environments.
