A technical guide details how to configure Claude Code to work with AI gateways, addressing issues that arise when using standard OpenAI-compatible endpoints. The article explains that Claude Code requires a native Anthropic Messages API endpoint, not just a proxy for OpenAI's chat completions, to properly handle tool use and prompt caching. It provides four specific environment variables necessary for correct gateway integration, including two undocumented ones that disable experimental features and interleaved thinking, which can cause failures with certain upstream providers like Bedrock and Vertex AI. The guide also touches on how AI routers can offer failover capabilities, ensuring uninterrupted service by retrying requests through different model providers. AI
IMPACT Enables developers to reliably integrate Claude Code with AI gateways for enhanced functionality and failover.
