A simple way to test model fallbacks with RouterBase
Short summary
RouterBase provides an OpenAI-compatible API for testing AI model fallbacks without modifying production code, enabling easy prototyping of routing logic before production deployment. The guide demonstrates primary/fallback model selection using environment variables and includes concrete code examples. Start with low-risk tasks and measure fallback frequency to transform routing experiments into data-driven decisions.
- •RouterBase offers OpenAI-compatible API to test model fallbacks with configurable routing
- •Use environment variables to swap primary and fallback models without code changes
- •Start with low-risk use cases (release notes, ticket summaries) and track which model responds to optimize model strategy
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
