Multi-Model Fallback Playbook for Reliable AI APIs
A practical architecture for retrying providers, switching models and protecting quality without creating an uncontrolled fallback chain.
Retry the same route only for transient failures such as timeouts and 429 responses.
Fail over to a model that satisfies the same capability and output-contract requirements.
Set a maximum cost and latency budget for the entire request, not for each attempt.
Log provider, model, error class, retry count and final route for every request.
