Debugging AI applications that utilize multiple large language models presents unique infrastructure challenges compared to single-model prototypes. Failures can manifest in subtle ways beyond simple API errors, such as increased latency, incorrect output formats, or unexpected cost hikes. To effectively manage these issues, developers need comprehensive logging that tracks the entire request lifecycle, including the specific model used, workflow context, token consumption, and cost, enabling them to pinpoint whether a problem lies with a provider, a model, or a specific application workflow.
