At standup, a dev wants one unified API to call many different LLM providers' models without separate integrations. Which service fits?
OpenRouter provides a unified API that routes requests to many different underlying LLM providers and models, so an application can call multiple providers through one consistent interface. This avoids maintaining separate SDK integrations per vendor. It is designed specifically for multi-provider flexibility.

During a design review, the team wants requests to automatically fall back to a different provider if the primary one is down. Which OpenRouter feature fits?
OpenRouter supports automatic fallback, retrying a request against alternate providers if the first choice is unavailable or rate-limited, improving reliability without custom failover code. This routing logic is a core value proposition of the aggregator model. It reduces the operational burden of handling per-provider outages.

In a code review, a dev compares per-token pricing across models before choosing one for a feature. Which OpenRouter feature supports this?
OpenRouter exposes a unified pricing view across the many models it proxies, letting developers compare cost and capability before choosing a model for a given feature. This transparency simplifies model selection decisions. It is especially useful when evaluating tradeoffs between cheaper and more capable models.

An incident report shows a request silently used a different model than expected due to a routing rule. What should the team review?
Because OpenRouter can apply routing rules including fallbacks, an unexpected model being used usually traces back to how those rules or model identifiers were configured in the request. Reviewing the routing configuration clarifies why a different model was selected. Being explicit about model preferences avoids this kind of surprise.

During a PR review, a teammate asks the main tradeoff of using an aggregator like OpenRouter instead of calling a provider directly. What is it?
Using an aggregator like OpenRouter introduces an additional dependency and abstraction layer between the app and the model provider, in exchange for easier multi-provider flexibility and built-in resilience. Teams weigh this added indirection against the operational simplicity it provides. This is a classic build-vs-buy consideration in infrastructure design.
