Fix your AI bill.
One problem at a time.

Engineering teams shipping AI features typically hit one of four infrastructure problems as their usage grows. The first is cost, paying flagship model prices for requests that simpler models handle just as well. The second is visibility, knowing the total monthly spend but not which feature, task type, or team is responsible for the majority of it. The third is reliability, having a single-provider dependency that turns every OpenAI outage into an application outage. The fourth is routing complexity, wanting to reduce costs but not wanting to build and maintain the routing logic yourself.

PromptUnit addresses all four through a single proxy integration. One base URL change connects your application to the full routing, observability, and failover layer. The solutions below describe each capability in detail, most teams start with cost reduction and add observability and failover as their infrastructure matures.
