Built for teams that need model choice without gateway overhead
A prototype, a support agent and a retrieval application need different routes, controls and outcome tests. Choose the workflow closest to yours to see what KeepRouter supplies and what your application still owns.
Start with your application, agent workflow or team stage. Each guide defines a measurable adoption path, a live catalog check, the application-level evaluation you need and the product boundary to plan around.
AI startups
AI startups use KeepRouter when they need to evaluate and ship models through one managed account without pretending that model behavior is interchangeable. The live catalog, scoped keys, and measured usage turn vendor experiments into reviewable product decisions.
agent builders
Agent builders need more than an endpoint: long loops require model allowlists, spend limits, observable requests, and explicit retry rules. KeepRouter provides those gateway boundaries while your agent remains responsible for tool safety and task completion.
developer tools
Developer tools can expose a reviewed model shortlist through one gateway integration, while keeping protocol and capability differences explicit. Separate scoped keys make environments and product surfaces attributable without distributing provider credentials.
engineering teams
Engineering teams can centralize authentication and prepaid usage while keeping model selection, evaluation, retries, and data policy under application ownership. The goal is a smaller integration surface and clearer evidence—not an invisible universal abstraction.
AI prototyping
A useful prototype separates plumbing from model evaluation. Prove authentication and response parsing with the free model, then run the same bounded task against paid candidates and compare the evidence your product actually needs.
Retrieval and RAG applications
A RAG application needs a stable relationship between its document vectors, query vectors, retrieval index, and answer model. KeepRouter can provide catalog-listed embedding and generation routes, but the application owns its index, relevance tests, citations, and the decision to re-embed when the vector model changes.
Customer support agents
A support agent succeeds when it resolves a permitted case correctly or hands it to a human with enough context. KeepRouter can provide model access, scoped keys and request usage evidence; the application must own customer permissions, knowledge freshness, tool execution, escalation rules and resolution measurement.
