Multi-model AI routing infrastructure for developers, chatbots, and enterprises
Provide a single API that lets customers select among multiple AI models, route requests based on availability, normalize model options, and automatically fall back when a model is unavailable. The strongest initial niches are developer tools and chatbots, with enterprise demand driven by the desire for a plan B instead of relying on one frontier-model provider.

Problem: Customers otherwise have to integrate and manage many model providers separately, while high-reasoning business workflows risk inconsistent outputs and model drift when requests are routed across too many models.
For: Developers building model-enabled tools, chatbot operators, and enterprises that want to switch between or maintain fallback access to multiple AI models.
