What is Thesys?

Thesys provides the infrastructure layer for Generative UI applications, enabling developers to move beyond text-only AI responses and deliver interfaces that adapt to a user's intent and context. Its OpenUI Cloud, formerly C1 API, sits between an application's LLM layer and frontend and transforms model responses into structured, interactive UI that can be rendered through Thesys's React SDK. Applications can dynamically generate components such as charts, tables, cards, forms, dashboards and other interactive experiences. OpenUI Cloud is OpenAI-compatible and supports tool calling, streaming and real-time UI rendering, while the platform remains model-agnostic and can work with models from providers such as OpenAI and Anthropic. Thesys also offers a Reports API for generating slides and reports.
