C1 by Thesys is a Generative UI API that augments LLMs to respond with interactive UI like charts, forms, cards, and more in real-time, instead of plain text. It integrates seamlessly with any LLM, framework, or MCP in just 2 lines of code. Ship rich, interactive AI apps 10x faster with 80% less UI overhead.
This is the 4th launch from Thesys. View more

The maker mentioned moving from regenerating charts per turn to "live charts where data can be refreshed." thats a fundamentally different architecture problem, stateless generation vs stateful component lifecycle. How is C1 handling component identity and diffing between turns today?
This is interesting because it shifts the problem from “better prompts” to better outputs. Generative UI feels like the missing layer between LLMs and real products — text is rarely the final interface users want. Curious how you’re handling state + re-renders when responses evolve over time.
How does the No-code builder handle complex logic or multi-step workflows compared to the C1 API?"
How do you see Generative UI evolving compared to traditional static dashboards in the next year?
You’re growing fast, congratulations on the new launch!
The pivot from developer API to no-code agent builder is a smart distribution move, but I'm wondering how you handle the tension between the no-code audience and the c1 api developer audience are these the same buyers or are you splitting focus?
