News Highlights:
- C1 by Thesys – the world’s first Generative UI API
- Teams can leverage Generative UI to accelerate product design, reducing costs and enhancing development speed
- Enterprises can now effortlessly create custom interfaces by replacing their existing LLMs or visualizing internal data directly through Thesys C1
C1 by Thesys is the world’s first API built for Generative User Interface (GenUI), enabling developers to turn LLM outputs into live, dynamic applications in real time. It marks a significant breakthrough in how AI-powered interfaces are designed and deployed, reducing complexity and accelerating development across the board.
Enterprises today are racing to adopt AI, yet building the frontend for AI agents remains a major hurdle. Teams spend months and significant resources designing and coding interfaces - only to deliver static, inconsistent, and often disengaging user experiences. Despite the investment, users are left with command-line-like interactions, limiting the promise of AI.
Generative UI changes this completely. Instead of designing screens manually, GenUI allows AI to generate beautiful, interactive interfaces in real time. It doesn't just make front-end development faster and more efficient - it reimagines engagement by creating fresh, adaptive experiences for every individual user.
“For many enterprises, the front-end has long been a bottleneck in deploying AI at scale,” said Rabi Shanker Guha, co-founder, CEO of Thesys. “C1 integrates seamlessly with modern frameworks and languages, abstracting away UI complexity enabling teams to focus on the hardest problems. Enterprises adopting C1 see significantly accelerated product launches, optimized resource allocation, and measurable cost reductions.”
Designed for seamless integration, Thesys works effortlessly with most modern tech stacks. Whether teams are building AI agents from the ground up or enhancing existing systems, Thesys enables them to adopt Generative UI without overhauling their infrastructure.
Highlighting the impact of GenUI on human-computer interaction, Parikshit Deshmukh, co-founder, President of Thesys, added: “AI is making software smart - and smart software deserves a smarter interface. Imagine if every app you opened was tailored just for you, in that moment - that’s the power of Generative UI. It’s the biggest shift since the advent of graphical user interfaces.”
C1 by Thesys is now available for general use. Over 300 teams — from early-stage startups to established enterprises — are already using Thesys tools to design and deploy adaptive AI interfaces. Backed by a team of former Google, Stripe and Salesforce employees, Thesys is actively partnering with startups and enterprises to accelerate the development of AI-native software.
