Thesys
Why Choose Thesys?
If ur building AI powered tools where the output needs to be interactive like charts or forms instead of boring plain text, C1 by Thesys is prob the best choice. Most devs spend too much time connecting LLM responses to frontend widgets but this API handles the UI generation directly so you can ship rich apps way faster. Integration is crazy simple takes just 2 lines of code which saves a massive amount of boilerplate work. The real strength here is cutting down that UI overhead almost entirely allowing you to focus on the logic not the CSS. However keep in mind its kinda specialized so if you are building a simple FAQ bot or a static landing page it might be overkill. Its great for dynamic interfaces but you do pay a premium for that flexibility compared to just handing off text responses.
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.
Thesys Introduction
What is Thesys?
Thesys C1 is a Generative UI API that lets LLMs send out interactive components like charts and forms insted of just plain text. Its really made for devs who wanna stop wasting time hand-coding interfaces for every new AI feature. You plug it in with only a few lines of code and suddenly your models can render real ui components live, shaving off most of the UI overhead and letting you move way faster on the actual app logic.
How to use Thesys?
Alright so first things first, you gotta head to Thesys to grab an account and get your API key. once you have that, just drop the SDK into your project using whatevr package manager you use. its pretty straightforward setup really, no crazy config files or anything complex. mostly just making sure you store those credentials safely so they dont end up in git or somthing. Next step is where the magic happens. Instead of writing all the HTML/CSS yourself, you just wrap your LLM calls with this library. I think its literally around 2 lines of code depending on how your setup is. You pass in the prompt like normal, but now instead of getting raw text back, the model starts spitting out structured UI stuff like charts or forms. Once you fire up the app, you should see actual interactive elements pop up instead of static paragraphs. I tested it with a simple query and got a nice card layout instatly. its kinda wild seeing the AI build the interface itself without needing a frontend dev on hand. basically just iterate on your prompts until the UI looks right for your users.
