NEW Adding a Web UI with AG-UI and CopilotKit

Adding a Web UI with AG-UI and CopilotKit

Your Spring AI application can chat with an LLM, but what if you want to take that conversation out of the terminal and into a web browser? With AG-UI and CopilotKit, you can give your Spring AI application a polished, ChatGPT-like interface with surprisingly little code.

NEW Fact-Checking with a System One Model

Fact-Checking with a System One Model

LLM-as-a-Judge is a powerful evaluation technique, but what if you don't need another LLM to make the call? With a System One model, you can fact-check AI responses using focused, typed judgments with less latency and lower cost.

NEW Running System One Models Locally

Running System One Models Locally

System One models can make fast, focused judgments without calling on a general-purpose LLM. And with models like Nimble and Laya, you can bring that decision-making power entirely onto your local machine.
