Build a Reasoning AI Chatbot with Arcee AI Trinity Mini + Gradio + OpenRouter

I just built a chatbot that shows you exactly how the AI thinks. Using Arcee AI’s Trinity Mini model, I created a dual-panel interface in which the reasoning process is displayed in real time above the chat response. This makes the AI’s decision-making transparent—you can watch it work through problems step by step before it delivers the final answer.

The implementation uses Gradio 6.x for the web interface, OpenRouter API for model access, and streaming support for real-time responses. Built entirely with Cursor in Plan and Build Modes, the project demonstrates how modern AI development tools can accelerate the development of transparent AI applications. Features include token limit controls, conversation history, and sample prompts for exploring the model’s capabilities. It’s a practical example of making AI reasoning visible and understandable.
