In Progress AI LangGraph Groq Python

DebateAI

A multi-agent AI debate platform powered by LangGraph, enabling complex multi-role dialogue simulations.

Motivation#

While learning LangGraph, I wanted to build a project that showcases multi-agent collaboration. Debate is an excellent scenario as it requires multiple roles with different stances to respond to each other.

Tech Stack#

Frontend: Next.js + shadcn/ui
Backend: FastAPI + LangGraph
LLM: Groq API (Llama 3.1)
Deployment: Vercel + Railway

Key Features#

Multi-role Debate: Support for pro, con, and moderator roles
Topic Generation: AI-generated debate topics with background info
Real-time Streaming: SSE-based live dialogue streaming
