Multi-Model Debate Engine — Run AI Debates

Overview

The Debate Engine is an open-source framework that runs structured AI debates: multiple expert personas (powered by DeepSeek Chat) analyze a question in parallel, then Gemini 2.5 Pro synthesizes their views into a unified recommendation.

When to Use It

• Complex decisions with no clear right answer (pricing, hiring, market entry)
• When you want multiple expert perspectives in minutes
• When you need to stress-test an idea before presenting it
• Strategy sessions, product prioritization, investor pitch prep

How to Run Locally

```bash

git clone https://github.com/nealkhis/debate-engine

cd debate-engine

pip install httpx

export DEEPSEEK_API_KEY=your_key

export GOOGLE_API_KEY=your_key
