# CoT-Lab: Human-AI Co-Thinking Laboratory
[Huggingface Spaces 🤗](https://huggingface.co/spaces/Intelligent-Internet/CoT-Lab) | [GitHub Repository 🌐](https://github.com/Intelligent-Internet/CoT-Lab)
[中文README](README_zh.md)

**Sync your thinking with AI reasoning models to achieve deeper cognitive alignment**
Follow, learn, and iterate the thought within one turn

## 🌟 Introduction
CoT-Lab is an experimental interface exploring new paradigms in human-AI collaboration. Based on **Cognitive Load Theory** and **Active Learning** principles, it creates a "**Thought Partner**" relationship by enabling:

- 🧠 **Cognitive Synchronization**  
  Slow-paced AI output aligned with human information processing speed
- ✍️ **Collaborative Thought Weaving**   
  Human active participation in AI's Chain of Thought


** This project is part of ongoing exploration. Under active development, discussion and feedback are welcome! **

## 🛠 Usage Guide
### Basic Operation
1. **Set Initial Prompt**  
   Describe your prompy in the input box (e.g., "Explain quantum computing basics")

2. **Adjust Cognitive Parameters**  
   - ⏱ **Thought Sync Throughput**: tokens/sec - 5:Read-aloud, 10:Follow-along, 50:Skim
   - 📏 **Human Thinking Cadence**: Auto-pause every X paragraphs (Default off - recommended for active learning)

3. **Interactive Workflow**  
   - Click `Generate` to start co-thinking, follow the thinking process
   - Edit AI's reasoning when it pauses - or pause it anytime with `Shift+Enter`
   - Use `Shift+Enter` to hand over to AI again

## 🧠 Design Philosophy
- **Cognitive Load Optimization**  
  Information chunking (Chunking) adapts to working memory limits, serialized information presentation reduces cognitive load from visual searching

- **Active Learning Enhancement**  
  Direct manipulation interface promotes deeper cognitive engagement

- **Distributed Cognition**  
  Explore hybrid human-AI problem-solving paradiam 

## 📥 Installation & Deployment
Local deployment is (currently) required if you want to work with locally hosted LLMs. 

**Prerequisites**: Python 3.11+ | Valid [Deepseek API Key](https://platform.deepseek.com/) or OPENAI chat.completions compatible API.

```bash
# Clone repository
git clone https://github.com/Intelligent-Internet/CoT-Lab
cd CoT-Lab

# Install dependencies
pip install -r requirements.txt

# Configure environment
API_KEY=sk-****
API_URL=https://api.deepseek.com/beta
API_MODEL=deepseek-reasoner

# Launch application
python app.py
```

### API Settings for serving
You can set environment variable `API_KEY` to hide the key from frontend.
Only OPENAI chat.completions compatible API is supported now.
