A HuggingFace Spaces demo for Stack 2.9, a pattern-based AI coding assistant powered by Qwen2.5-Coder-7B.
## ✨ Features
- **🤖 Qwen2.5-Coder-7B** - State-of-the-art code generation model
- **🔧 7 Integrated Tools** - File operations, git, web search, shell commands
- **🧠 Pattern Memory** - Learns from each interaction
- **⚡ Fast Streaming** - Real-time token-by-token generation
- **💾 4-bit Quantization** - Runs on 16GB GPU (~4GB VRAM)
## 🔧 Available Tools
| Tool | Description |
|------|-------------|
| `file_read` | Read files from the filesystem |
| `file_write` | Write content to files |
| `git_status` | Check git repository status |
| `web_search` | Search the web for information |
| `run_command` | Execute shell commands |
| `create_directory` | Create new directories |
| `list_directory` | List directory contents |
## 🏃♂️ Quick Start
### Local Development
```bash
# Clone the repository
git clone https://github.com/your-repo/stack-2.9.git
cd stack-2.9/space
# Install dependencies
pip install -r requirements.txt
# Run the demo
python app.py --share
```
### HuggingFace Spaces
1. Create a new Space on [HuggingFace](https://huggingface.co/spaces)
2. Select "Gradio" as the SDK
3. Upload the files from this directory:
- `app.py`
- `requirements.txt`
- `README.md`
4. The model will load automatically on startup
## 💻 Usage
### Example Prompts
```
Hello! What can you help me with?
Check git status of this repository
Search for best practices for Python async programming
List the files in the current directory
Write a simple Python function to calculate fibonacci
How do I use Git to create a new branch?
What's your memory of our conversation?
```
### Python API
```python
from app import StackModel, memory
# Initialize model
model = StackModel()
model.load()
# Generate response
response = model.generate("Write a hello world in Python")
print(response)
# Check memory stats
print(memory.get_stats())
```
## 🔐 Environment Variables
- `HF_TOKEN` - Your HuggingFace token for private models (optional)
- `MODEL_ID` - Override default model (default: Qwen/Qwen2.5-Coder-7B-Instruct)
## 📊 Memory System
Stack 2.9 includes a pattern memory system that:
1. **Tracks Interactions** - Records every user-assistant exchange
2. **Learns Patterns** - Identifies frequently used tools
3. **Stores Code** - Saves useful code snippets
4. **Adapts Behavior** - Uses learned context to improve responses
## 🛠️ Tech Stack
- **Model**: Qwen2.5-Coder-7B-Instruct
- **Quantization**: 4-bit (bitsandbytes)
- **Framework**: Gradio 4.0+
- **Backend**: Transformers + Accelerate
- **GPU**: 16GB VRAM recommended
