# AXL — Architecture eXperimental Lab

**27 CPU-Optimized Code Generation Models** by [Cubic](https://cubic.net)

All models are trained from scratch on consumer hardware (AMD Ryzen 5 5600G, 16GB RAM). No GPU required.

## Quick Start

### Python API Server (Full Quality - Recommended)
```bash
pip install -e .
python AXL/API/serve_model.py --model AXL-Micro-Lion/ --port 8880

# OpenAI-compatible endpoint:
curl  \
  -H "Content-Type: application/json" \
  -d '{"prompt": "def fibonacci(n):", "max_tokens": 100}'

# Works with Continue.dev, LlamaIndex, LangChain, Cursor
