## 🚀 What is OktoEngine?

**OktoEngine** is the official execution engine for **OktoScript**—a powerful CLI tool that transforms declarative AI configurations into trained, production-ready models.

### Built for Scale

OktoEngine is engineered to handle:
- ✅ **Models of any size** - From millions to billions of parameters
- ✅ **Complex training pipelines** - Full fine-tuning, LoRA adapters, and more
- ✅ **Production workloads** - Optimized for real-world AI development
- ✅ **Enterprise-grade reliability** - Robust error handling and validation

### Why OktoEngine?

**Traditional Approach:**
```python
# Hundreds of lines of Python code
# Complex configuration management
# Error-prone manual setup
# Difficult to reproduce
```

**With OktoEngine:**
```okt
PROJECT "MyModel"
MODEL { base: "gpt2" }
DATASET { train: "dataset/train.jsonl" }
TRAIN { epochs: 5, batch_size: 32 }
EXPORT { format: ["okm"] }
```

**One command:** `okto train` → **Trained model ready for deployment**
