## Advantages of StatDetectLLM

- ⚡ **Lightweight and cost-efficient**: Runs entirely on CPU and produces results within seconds, making it suitable for large-scale or resource-constrained deployments.
- 💪 **High detection performance**: Achieves an AUC above 0.99 when detecting text generated by a wide range of state-of-the-art LLMs, including Grok, GPT, and Gemini.
- 🔒 **Statistical guarantees**: Provides rigorous hypothesis-testing guarantees by controlling the test size at a user-specified nominal significance level, while maintaining detection power exceeding 90%.
