# How Sakana AI’s new evolutionary algorithm builds powerful AI models without expensive retraining

**[Venture Beat](https://daily.dev/sources/venturebeat)** · 7 min read · 3 upvotes · 0 comments

## Summary

Sakana AI introduces M2N2 (Model Merging of Natural Niches), an evolutionary algorithm that combines multiple specialized AI models into powerful multi-skilled systems without expensive retraining. The technique uses flexible parameter mixing, diversity-based competition, and complementary model pairing to create models that outperform traditional merging methods. M2N2 has been successfully tested on image classifiers, large language models, and text-to-image generators, demonstrating its ability to create hybrid capabilities and even emergent bilingual abilities.
