How Sakana AI’s new evolutionary algorithm builds powerful AI models without expensive retraining
September 1, 2025
A new evolutionary technique from Japan-based AI lab Sakana AI enables developers to augment the capabilities of AI models without costly training and fine-tuning processes. The technique, called Model Merging of Natural Niches (M2N2), overcomes the limitations of other model merging methods and can even evolve new models entirely from scratch.
M2N2 can be applied to different types of machine…
