🤖 LLM Evolutionary Merge

🤗 Model | 📂 Github | ✍️ Blog | 💡Inspired by Sakana AI

robot This project aims to optimize model merging by integrating LLMs into evolutionary strategies in a novel way. Instead of using the CMA-ES approach, the goal is to improve model optimization by leveraging the search capabilities of LLMs to explore the parameter space more efficiently and adjust the search scope based on high-performing solutions.

Currently, the project supports optimization only within the Parameter Space, but I plan to extend its functionality to enable merging and optimization in the Data Flow Space as well. This will further enhance model merging by optimizing the interaction between data flow and parameters.

Performance

I focused on creating a high-performing Korean model solely through merging, without additional model training.
