Tools for merging pretrained large language models.

59
/ 100
Established

This tool helps you combine multiple existing large language models into a single, more versatile one without needing to retrain them from scratch. You provide a set of pre-trained models and specify how you want to blend their capabilities, and it outputs a new, merged model. It's designed for AI practitioners, researchers, and hobbyists who want to customize language models efficiently.

6,857 stars. Actively maintained with 1 commit in the last 30 days.

Use this if you want to create a specialized language model by blending the strengths of several existing models, without the computational cost of training or ensembling.

Not ideal if you need to train a language model from raw data or fine-tune an existing model on new data, as this tool focuses solely on merging already trained models.
