Mergekit solves the problem of combining multiple fine-tuned language model checkpoints into a single better generalist without needing additional training.
Ask the AI to merge your checkpoints into an output directory by running mergekit on a SLERP YAML config file (e.g., mergekit-yaml slerp_merge.yaml ./merged-model --copy-tokenizer).

You can merge multiple fine-tuned LLM checkpoints into a single fused model without gradient-based training by using mergekit. It applies model fusion workflows like SLERP, TIES, DARE, and Task Arithmetic to combine specialist capabilities into a generalist checkpoint via a YAML configuration.
Yes, you can combine language model checkpoints on a CPU without a GPU. Mergekit supports GPU-free model fusion for many merge methods, allowing you to create a merged model primarily via CPU workflows to avoid costly retraining.
The best way to merge coding and math specialist models to reduce catastrophic forgetting is using strategies like SLERP, TIES, or DARE. Mergekit balances both abilities in one checkpoint, improving breadth compared to selecting a single fine-tuned model.
To run a SLERP model fusion, execute the mergekit-yaml command on your SLERP YAML config file. You specify the models, weights, merge method, and output directory, for example: mergekit-yaml slerp_merge.yaml ./merged-model --copy-tokenizer.
Yes, mergekit supports Frankenmerge layer stacking and EvoMerge optimization. These methods control how capabilities combine when fusing multiple fine-tuned language model checkpoints into a single generalist model.
Yes, you need compatible base architectures and model formats to merge LoRA or finetune outputs with mergekit. The toolchain requires checkpoints from the same base architecture to successfully combine them into a balanced generalist model.
