Kolibrify is a lightweight 'library' (just a couple of simple scripts) designed for curriculum and general fine-tuning of large language models (LLMs) for instruction following. Building on the premise of ChatML format, popularized by OpenAI, it allows for easy compatibility with existing serving frameworks. Key features include support for LoRA/QLoRA fine-tuning, datasets mixing and multi-stage continual training. Kolibrify aims to streamline the process of adapting LLMs to specific tasks or datasets employing curriculum learning for best results.
Kolibrify leverages the power of Unsloth for accelerated model training and reduced memory usage, making it a practical choice for developers looking to fine-tune LLMs with limited compute.
Note
This project serves as a foundation for my research on curriculum learning. It has a unique setup in that it doesn't directly load datasets from Hugging Face, instead relying on local files. As a result, you'll need to download the datasets and save them on your machine to use Kolibrify. I designed it this way to facilitate rapid prototyping, as frequent data processing and pushing datasets to the hub slows down progress. By default, it assumes the use of the ChatML template, although I plan to add support for other templates in the near future.

Kolibrify is equipped with four primary scripts for training, merging and testing fine-tuned models:
kolibrify-train- finetuning.kolibrify-merge- merging lora adapters.kolibrify-predict- generating predictions using a finetuned model.kolibrify-eval-ifeval- evaluating a finetuned model using instruction-following eval. To run those you have to make a YAML configuration file based on thetraining_config_template.yaml, tailored to your project's needs.
Below is a brief rundown regarding each command. See the examples folder for detailed explanations.
To start training, ensure your dataset is in the JSONL format specified, with records like {"messages": [{"role": "role", "content": "content"}]}. Adjust training_config.yaml as necessary, specifying model and dataset paths among other parameters.
kolibrify-train training_config.yamltraining_config.yaml: Path to your training configuration file, detailing model specifications, dataset locations, and training parameters.
Note
See examples folder for a full example of finetuning Mistral model with Kolibrify on Dolphin dataset.
After training, use the merge script to incorporate the fine-tuned LoRA parameters back into the base model. This step is necessary for deploying your fine-tuned model with vLLM (and other serving frameworks).
kolibrify-merge training_config.yamltraining_config.yaml: Path to your training configuration file used during the fine-tuning process.
The model will be saved in the merged folder where your adapter was saved.
For generating predictions with a fine-tuned model, use kolibrify-predict. Specify the path to your configuration, input dataset, and output location for the results:
kolibrify-predict config.yaml /path/to/dataset /path/to/output --gpus 1,2,3config.yaml: Configuration file used during model training./path/to/dataset: Can be a path to a JSONL file or a directory containing multiple JSONL files./path/to/output: Output path for saving the model's predictions. If/path/to/datasetis a JSONL file,/path/to/outputmust be a JSONL as well. The same goes for a path to a folder with datasets.--gpus: Comma-separated GPU indices to use for the evaluation.
For instruction following evaluation, use kolibrify-eval-ifeval. It allows evaluating the model's performance in following instructions in either English or Russian:
kolibrify-eval-ifeval config.yaml --eval-lang en --gpus 1,2,3config.yaml: Configuration file specifying paths and model details.--eval-lang: Language for the evaluation (enfor English,rufor Russian).--gpus: Comma-separated GPU indices to use for the evaluation.
This script will evaluate the model using the Instruction-Following Eval benchmark and save results and logs to the specified output directories.
See training_config_template.yaml for a comprehensive list of adjustable parameters tailored to your training and fine-tuning needs. This includes model identifiers, dataset paths, LoRA parameters, training iterations, learning rate, and more, providing a flexible foundation for model adaptation.
Note
This project is in early development stages and will be updated frequently. If you encounter bugs or would like it to support some specific features, kindly make a corresponding issue. Contributions are welcome.
Note
If possible, kindly provide the kolibrify config you used in your model's repo so that others can reproduce your results.
Huge thanks to the Unsloth team for their amazing project that enabled me to do this research with limited resources at larger scales!
