• [2023.05.25] The preprint of our paper is here.
• [2023.05.25] Bactrian-X llama-7b-lora, llama-13b-lora, bloom-7b1-lora are available.
• [2023.04.22] Release of data in 52 languages here.

Overview

Bactrian-X dataset contains 3.4M pairs of instructions and responses in 52 languages. The instructions were obtained from alpaca-52k, and dolly-15k, and tranlated into 52 languages (52 languages x 67k instances = 3.4M instances). The responses in 52 languages were generated from gpt-3.5-turbo model.

Bactrian-X models are a series of LLM models fine-tuned (using low-rank adaptation/LoRA) on Bactrian-X dataset.

Usage and License Notices: Bactrian-X is intended and licensed for research use only. The dataset is CC BY NC 4.0 (allowing only non-commercial use) and models trained using the dataset should not be used outside of research purposes.

Dataset

We curate our Bactrian instruction dataset with the following steps:

1. Collecting English instructions: The English instructions are obtained from alpaca-52k and dolly-15k, and they are saved to instructions.json.
2. Translating the English instructions into foreign languages: The instructions (and the corresponding inputs, if any) are translated into 51 languages using the Google Translate API (conducted in April 2023).
3. Generating the responses: We generate output from gpt-3.5-turbo for the instructions in each language (conducted in April 2023).

Models

With our dataset and Low-Rank Adaptation (LoRA), we present a family of multilingual and monolingual models based on LLaMA and BLOOM. Our instruction-tuned multilingual Bactrian-X models are available at:

• MBZUAI/bactrian-x-llama-7b-lora
• MBZUAI/bactrian-x-llama-13b-lora
• MBZUAI/bactrian-x-bloom-7b1-lora

Note: We are continually updating this repository. The number of languages will be more than 52 in the future, and the current models are mostly only 7B in size. We welcome any collaborators who are willing to contribute larger models.

Hands-on Bactrian-X

Setting up the Environment

conda create -n bactrian python=3.9
conda activate bactrian
pip install -r requirements.txt

Training

Models are trained with the following hyperparameters:

Hyper-parameter	Bactrian-X
batch_size	128
num_epochs	4
learning_rate	3e-4
cutoff_len	768
lora_r	64
lora_alpha	16

Below is a command to train a LLaMA-7B adapter with our datasets in specific language(s). Replace <lang_iso> with a list of (one or more) ISO-639-2 language codes separated by commas (e.g., en,zh for English and Chinese), and <your_output_dir> to specify where to store the outputs.

Inference

This is example code that loads both the foundation model and Bactrian LoRA weights from the Hugging Face model hub, and runs a Gradio interface for inference on a specified input.

python generate.py \
    --load_8bit \
    --base_model 'decapoda-research/llama-7b-hf' \
    --lora_weights 'MBZUAI/bactrian-x-llama-7b-lora' \
    --share_gradio 

Checkpoint export

To merge the LoRA weights back into the base model for export to Hugging Face format and to PyTorch state_dicts, go to Alpaca-LoRA. This should help users who want to run inference in projects like llama.cpp or alpaca.cpp.
