# Jellyfish-8B
## Model Details
Jellyfish-8B is a large language model equipped with 8 billion parameters.
We fine-tuned the [Meta-Llama-3-8B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct) model using the datasets pertinent to data preprocessing tasks.
The training data include two parts:
* Jellyfish-13B training data
* GPT4 generated reasoning data for data preprocessing tasks.
More details about the model can be found in the [Jellyfish paper](https://arxiv.org/abs/2312.01678).
