# Jellyfish-7B
## Model Details
Jellyfish-7B is a large language model equipped with 7 billion parameters.
We fine-tuned the [mistralai/Mistral-7B-Instruct-v0.2](https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.2) model using
a subset of the [Jellyfish-Instruct](https://huggingface.co/datasets/NECOUDBFM/Jellyfish-Instruct)
Jellyfish-7B vs GPT-3.5-turbo wining rate by GPT4 evaluation is 56.36%.
More details about the model can be found in the [Jellyfish paper](https://arxiv.org/abs/2312.01678).

_For GPT-3.5 and GPT-4, we used the few-shot approach on all datasets. However, for Jellyfish models, the few-shot approach is disabled on seen datasets and enabled on unseen datasets._
