## OPT
Meta recently released [Open Pretrained Transformer (OPT)](https://github.com/facebookresearch/metaseq), a 175-Billion parameter AI language model, which stimulates AI programmers to perform various downstream tasks and application deployments.

The following example of [Colossal-AI](https://github.com/hpcaitech/ColossalAI) demonstrates fine-tuning Casual Language Modelling at low cost.

We are using the pre-training weights of the OPT model provided by Hugging Face Hub on the raw WikiText-2 (no tokens were replaced before
the tokenization). This training script is adapted from the [HuggingFace Language Modelling examples](https://github.com/huggingface/transformers/tree/main/examples/pytorch/language-modeling).

## Our Modifications
We adapt the OPT training code to ColossalAI by leveraging Gemini and ZeRO DDP.

## Quick Start
You can launch training by using the following bash script

```bash
bash ./run_gemini.sh
```
