# Model Card for Llama 3 Tulu V2+DPO 70B

Tulu is a series of language models that are trained to act as helpful assistants. 
Llama 3 Tulu V2 70B is a fine-tuned version of Llama 3 that was trained on a mix of publicly available, synthetic and human datasets.
It was then further trained using [DPO]((https://arxiv.org/abs/2305.18290) on the [UltraFeedback](https://huggingface.co/datasets/argilla/ultrafeedback-binarized-preferences-cleaned) dataset.

For more details on the training mixture, read the paper: [Camels in a Changing Climate: Enhancing LM Adaptation with Tulu 2
](https://arxiv.org/abs/2311.10702).

**Built with Meta Llama 3!**
Note that Llama 3 is released under the Meta Llama 3 community license, included here under `llama_3_license.txt`.

We also release reward models based off Llama 3 8b and 70b respectively:
- [Llama 3 Tulu 2 8b UltraFeedback RM](https://huggingface.co/allenai/llama-3-tulu-2-8b-uf-mean-rm)
- [Llama 3 Tulu 2 70b UltraFeedback RM](https://huggingface.co/allenai/llama-3-tulu-2-70b-uf-mean-rm)

## Input Format

The model is trained to use the following format (note the newlines):
```
<|user|>
Your message here!
<|assistant|>
```

For best results, format all inputs in this manner. **Make sure to include a newline after `<|assistant|>`, this can affect generation quality quite a bit.**


## Intended uses & limitations

The model was initially fine-tuned on the [Tulu V2 mix dataset](https://huggingface.co/datasets/allenai/tulu-v2-sft-mixture), which contains a diverse range of human created instructions and synthetic dialogues generated primarily by other LLMs. 
We then further aligned the model with a [Jax DPO trainer](https://github.com/hamishivi/EasyLM/blob/main/EasyLM/models/llama/llama_train_dpo.py) built on [EasyLM](https://github.com/young-geng/EasyLM) on the [openbmb/UltraFeedback](https://huggingface.co/datasets/openbmb/UltraFeedback) dataset, which contains 64k prompts and model completions that are ranked by GPT-4. 


## Bias, Risks, and Limitations


The Tulu models have not been aligned to generate safe completions within the RLHF phase or deployed with in-the-loop filtering of responses like ChatGPT, so the model can produce problematic outputs (especially when prompted to do so). 
It is also unknown what the size and composition of the corpus was used to train the base Llama 3 models, however it is likely to have included a mix of Web data and technical sources like books and code. See the [Falcon 180B model card](https://huggingface.co/tiiuae/falcon-180B#training-data) for an example of this.


### DPO Training hyperparameters
