Model Card for Llama 3.1 Tulu V2 70B
Tulu is a series of language models that are trained to act as helpful assistants. Llama 3.1 Tulu V2 70B is a fine-tuned version of Llama 3 that was trained on a mix of publicly available, synthetic and human datasets.
For more details on the training mixture, read the paper: Camels in a Changing Climate: Enhancing LM Adaptation with Tulu 2 .
Note this model is finetuned from Llama 3.1, released under the Meta Llama 3.1 community license, included here under llama_3_license.txt.

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, which contains a diverse range of human created instructions and synthetic dialogues generated primarily by other LLMs.
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 for an example of this.
Training hyperparameters
The following hyperparameters were used during training:
- learning_rate: 1e-05
- total_train_batch_size: 128
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
- lr_scheduler_type: linear
- lr_scheduler_warmup_ratio: 0.03
- num_epochs: 2.0
