# Model Card for Tulu V2.5 DPO 13B - SHP-2
|
18 |
+
|
19 |
+
Tulu is a series of language models that are trained to act as helpful assistants.
|
20 |
+
Tulu V2.5 is a series of models trained using DPO and PPO starting from the [Tulu 2 suite](https://huggingface.co/collections/allenai/tulu-v2-suite-6551b56e743e6349aab45101).
|
21 |
+
This model is trained on the SHP-2 dataset using DPO.
|
22 |
+
|

+

## .Model description
|
28 |
+
|
29 |
+
- **Model type:** One model belonging to a suite of RLHF tuned chat models on a mix of publicly available, synthetic and human-created datasets.
|
30 |
+
- **Language(s) (NLP):** English
|
31 |
+
- **License:** Apache 2.0.
|
32 |
+
- **Finetuned from model:** [meta-llama/Llama-2-13b-hf](https://huggingface.co/meta-llama/Llama-2-13b-hf)
|
33 |
+
|
34 |
+
### Model Sources
|
35 |
+
|
36 |
+
- **Repository:** https://github.com/allenai/open-instruct
|
37 |
+
- **Dataset:** Data used to train this model can be found [here](https://huggingface.co/datasets/allenai/tulu-2.5-preference-data) - specifically the `shp_2` split.
|
38 |
+
- **Model Family:** The collection of related models can be found [here](https://huggingface.co/collections/allenai/tulu-v25-suite-66676520fd578080e126f618).
|
39 |
+
|
40 |
+
## Input Format
|
41 |
+
|
42 |
+
The model is trained to use the following format (note the newlines):
|
43 |
+
```
|
44 |
+
<|user|>
|
45 |
+
Your message here!
|
46 |
+
<|assistant|>
|
47 |
+
```
|
48 |
+
|
49 |
+
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.**
|
50 |
+
We have included a [chat template](https://huggingface.co/docs/transformers/main/en/chat_templating) in the tokenizer implementing this template.
|
51 |
+
|
52 |
+
## Intended uses & limitations
|
53 |
+
|
54 |
+
The model was initially fine-tuned on a filtered and preprocessed of 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.
|
55 |
+
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 dataset mentioned above.
|
56 |
+
|
57 |
+
## Bias, Risks, and Limitations
|
58 |
+
|
59 |
+
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).
|
60 |
+
It is also unknown what the size and composition of the corpus was used to train the base Llama 2 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.

### Training hyperparameters
|
64 |
+
|
65 |
+
The following hyperparameters were used during DPO training:
|
66 |
+
- learning_rate: 5e-07
|
67 |
+
- total_train_batch_size: 32
|
68 |
+
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
|
69 |
+
- lr_scheduler_type: linear
|
70 |
+
- lr_scheduler_warmup_ratio: 0.1
|
71 |
+
- num_epochs: 3.0
|
