+ # 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
+
23
+ For more details, read the paper:
24
+ [Unpacking DPO and PPO: Disentangling Best Practices for Learning from Preference Feedback](https://link.todo).

27
+ ## .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.
61
+
62
+
63
+ ### 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
