Model Card for Phoenix

Phoenix is a model trained using Direct Preference Optimization (DPO) for the german language. Its training procedure follows the process of the alignment-handbook from Huggingface. In contrast to zephyr and notus this model has been trained using german instruction and dpo data. In detail, a german translation of HuggingFaceH4/ultrachat_200k and HuggingFaceH4/ultrafeedback_binarized were created in addition to a series of allready available instruction datasets. The LLM haoranxu/ALMA-13B was used for this. While the mistral model performs really well, it is not really suitable for the german language. Therefore we have used the fantastic LeoLM/leo-mistral-hessianai-7b. Thanks to the new type of training, Phoenix is not only able to compete with the Mistral model from LeoLM but also beats the Llama-70b-chat model in 2 mt-bench categories. This model wouldn't have been possible without the amazing work of Huggingface, LeoLM, openbnb, argilla, the Alma-Team and many others of the AI community. i would like to personally thank all AI researchers who make the training of such models possible

MT-Bench-DE Scores

Phoenix beats the LeoLM-Mistral model in all categories except for coding and humanities. Additionally it also Beats LeoLM/Llama-2-70b-chat in roleplay and reasoning which shows the power of DPO.

Training Details

Training Hardware

We used a VM with 8 x A100 80GB hosted in Runpods.io.

Training Data

We used a new translated version of HuggingFaceH4/ultrachat_200k, and argilla/ultrafeedback-binarized-preferences.

The data used for training will be made public after additional quality inspection.

Prompt template

We use the same prompt template as HuggingFaceH4/zephyr-7b-beta:

<|system|>
</s>
<|user|>
{prompt}</s>
<|assistant|>

It is also possible to use the model in a multi-turn setup

<|system|>
</s>
<|user|>
{prompt_1}</s>
<|assistant|>
{answer_1}</s>
<|user|>
{prompt_2}</s>
<|assistant|>

Usage

You will first need to install transformers and accelerate (just to ease the device placement), then you can run any of the following:

Via generate

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("DRXD1000/Phoenix", torch_dtype=torch.bfloat16, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("DRXD1000/Phoenix")
prompt = [
    {
        "role": "system",
        "content": "", #Not recommended. Phoenix does not react well on system prompts
    },
    {"role": "user", "content": "Erkläre mir was KI ist"},
]
inputs = tokenizer.apply_chat_template(prompt,  return_tensors="pt").to("cuda")
outputs = model.generate(inputs, num_return_sequences=1, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)

Ethical Considerations and Limitations

As with all LLMs, the potential outputs of DRXD1000/Phoenix cannot be predicted in advance, and the model may in some instances produce inaccurate, biased or other objectionable responses to user prompts. Therefore, before deploying any applications of DRXD1000/Phoenix, developers should perform safety testing and tuning tailored to their specific applications of the model. Please see Meta's Responsible Use Guide.
