GEITje 7B ultra

A conversational model for Dutch, aligned through AI feedback.

This model is a fine-tuned version of BramVanroy/GEITje-7B-ultra-sft on a synthetic DPO dataset of around 56M tokens that was generated with gpt-4-turbo and Rijgersberg/GEITje-7B-chat for Dutch.

Model description

This is a Dutch instruction/chat model ultimately based on Mistral and aligned with AI feedback via DPO. It is a DPO continuation of the SFT trained BramVanroy/GEITje-7B-ultra-sft, which in turn is based on Rijgersberg/GEITje-7B, which in turn is based on Mistral 7B and further pretrained on Dutch data. In (rather naive) benchmarks it outperforms all the original GEITje models on average (but barely). However, note that these benchmarks should be taken with a massive grain of salt (see the disclaimer below the benchmarks on that page). The best evaluation is to try the models and see for yourself.

Usage

One-off:

python

from transformers import pipeline, Conversation

# load_in_8bit: lower precision but saves a lot of GPU memory
# device_map=auto: loads the model across multiple GPUs
chatbot = pipeline("conversational", model="BramVanroy/GEITje-7B-ultra", model_kwargs={"load_in_8bit": True}, device_map="auto")

start_messages = [
    {"role": "system", "content": "Je bent een grappige chatbot die Bert heet. Je maakt vaak mopjes."},
    {"role": "user", "content": "Hallo, ik ben Bram. Ik wil vanavond graag een film kijken. Heb je enkele suggesties?"}
]
conversation = Conversation(start_messages)
conversation = chatbot(conversation)
response = conversation.messages[-1]["content"]
print(response)

Interactive conversation:

python

from transformers import pipeline, Conversation

# load_in_8bit: lower precision but saves a lot of memory
# device_map=auto: loads the model across multiple GPUs
# attn_implementation: uses flash attention, if your device supports it - otherwise remove it
chatbot = pipeline("conversational", model="BramVanroy/GEITje-7B-ultra", model_kwargs={"load_in_8bit": True, "attn_implementation": "flash_attention_2"}, device_map="auto")

while (system_message := input("System message ('q' to quit): ")) != "q":
    start_messages = [
        {"role": "system", "content": system_message},
    ]
    conversation = Conversation(start_messages)
    while (user_input := input("User ('r' to reset): ")) != "r":
        conversation.add_user_input(user_input)
        conversation = chatbot(conversation)
        response = conversation.messages[-1]["content"]
        print("Assistant:", response)

Intended uses & limitations

Although the model has been aligned with gpt-4-turbo output, which has strong content filters, the model could still generate wrong, misleading, and potentially even offensive content. Use at your own risk.

Because the model was trained on synthetic data created with OpenAI/Azure services, this model cannot be used for commercial purposes.

Training and evaluation data

The training data consists of a synthetic dataset based on UltraFeedback binarized created with gpt-4-turbo and geitje-chat. A given prompt, translated from the original dataset, is given to the two models who then generated an answer. Then, gpt-4-turbo is always selected as the best answer which DPO will optimise for. While this is not completely fair, I did not have the budget to actually have gpt-4 rate both replies. Furthermore, while an impressive model, GEITje chat still seems behind gpt-4-turbo in the testing that I have done.

In total the dataset consists of 56,137,090 tokens (combination of prompt + rejected + chosen) and a test set of 6,178,969 tokens (11.00%).

Training procedure

The great alignment handbook was used for training, with a custom slurm script for compatibility with our cluster. It was trained in full, without LoRA or other adapters.

The model was trained in bfloat16 with flash attention 2 on two nodes of four A100 80GB each for around 11 hours. I thank the Flemish Super Computer for their compute.

For conversational usage, the model relies on the Zephyr chat template, which is compatible with system messages. A small portion of the data of *-sft contained system messages, so it is assumed the model can handle system messages at least a little bit.

In earlier iterations I found that using the alignment handbook's defaults (beta=0.01) led to poor results (hallucinations of random tokens). After investigating, it seems that such a low beta does not work well for this dataset as it gives the model too much room to deviate from its initial base model. After a hyperparameter search and manual analysis of the resulting metrics, I selected the current model as the best one, with a beta of 0.1.
