Model Description

Lucie-7B-Instruct-v1.1 is a fine-tuned version of Lucie-7B, an open-source, multilingual causal language model created by OpenLLM-France. It is meant to replace the original Lucie-7B-Instruct model that was released in January 2025.

Lucie-7B-Instruct is fine-tuned on a mixture of human-templated and synthetic instructions (produced by ChatGPT) and a small set of customized prompts about OpenLLM and Lucie.

Note that this instruction training is light and is meant to allow Lucie to produce responses of a desired type (answer, summary, list, etc.). Lucie-7B-Instruct-v1.1 would need further training before being implemented in pipelines for specific use-cases or for particular generation tasks such as code generation or mathematical problem solving. It is also susceptible to hallucinations; that is, producing false answers that result from its training. Its performance and accuracy can be improved through further fine-tuning and alignment with methods such as DPO, RLHF, etc.

Due to its size, Lucie-7B is limited in the information that it can memorize; its ability to produce correct answers could be improved by implementing the model in a retrieval augmented generation pipeline.

While Lucie-7B-Instruct is trained on sequences of 4096 tokens, its base model, Lucie-7B has a context size of 32K tokens. Based on Needle-in-a-haystack evaluations, Lucie-7B-Instruct-v1.1 has a context window size of 22K tokens. This window could be increased by fine-tuning on longer data samples.

Training details

Training data

Lucie-7B-Instruct-v1.1 is trained on the following datasets:

• Alpaca-cleaned-fr (French; 51,655 samples)
• Croissant-Aligned-Instruct (English-French; 20,000 samples taken from 80,000 total)
• ENS (French, 394 samples)
• FLAN v2 Converted (English, 78,580 samples)
• Open Hermes 2.5 (English, 1,000,495 samples)
• Oracle (French, 4,613 samples)
• PIAF (French, 1,849 samples)
• TULU3 Personas Math
• TULU3 Personas Math Grade
• Wildchat (French subset; 26,436 samples)
• Hard-coded prompts concerning OpenLLM and Lucie (based on allenai/tulu-3-hard-coded-10x)
  • French: openllm_french.jsonl (24x10 samples)
  • English: openllm_english.jsonl (24x10 samples)

One epoch was passed on each dataset except for Croissant-Aligned-Instruct for which we randomly selected 20,000 translation pairs.

Preprocessing

• Filtering by keyword: Examples containing assistant responses were filtered out from the four synthetic datasets if the responses contained a keyword from the list filter_strings. This filter is designed to remove examples in which the assistant is presented as model other than Lucie (e.g., ChatGPT, Gemma, Llama, ...).

Instruction template:

Lucie-7B-Instruct-v1.1 was trained on the chat template from Llama 3.1 with the sole difference that <|begin_of_text|> is replaced with <s>. The resulting template:

<s><|start_header_id|>system<|end_header_id|>

{SYSTEM}<|eot_id|><|start_header_id|>user<|end_header_id|>

{INPUT}<|eot_id|><|start_header_id|>assistant<|end_header_id|>

{OUTPUT}<|eot_id|>

An example:

<s><|start_header_id|>system<|end_header_id|>

You are a helpful assistant.<|eot_id|><|start_header_id|>user<|end_header_id|>

Give me three tips for staying in shape.<|eot_id|><|start_header_id|>assistant<|end_header_id|>

1. Eat a balanced diet and be sure to include plenty of fruits and vegetables. \n2. Exercise regularly to keep your body active and strong. \n3. Get enough sleep and maintain a consistent sleep schedule.<|eot_id|>

Training procedure

The model architecture and hyperparameters are the same as for Lucie-7B during the annealing phase with the following exceptions:

• context length: 4096*
• batch size: 1024
• max learning rate: 3e-5
• min learning rate: 3e-6

*As noted above, while Lucie-7B-Instruct is trained on sequences of 4096 tokens, it maintains the capacity of the base model, Lucie-7B, to handle context sizes of up to 32K tokens.

Testing the model

Test with ollama

• Download and install Ollama
• Download the GGUF model
• Copy the Modelfile, adapting if necessary the path to the GGUF file (line starting with FROM).
• Run in a shell:
  • ollama create -f Modelfile Lucie
  • ollama run Lucie
• Once ">>>" appears, type your prompt(s) and press Enter.
• Optionally, restart a conversation by typing "/clear"
• End the session by typing "/bye".

Useful for debug:

• How to print input requests and output responses in Ollama server?
• Documentation on Modelfile
  • Examples: Ollama model library
    • Llama 3 example: https://ollama.com/library/llama3.1
• Add GUI : https://docs.openwebui.com/

Test with vLLM

1. Run vLLM Docker Container

Use the following command to deploy the model, replacing INSERT_YOUR_HF_TOKEN with your Hugging Face Hub token.

docker run --runtime nvidia --gpus=all \
    --env "HUGGING_FACE_HUB_TOKEN=INSERT_YOUR_HF_TOKEN" \
    -p 8000:8000 \
    --ipc=host \
    vllm/vllm-openai:latest \
    --model OpenLLM-France/Lucie-7B-Instruct-v1.1

2. Test using OpenAI Client in Python

To test the deployed model, use the OpenAI Python client as follows:

from openai import OpenAI

# Initialize the client
client = OpenAI(base_url='http://localhost:8000/v1', api_key='empty')

# Define the input content
content = "Hello Lucie"

# Generate a response
chat_response = client.chat.completions.create(
    model="OpenLLM-France/Lucie-7B-Instruct-v1.1",
    messages=[
        {"role": "user", "content": content}
    ],
)
print(chat_response.choices[0].message.content)
