## Model Details
|
|||
|
|
|
|||
|
|
The EuroLLM project has the goal of creating a suite of LLMs capable of understanding and generating text in all European Union languages as well as some additional relevant languages.
|
|||
|
|
EuroMoE-2.6B-A0.6B is a 22B parameter model trained on 8 trillion tokens divided across the considered languages and several data sources: Web data, parallel data (en-xx and xx-en), and high-quality datasets.
|
|||
|
|
EuroMoE-2.6B-A0.6B-Instruct was further instruction tuned on EuroBlocks, an instruction tuning dataset with focus on general instruction-following and machine translation.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Model Description
|
|||
|
|
|
|||
|
|
EuroMoE uses a standard MoE Transformer architecture:
|
|||
|
|
- We use grouped query attention (GQA) with 2 key-value heads, since it has been shown to increase speed at inference time while maintaining downstream performance.
|
|||
|
|
- We perform pre-layer normalization, since it improves the training stability, and use the RMSNorm, which is faster.
|
|||
|
|
- We use the SwiGLU activation function, since it has been shown to lead to good results on downstream tasks.
|
|||
|
|
- We use rotary positional embeddings (RoPE) in every layer, since these have been shown to lead to good performances while allowing the extension of the context length.
|
|||
|
|
|
|||
|
|
For pre-training, we use 512 Nvidia A100 GPUs of the Leonardo supercomputer, training the model with a constant batch size of 4096 sequences, which corresponds to approximately 17 million tokens, using the Adam optimizer, and BF16 precision.

## Run the model
|
|||
|
|
|
|||
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer
|
|||
|
|
|
|||
|
|
model_id = "utter-project/EuroMoE-2.6B-A0.6B-Instruct-Preview"
|
|||
|
|
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
|||
|
|
model = AutoModelForCausalLM.from_pretrained(model_id)
|
|||
|
|
|
|||
|
|
messages = [
|
|||
|
|
{
|
|||
|
|
"role": "system",
|
|||
|
|
"content": "You are EuroLLM --- an AI assistant specialized in European languages that provides safe, educational and helpful answers.",
|
|||
|
|
},
|
|||
|
|
{
|
|||
|
|
"role": "user", "content": "What is the capital of Portugal? How would you describe it?"
|
|||
|
|
},
|
|||
|
|
]
|
|||
|
|
|
|||
|
|
inputs = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt")
|
|||
|
|
outputs = model.generate(inputs, max_new_tokens=1024)
|
|||
|
|
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

## Bias, Risks, and Limitations
|
|||
|
|
|
|||
|
|
EuroMoE-2.6B-A0.6B-Instruct-Preview has not been aligned to human preferences, so the model may generate problematic outputs (e.g., hallucinations, harmful content, or false statements).
