Model Description

<!-- Provide a longer summary of what this model is. -->

Helium-1 is a lightweight language model with 2B parameters, targeting edge and mobile devices. It supports the 24 official languages of the European Union.

⚠️ Helium-1 is a base model, which was not fine-tuned to follow instructions or human preferences. For most downstream use cases, the model should be aligned with supervised fine-tuning, RLHF or related methods.

Uses

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

Direct Use

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->

The intended use of the Helium model is research and development of natural language processing systems, including but not limited to language generation and understanding. The model can be used in Bulgarian, Czech, Danish, German, Greek, English, Spanish, Estonian, Finnish, French, Irish, Croatian, Hungarian, Italian, Lithuanian, Latvian, Maltese, Dutch, Polish, Portuguese, Romanian, Slovak, Slovenian, Swedish. For most downstream use cases, the model should be aligned with supervised fine-tuning, RLHF or related methods.

Out-of-Scope Use

<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->

The model should not be used in other languages than the ones on which it was trained. The model is not intended to be used for any malicious or illegal activities of any kind. The model was not fine-tuned to follow instructions, and thus should not be used as such.

Bias, Risks, and Limitations

Helium-1 is a base language model, which was not aligned to human preferences. As such, the model can generate incorrect, biased, harmful or generally unhelpful content. Thus, the model should not be used for downstream applications without further alignment, evaluations and mitigations of risks.

How to Get Started with the Model

Use the code below to get started with the model.

import torch
from transformers import pipeline

model_id = "kyutai/helium-1-2b"

pipe = pipeline(
    "text-generation",
    model=model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

text = pipe("Hello, today is a great day to")

Training Details

Training Data

Helium-1 was trained on data from Common Crawl, which was preprocessed with the dactory library.
