Model Card for TowerBase-7B-v0.1
Model Details
Model Description
TowerBase-7B is a language model that results from continuing the pretraining of Llama 2 on a mix of 20 billion tokens of monolingual data from non-English languages, and bilingual data. TowerBase-7B-v0.1 is the first model in the series. The resulting model shows improved performance on the supported languages, while maintaining Llama's capabilities on English. It is particularly well-suited for fine-tuning on translation and related tasks: check out TowerInstruct We will release more details in the upcoming technical report.
- Developed by: Unbabel, Instituto Superior Técnico, CentraleSupélec University of Paris-Saclay
- Model type: A 7B parameter model built on top of Llama 2 by continuing pretraining on multilingual data.

Intended uses & limitations
The model is intended for research purposes in the 10 languages it supports. The model is able to perform well on translation and related tasks (e.g., APE, GEC) on a few-shot regime. It can also be fine-tuned to perform these tasks in a zero-shot fashion (see TowerInstruct, as well as other multilingual tasks.
Out-of-Scope Use
The model is not guaranteed to perform well for languages other than the 10 languages it supports.
Bias, Risks, and Limitations
TowerBase-v0.1 has not been aligned to human preferences, so the model may generate problematic outputs (e.g., hallucinations, harmful content, or false statements).
