TowerInstruct-7B is a language model that results from fine-tuning TowerBase on the TowerBlocks supervised fine-tuning dataset. TowerInstruct-7B-v0.1 is the first model in the series. The model is trained to handle several translation-related tasks, such as general machine translation (e.g., sentence- and paragraph/document-level translation, terminology-aware translation, context-aware translation), automatic post edition, named-entity recognition, grammatical error correction, and paraphrase generation. We will release more details in the upcoming technical report. For now, you can check the results obtained with the model here.

• Developed by: Unbabel, Instituto Superior Técnico, CentraleSupélec University of Paris-Saclay
• Model type: A 7B parameter model fine-tuned on a mix of publicly available, synthetic datasets on translation-related tasks, as well as conversational datasets and code instructions.
• Language(s) (NLP): English, Portuguese, Spanish, French, German, Dutch, Italian, Korean, Chinese, Russian

• Finetuned from model: TowerBase

Update: TowerInstruct-7B-v0.2 has more reliable document-level translation capabilities in comparison with TowerInstruct-7B-v0.1. The new version of TowerBlocks used to train v0.2 is also available in the Tower collection.

Note: TowerInstruct-v0.2 was trained using the ChatML prompt templates without any system prompts.

Intended uses & limitations

The model was initially fine-tuned on a filtered and preprocessed supervised fine-tuning dataset (TowerBlocks), which contains a diverse range of data sources:

• Translation (sentence and paragraph-level)
• Automatic Post Edition
• Machine Translation Evaluation
• Context-aware Translation
• Terminology-aware Translation
• Multi-reference Translation
• Named-entity Recognition
• Paraphrase Generation
• Synthetic Chat data
• Code instructions
