Tether AI Research has developed multilingual on-device translation models that support nine European languages through a single multilingual deployment.
The TranslatePsy-EuroNano family is designed to reduce the need for separate bilingual models for every language pair. Using English as a pivot, the deployment enables 90 translation directions across English and nine European languages.
Key details include:
- Smallest deployment tier is 17.6 times smaller than a comparable setup
- Model sizes range from 36MB to 89MB
- Firefox’s equivalent setup requires 18 separate bilingual models totaling 633MB
- Controlled CPU benchmarking showed faster first-sentence translation times for TinyQ and BaseQ
The weights are openly available, and researchers can fine-tune them for domains such as customer support chatbots, virtual assistants, educational tutors, and question-answering systems. The models are also available through QVAC SDK for Android, iOS, Linux, macOS, and Windows.
