**📣 Tucanos are fun, but we also want to help build tools for other languages! New releases of the Tucano project, as well as new resources for other low-resource languages, will soon be available in our new organization: [Polyglot](https://huggingface.co/Polygl0t)! Polyglot is a research project from the [University of Bonn](https://www.uni-bonn.de/en), where we seek to aid in the development of foundation models for low-resource languages. So, if you like Tucanos, go follow Polyglot to stay updated with our new releases. 📣**
