Gaia is a tool that allows users to build neural machine translators (NMT) without any coding. It enables users to train, deploy, and commercialize their own NMT systems with simple click actions. The tool supports multiple languages, including low-resource language pairs, and offers real-time monitoring features to help users track training progress and performance metrics. Additionally, Gaia provides an easy-to-integrate API, making it convenient for developers to combine trained models with their own systems.
