MANAS-1

NeuroDX announces India's first Brain Language Model, MANAS-1. Designed as a Foundation Model for EEGs, MANAS-1 demonstrates SOTA performance across various tasks in BCI and clinical applications. We have released two variants, MANAS-1-small (40M parameters), and MANAS-1-medium (400M parameters).
