The ITER Organization has taken a major step toward accelerating global fusion energy research by releasing the Integrated Modelling & Analysis Suite (IMAS) under open-source licenses on GitHub. IMAS provides powerful, standardized tools for plasma modelling and data analysis—now freely accessible to researchers, developers, and innovators worldwide. This milestone was made possible through broad collaboration across ITER Members and partner institutions, with special thanks to EUROfusion, EURAT
