What is EXAONE?

EXAONE is a cutting-edge language model developed by LG AI Research, aimed at fostering "Expert AI" in multiple disciplines. To bolster EXAONE's capabilities, the Expert AI Alliance was formed, uniting leading companies from various industries for collaborative efforts. These partner organizations will serve as mentors, providing their knowledge, skills, and data to help EXAONE excel in targeted areas. Similar to a college student who has completed their general studies, EXAONE needs specialized training to achieve true mastery in specific fields. LG AI Research has already demonstrated the potential of EXAONE through real-world applications, such as Tilda, an AI human artist that premiered at New York Fashion Week, and AI tools that efficiently summarize customer service interactions and extract valuable insights from complex academic texts. This initiative underscores not only the innovative uses of AI technology but also the critical role of collaboration in pushing technological boundaries. Moreover, the ongoing partnerships within the Expert AI Alliance promise to yield even more groundbreaking advancements in the future.
