What is EXAONE 4.0
EXAONE 4.0 is a self-developed hybrid reasoning large model launched by LG AI Research in South Korea. The model combines general natural language processing and advanced reasoning capabilities, and supports Korean, English, and Spanish. The model is divided into a 32B Professional version and a 1.2B On-Device version. The former is based on multiple national-level certification exams and is suitable for highly specialized fields, while the latter is small in size, high in performance, supports local operation, and is suitable for scenarios with high privacy and security requirements. EXAONE 4.0 performs excellently in internationally difficult benchmarks, such as MMLU-Pro 81.8 points and AIME 2025 85.3 points, demonstrating its strong ability to handle complex tasks.
