EXAONE 3.5 is a series of bilingual (English and Korean) instruction-tuned generation models developed by LG AI Research, with parameters ranging from 2.4B to 32B. These models support long-context processing of up to 32K tokens and demonstrate state-of-the-art performance in real-world use cases and long-context understanding, while remaining competitive in general domains when compared to recently released models of similar size. The EXAONE 3.5 model series includes: 1) 2.4B model, optimized for deployment on small or resource-constrained devices; 2) 7.8B model, which matches the size of previous models but offers improved performance; 3) 32B model, providing robust performance.
