EXAONE 3.5 is a series of instruction-tuned bilingual (English and Korean) generative 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 compared to similarly sized models released recently. The EXAONE 3.5 models include: 1) the 2.4B model, optimized for deployment on small or resource-constrained devices; 2) the 7.8B model, matching the size of predecessor models but offering improved performance; 3) the 32B model, providing powerful performance.
