EXAONE 4.0

LG AI ResearchOpen WeightsPending Human Review

EXAONE 4.0 is LG’s hybrid reasoning family with ordinary and thinking modes. The 32B checkpoint combines local and global attention, while the 1.2B tier targets lower-resource use. It supports Korean, English, and additional languages, tool calls, and long-context understanding. Public weights and deployment instructions support private evaluation, but the custom license governs commercial use. Benchmark comparisons should preserve checkpoint size, thinking mode, and evaluation protocol.
