EXAONE 4.5

LG AI ResearchOpen WeightsPending Human Review

EXAONE 4.5 is LG AI Research’s first open-weight vision-language model, combining a 33B total parameter architecture with a 1.2B vision encoder. It extends the EXAONE family into image understanding, technical documents, charts, and multilingual visual reasoning, with a 256K context window. The release publishes deployment code and evaluation information alongside weights. Its custom EXAONE license must be consulted for usage rights rather than treating the model as Apache-licensed. It is suited to research and domain-specific document assistants, while the actual reliability of extracted facts and visual reasoning requires application-level validation.
