LG AI Research has introduced “EXAONE 4.0,” Korea’s first hybrid AI model, positioning itself alongside top players like Anthropic and Alibaba in the global AI race. The announcement was made on July 15, ahead of the company’s upcoming “LG AI Talk Concert 2025” to be held on July 22 at LG Science Park in Seoul.
EXAONE 4.0 uniquely combines two core AI capabilities: natural language understanding and generation powered by a large language model, and autonomous reasoning for problem-solving. It can not only respond quickly to knowledge-based queries but also hypothesize, verify, and explain complex ideas—essentially thinking like a human expert.
LG’s new model achieved best-in-class results in multiple benchmark tests. It scored 92.3 and 81.8 in MMLU-Redux and MMLU-Pro (measuring knowledge and reasoning), outperformed rivals in coding (66.7 in LiveCodeBench v6), science (75.4 in GPQA-Diamond), and mathematics (85.3 in AIME 2025)—surpassing open models from Google, Meta, Microsoft, Alibaba, and Mistral.
To ensure broad accessibility, LG has released EXAONE 4.0 as an open-weight model on Hugging Face, allowing the global research community to experiment and build on it.

A Model with Real Expertise—Not Just Language Fluency
EXAONE 4.0 comes in two variants: a 32-billion-parameter expert model and a 1.2-billion-parameter on-device model. The expert version passed six Korean national licensing exams, including for medical doctors and appraisers, demonstrating its practical depth and domain knowledge.
The on-device model is optimized for edge devices like smartphones, home appliances, and vehicles. Despite its compact size, it surpasses OpenAI’s GPT-4o mini in key areas such as math, coding, and science, making it a strong contender in the emerging on-device AI market.

EXAONE Now Available via API
LG has partnered with Friendly AI to launch a commercial API for EXAONE 4.0. Developers and businesses can now access the model without high-end GPUs, making it easier to integrate powerful AI into everyday services.
Earlier this year, LG Corp. CEO Koo Kwang-mo emphasized the company’s vision: “By making advanced technologies like AI accessible in daily life, we aim to create a new lifestyle where people can spend their time on more joyful and meaningful pursuits.”
With EXAONE 4.0, LG not only delivers a technological leap but also signals its determination to lead in the global AI ecosystem—on devices, in research labs, and across industries.
