摘要
本技术报告介绍了EXAONE 4.0，它集成了非推理模式与推理模式，旨在同时实现EXAONE 3.5的卓越易用性和EXAONE Deep的高级推理能力。为迎接智能体AI时代，EXAONE 4.0引入了关键特性，如智能体工具使用，并扩展了多语言支持，除英语和韩语外，新增了西班牙语。EXAONE 4.0模型系列包含两种规模：一款中型32B模型，专为高性能优化；另一款小型1.2B模型，适用于设备端应用。相较于同类开源模型，EXAONE 4.0展现出更优性能，即便与前沿模型相比也保持竞争力。这些模型已公开发布，供研究使用，可通过https://huggingface.co/LGAI-EXAONE轻松下载。

This technical report introduces EXAONE 4.0, which integrates a Non-reasoning
mode and a Reasoning mode to achieve both the excellent usability of EXAONE 3.5
and the advanced reasoning abilities of EXAONE Deep. To pave the way for the
agentic AI era, EXAONE 4.0 incorporates essential features such as agentic tool
use, and its multilingual capabilities are extended to support Spanish in
addition to English and Korean. The EXAONE 4.0 model series consists of two
sizes: a mid-size 32B model optimized for high performance, and a small-size
1.2B model designed for on-device applications. The EXAONE 4.0 demonstrates
superior performance compared to open-weight models in its class and remains
competitive even against frontier-class models. The models are publicly
available for research purposes and can be easily downloaded via
