摘要
本技術報告介紹了EXAONE 4.0，該版本整合了非推理模式與推理模式，旨在同時實現EXAONE 3.5的卓越易用性與EXAONE Deep的先進推理能力。為迎接代理型AI時代的到來，EXAONE 4.0引入了關鍵特性，如代理工具的使用，並將其多語言能力擴展至支援西班牙語，除原有的英語和韓語外。EXAONE 4.0模型系列包含兩種規模：一個是針對高效能優化的中型32B模型，另一個是專為設備端應用設計的小型1.2B模型。EXAONE 4.0在同等級開源模型中展現出卓越性能，即便與前沿級別模型相比也保持競爭力。這些模型已公開供研究用途，可通過https://huggingface.co/LGAI-EXAONE輕鬆下載。

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
