EXAONE 4.0融合推理与非推理模式，兼顾易用性与逻辑能力。
EXAONE 4.0: Unified Large Language Models Integrating Non-reasoning and Reasoning Modes
- 双模式设计：非推理模式保易用，推理模式增强逻辑能力。
- 32B与1.2B两版本，分别面向高性能与本地部署场景。
- 支持多语言与工具调用，适合研究与智能体应用开发。
本技术报告介绍EXAONE 4.0，该模型整合了非推理模式与推理模式，兼具EXAONE 3.5的优异可用性与EXAONE Deep的先进推理能力。为迎接智能体时代，EXAONE 4.0引入关键特性如工具调用功能，并将多语言支持扩展至西班牙语，涵盖英语与韩语。模型系列包含两个尺寸：32B中等规模模型优化性能，1.2B小型模型专为设备端应用设计。相比同级别开源模型，EXAONE 4.0表现更优，甚至可媲美前沿模型。模型已公开，科研用途可从https://huggingface.co/LGAI-EXAONE免费下载。
原文摘要 · Abstract (English)
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 https://huggingface.co/LGAI-EXAONE.
