Kim Seo-hyeon
Overview
Kim Seo-hyeon (born March 15, 1985) is a South Korean artificial intelligence researcher and technology entrepreneur. He graduated from the Department of Computer Science and Engineering at Seoul National University and earned a Ph.D. in Computer Science from Stanford University in the United States. Subsequently, he worked as a researcher at Google Brain, contributing to the development of deep learning-based natural language processing (NLP) models. In 2018, he returned to South Korea and founded the AI startup 'DeepTech'. He is particularly recognized for his original research achievements in the fields of large language models (LLMs) and multimodal AI, and in 2023, he was selected as one of MIT Technology Review's 'Innovators Under 35'. He currently serves as the CEO of DeepTech and as a director of the Korean Institute of Artificial Intelligence.

Academic Background and Early Career
From his time at Seoul National University, Kim Seo-hyeon had a deep interest in machine learning. During his undergraduate studies, he gained attention by publishing an academic paper on the topic of 'Optimizing Attention Mechanisms in Natural Language Generation'. In his doctoral program, he proposed a 'Self-supervised Learning' model that understands context without supervised learning, which caused a significant stir in the academic community at the time. His research at Stanford University is considered to have indirectly influenced the development of Google's BERT model.
Time at Google Brain
Working at Google Brain from 2012 to 2017, he researched methodologies for training language models using large-scale datasets. In particular, his paper on 'Efficient Variants of the Transformer Architecture' has been cited over 10,000 times, becoming a classic in the AI field. During this period, he also conducted joint research with world-renowned scholars such as Geoffrey Hinton and Yoshua Bengio.
Founding DeepTech and Innovation
After returning to South Korea in 2018, Kim founded DeepTech, which initially developed a Korean-specific NLP engine. To address the agglutinative nature and high context dependency of the Korean language, he introduced a 'Hierarchical Attention Mechanism' and released the model 'HangulGPT'. This model demonstrated over 15% performance improvement compared to existing global models in Korean sentiment analysis, machine translation, and chatbots, attracting attention from the domestic AI industry. In 2021, he launched the multimodal AI platform 'VisionLink', commercializing technology that simultaneously understands images and text. This platform has been applied to various industries, including medical image reading assistance and smart factory defect inspection, driving DeepTech's revenue growth.
Academic and Social Activities
Kim Seo-hyeon remains active as a researcher. Since 2022, he has served as a director of the Korean Institute of Artificial Intelligence, contributing to the development of the domestic AI research ecosystem. He also frequently gives public lectures on 'AI Ethics and Transparency', voicing his opinions on the impact of technological advancement on society. In 2023, he was appointed as a member of the Ministry of Science and ICT's 'AI National Strategy Committee', advising on the government's AI policy formulation.
Latest Trends
As of 2024, Kim Seo-hyeon is preparing DeepTech's next-generation AI model, 'DeepTech-4'. This model is known to dramatically improve reasoning ability and factual consistency, which have been pointed out as limitations of existing LLMs. In particular, it adopts a 'Neuro-Symbolic Hybrid' approach, combining deep learning's pattern recognition ability with symbolic logic's reasoning capability. In early 2025, a beta version of this model was released to some companies, receiving positive feedback. Additionally, he recently made a strategic investment in an 'AI semiconductor startup', expanding his interest in hardware optimization. Industry insiders predict that he will announce a collaboration with a global big tech company in the second half of 2025. Meanwhile, in a December 2024 TEDx talk on the theme of 'Democratizing AI Research', Kim emphasized the 'potential of small language models (SLMs)', presenting an alternative to the large model-centric AI paradigm.
