GS Caltex has moved to promote digital transformation and the spread of in-house artificial intelligence (AI) technology. It is a strategy to secure a competitive edge in the AI era.
According to the business community on the 22nd, GS Caltex set "digital & AI transformation (DAX·Digital & AI Transformation)," which integrates digital transformation (DX) and AI transformation (AX), as a core pillar of deep transformation. Through this, GS Caltex's goal is to switch to a more evolved way of working.
Digital & AI transformation (DAX) is the concept that digital and AI develop complementarily. By applying AI to data and systems accumulated on a digital basis and combining AI suggestions with human judgment, decision-making speed can be increased. It can also strengthen collaboration between humans and AI so that AI serves as a virtual colleague to support tasks such as data collection and analysis and report writing, allowing more focus on creative problem solving and strategic judgment.
◇ AI used to secure safety at business sites
GS Caltex introduced AI-based CCTV at its Yeosu plant to detect potential hazards within the business site in real time. For high-risk tasks such as working at heights and in confined spaces, it uses drones and robots to improve work safety and inspection efficiency. It has also built experiential safety training centers based on virtual reality (VR·Virtual Reality) and mixed reality (MR·Mixed Reality). Employees can virtually experience work procedures and safety accidents in advance, which strengthens safety awareness and helps prevent accidents. In addition, it introduced an AI-based vibration analysis system to continuously analyze vibrations of rotating machinery at business sites and detect equipment abnormalities early.
GS Caltex developed "AnGenbot," a generative AI-based safety regulation chatbot. AnGenbot helps workers quickly and easily check the safety information they need so they can focus on their tasks. AnGenbot also provides fast and accurate answers to questions about safety regulations based on the company's internal safety manuals. Furthermore, it has a function to identify potential hazards when a site photo is uploaded, giving it the ability to detect risks in advance.
GS Caltex has strengthened safety management by introducing digital technologies such as AI-based CCTV and drones not only at the Yeosu plant but also at the Incheon logistics center. In recognition of these AI-based industrial safety enhancement efforts, GS Caltex's Incheon logistics center won the grand prize (Minister of Employment and Labor Award) at the 2025 AI·Smart Industrial Safety Technology Best Practices Competition hosted by the Ministry of Employment and Labor.
◇ AI-based production process optimization
GS Caltex is also using AI models it developed in-house to optimize production processes based on vast amounts of data generated at the Yeosu plant. Previously, when a process anomaly occurred, responses relied on workers' skills and experience, but AI models can now detect early signs of process abnormalities and derive problem-solving measures in real time.
The AI models also analyze process data collected in real time to predict the specifications of each product and, based on that, determine optimal operating conditions, contributing to increased production of high-value-added products. AI-based process optimization is expected to be an important opportunity to improve profitability through reduced production expenses and improved operational efficiency.
◇ introduction of in-house generative AI integrated platform "AIU"
GS Caltex introduced an in-house generative AI integrated platform called "AIU" in the first half of this year to create an environment where employees can use generative AI safely and conveniently in their work. AIU is a word combining AI and 油 (oil), symbolically reflecting a strategic direction to strengthen competitiveness by applying AI technology to the traditional refining industry. AIU was developed based on MISO, GS Group's common AX (AI Transformation) platform. Employees can apply various generative AI tools to real work without uploading company data and expertise to external generative AI services.
In particular, AIU is designed so employees can easily create AI agents (intelligent digital assistants that can make judgments and act on their own without human instructions) by combining generative AI technology with the company's internal data. AIU supports intuitive development tools so that even those without digital technology expertise can develop AI agents with minimal coding. GS Caltex employees now have an environment where they can implement an app that previously took a professional developer a month to create within a week.
◇ operating a "digital academy" to cultivate digital talent
Since 2023, GS Caltex has operated a "Digital Academy" so that digital & AI transformation (DAX) does not remain the domain of a few experts but leads to the internalization of digital capabilities among actual employees. It raises employees' understanding of digital technology and generative AI and supports applying them to real work.
Through the Digital Academy, GS Caltex plans to expand in-house digital experts—such as operational data analysts who analyze practical data and develop machine learning-based optimization models and operational developers who develop apps using low-code methods—to about 10% of all employees by 2025.
GS Caltex also runs "Tech exchange meetings," inviting external experts to share the latest digital technology trends and practical application cases to raise employees' understanding of digital technology and strengthen collaboration and networking across all employees.
A GS Caltex official said, "We will actively introduce generative AI technology across our operations to accelerate AI-based digital transformation and continuously build an environment where employees can focus more on creative and high-value-added work."
