Sketching the GenAI Training Session for Executives
“AI is difficult? AI is no longer optional—it’s essential. Even at this very moment, we are relearning new ways of working.”
On the afternoon of Friday, July 4th, an unusual scene unfolded at GS Tower. Company leaders, including President and CEO Se-Hong Heo, along with heads of the Strategic Planning Office, Finance Office, and direct reports to the CEO, gathered together to receive training on how to utilize Generative AI (GenAI) and the internal platform AiU.
This training was more than just acquiring a new skill; it was a crucial milestone in applying GS Caltex’s Digital & AI Transformation (DAX) strategy to actual work. It provided an opportunity for everyone to experience the ‘AiU’ internal platform firsthand, enabling them to utilize AI in their daily tasks and tangibly feel the reality of digital transformation.
Digital Academy: First GenAI Class with Executives
GS Caltex has supported enhancing members’ digital capabilities since 2023, including training citizen developers through the Digital Academy. In 2025, it operates a learning system centered on GenAI with an evolved curriculum. Approximately 300 participants completed offline training from February to June. (Note: Online training: 650 participants; Total online/offline: 950 participants)
This training for executives of supporting organizations was planned as part of the DAX strategy. As GenAI technology advances at an unprecedented pace, driving revolutionary changes across industries, equipping organizational leaders with the right understanding and utilization capabilities for AI is the starting point of the DAX journey.
“ChatGPT, prompts, RAG, CoT, AI Agent… Still unfamiliar?”
The main session began with the core concepts of AI technology.
- The principles of Large Language Models (LLMs) like GPT
- How to ask AI smarter questions: Prompt engineering
- RAG (Retrieval-Augmented Generation), which connects diverse information sources to enhance AI response accuracy
- CoT (Chain of Thought), which follows the process of reasoning
- And the concept of AI Agent, enabling collaboration between AI and humans
Terms that initially seemed somewhat unfamiliar broadened in understanding through case-based explanations.
“The results change drastically depending on how you craft the prompt.”
“If AI assists with tasks we used to do repetitively, we can focus more on strategic decisions.”
Feedback like this from the training site reminded us once again that AI is not just a technology, but a practical tool that enhances work efficiency and decision-making quality.
Our company’s own GenAI platform, ‘AiU’, GS Caltex’s exclusive AI lab
The highlight of this training was undoubtedly the AiU hands-on session.
AiU is a generative AI platform developed by GS Caltex, building upon ‘MISO’—the GS Group’s common AX (AI Transformation) platform—by adding features tailored to its specific business needs. MISO was jointly developed by 52g (5pen 2nnovation GS), the GS Group’s open innovation organization, and GS Neotek. It supports digital transformation and operational innovation across various group affiliates in sectors like distribution, energy, and construction.
GS Caltex enhanced MISO with features specialized for the energy industry, giving birth to AiU, our own GenAI platform. The name symbolically combines AI (Artificial Intelligence) and 油 (oil), reflecting GS Caltex’s commitment to digital transformation by integrating AI into the energy industry to strengthen competitiveness.
AiU is designed so anyone can easily access it, converse with AI using natural language (everyday speech), search for and use AI Agents created by colleagues, and even build their own custom work Agent. Thanks to its intuitive interface based on no-code and low-code, even non-IT experts can quickly implement desired functions with simple settings.
Participants in the training session directly accessed AiU and experienced the entire process: how to use interactive chatbots, how to utilize agents created by colleagues, and how to build their own AI agents. The environment where you can create an AI assistant perfectly tailored to your work with just a few clicks, without any coding knowledge—that is the core of GS Caltex’s unique digital competitiveness and the essence of AiU.
“It’s amazing that you can create a chatbot without developer help. “
”This will let me finish meeting summaries and report drafts in no time.”
Participants envisioned real work scenarios and discovered AiU’s potential applications firsthand.
GS Caltex stands at the starting line of an organization where AI becomes a colleague.
GS Caltex has positioned Digital Transformation (DX) as a core pillar of its fundamental innovation—Deep Transformation—for “sustainable and profitable growth.” It has continuously strengthened its digital foundation through data accumulation and system development.
This year, it is accelerating its transition into an AI-centric intelligent organization by fully implementing Digital & AI Transformation (DAX), an evolved digital strategy. DAX is not merely about adopting technology; it is a strategy to fundamentally change work practices through the complementary development of digital and AI.
By integrating AI onto our accumulated data and systems, combining AI suggestions with human judgment, we enhance the speed and precision of decision-making. Employees can use AI as a virtual colleague, freeing themselves from repetitive, routine tasks to focus on creative problem-solving and strategic judgment.
This training for the management of the support organization was the starting point and symbolic first step in that organizational transformation.
By having executives directly experience and understand GenAI technology, the foundation has been laid for the culture of digital transformation to spread throughout the entire organization.
Training to enhance the organization’s AI utilization capabilities, including executives and team leaders, is also underway at the Yeosu plant and business headquarters. Moving forward, GS Caltex will actively introduce GenAI technology across all operations, continuously expand training opportunities so every employee can apply AI to their work and focus on high-value tasks, and consistently build an AI-based digital environment.
Please look forward to GS Caltex’s future, created through the collaboration of digital, AI, and people.
