I first learned about the KRAFTON AI Fellowship through the MIT MISTI program and previous participants. That experience sparked my interest in KRAFTON as a company, and although I was born and raised in the United States, I’ve always wanted to start my professional career in Korea—so I decided to apply.

At the time of the exam, I hadn’t formally studied artificial intelligence, so I relied mostly on mathematical intuition to solve the problems. When I passed the third interview and received the final acceptance email, I was filled with excitement—but also a bit of anxiety and uncertainty.

The project I joined was related to LLM Agent research, similar to a recently published paper. I learned a lot from working alongside my team lead and fellow interns, who were incredibly knowledgeable and generous with their support. Getting hands-on experience with the latest LLM technologies, tools, and libraries was immensely valuable and will continue to benefit me even after returning to the U.S.

The culture within the department was very horizontal and autonomous. Even though I was the youngest member of the team, I never once felt like “just the intern,” and despite my Korean not being perfect, everyone treated me with equal respect.

The meals exceeded even my YouTube-fueled expectations. Some days, the quality rivaled that of fine dining restaurants, and the creativity of the daily rotating menu made lunch something I looked forward to every day.

Though brief, this experience gave me the confidence and courage to embrace challenges in any environment moving forward.

KRAFTON AI Fellowship was a program that provided the optimal environment for undergraduate students seeking to conduct AI research. It not only gave me the opportunity to lead my own research project, but also allowed me to collaborate with experienced and highly skilled mentors, utilize abundant computing resources (including daily use of up to four A100 GPUs), and enjoy various welfare benefits that enabled me to focus solely on research. Since everything I needed for my work was readily available during the internship, I believe I was able to achieve significant research results in a short period of time.
The biggest takeaway for me during the fellowship was that “good research starts with good questions.” Throughout the research process, I continually reflected on the direction and value of my work, realizing that for research to be truly impactful, the problem at hand and its importance must be clearly defined. At KRAFTON, there is a solid culture of encouraging research, so even as an intern, I had the freedom to explore my ideas without hesitation. In this open environment, I repeatedly proposed my ideas and received feedback, which allowed me to think deeply about my research and grow at a rapid pace.
KRAFTON’s welfare offerings were also top-tier. In addition to the environment dedicated to facilitating research, there were various perks such as delicious lunch and dinner, as well as a nap room. The nap room, in particular, proved extremely useful for taking a short break after long hours of immersion in research, and I used it often right before paper submission deadlines. I could really sense KRAFTON’s commitment to providing the best environment for researchers, and thanks to that, I was able to maintain a high level of concentration.
All in all, the KRAFTON AI Fellowship was an exceptionally attractive experience in that it provided an environment where one could take on academic-level research in a limited timeframe, communicate with experts, and grow quickly. Completing a paper and submitting it to a conference, as well as taking the lead in a new project, gave me a great deal of confidence and motivation. I highly recommend anyone who is seriously interested in research or AI development to apply. My heartfelt gratitude goes out to the KRAFTON Deep Learning Division for offering this wonderful opportunity, and to all the researchers who worked with me and taught me so much.

The Deep Learning Division at Krafton was much more open and horizontal than I had expected, with active communication happening whenever needed. As a lower-year undergraduate with no prior internship experience, I was initially worried about adapting to corporate life, but I was able to adjust very comfortably. The infrastructure and welfare benefits were beyond what I could have imagined for my first company—so much so that I almost felt they were excessive. And one thing I can say for sure is that the food was always amazing, every single day.
The most challenging part of deep learning experiments—resource availability—was never an issue here. The first week was a bit overwhelming, as I attended briefings on various research fields within the division and reached out to those that interested me. From there, two or three senior researchers with master’s or doctoral-level expertise became my mentors, and we engaged in in-depth discussions about research. Throughout the fellowship, my mentors respected my opinions and ideas while also providing sharp questions and constructive feedback. They guided me on the areas I lacked knowledge in and the competencies I needed to develop as a researcher.
Occasionally, we had mentoring sessions and Q&A events with professionals working at multinational corporations. This was particularly helpful for those of us considering studying abroad or pursuing careers overseas. However, no matter how great the research environment is, research itself is inherently challenging. Perhaps because of that, the given time felt even shorter. Although I couldn’t complete a research paper as a final outcome, I am highly satisfied because I believe I have grown in many ways. Leaving this experience behind is bittersweet. Rather than focusing on immediate results, I feel that I have gained the ability to find the research I truly want to pursue and navigate my own path independently.
Additionally, I learned the importance of seeking help and asking questions—something I realized is a crucial skill. Over what felt like both a long and short period, I went through intense trial and error to discover good research topics and conduct experiments, making me think deeply every step of the way. It had been a long time since I had poured so much passion into a single endeavor. Since the fellowship ensured a high degree of autonomy, the amount I learned and the outcomes I produced were directly proportional to how much effort I put in.
Thanks to this program, I feel like I have left a significant footprint in my life. I truly hope to work in an environment like this again in the future. For undergraduate students interested in learning AI research and actively participating in it, I believe this is one of the best opportunities available.

Before starting the program, my biggest concern was the given timeframe. As someone new to research in the field of AI, I wondered how much I could learn and gain in such a short period. However, my time at Krafton proved that my worries were unfounded, as I was able to grow rapidly.
The best part of the experience was the people. Senior researchers in the Deep Learning Division and my fellow interns became excellent mentors throughout my internship, allowing me to learn quickly and actively participate in research. Additionally, I had frequent mentoring opportunities with researchers working overseas, which greatly broadened my perspective.
Another highlight was the unique nature of the Deep Learning Division within a gaming company. The environment was as free and open as a university lab, allowing research on various topics beyond just gaming. At the same time, I had the chance to work on large-scale game AI projects—an experience unique to Krafton.
I can’t leave out the work environment and welfare. I was genuinely surprised at how delicious the company meals were, and even more amazed at how good food and excellent facilities could contribute so much to overall happiness.

Since mid-April, I have joined the Deep Learning Division as a KRAFTON AI Fellow. The reason I applied for the AI Fellowship was that, as someone who had focused on theoretical research, I saw this as a great opportunity to gain experience in applied deep learning research before pursuing graduate studies.
When I first joined the lab, I was surprised by the level of freedom—so much so that I wondered if it was really okay. I believe that a rigid atmosphere hinders creative thinking in research, so I was very satisfied with the open and relaxed company culture. I had many small talks with colleagues, discussing not only specific research topics but also general research-related topics. Inevitably, research comes with challenges, but I was able to openly discuss difficulties and overcome them more smoothly thanks to this environment.
Casual research discussions often led to collaborations. Once, I had a brief conversation with a researcher working on 3D rendering, and I found the problem they were working on to be very intriguing. I immediately asked if I could join their research, and they gladly accepted, leading to a collaborative study. Seeing how easily and naturally collaborations formed made me realize that this was a great place to engage with interesting topics and conduct research directly.
Even with a great research culture, insufficient infrastructure can be a major obstacle. However, KRAFTON’s Deep Learning Division has an incredibly well-equipped infrastructure. I never once had to pause my research due to a lack of resources. With dozens of A100 GPUs readily available, I could freely utilize them for my research! Additionally, many deep learning tasks require tedious setup, such as GPU connections and terminal configurations, but the lab had already anticipated these challenges and provided an easy setup process, allowing me to quickly adapt to the coding environment and dive into research.
I believe the Deep Learning Division is an ideal place for self-motivated individuals. It goes without saying that nothing happens if you remain passive. When I had something I wanted to work on, I felt confident that there was no better place than KRAFTON’s Deep Learning Division in terms of both human and material resources.
