8 Months of Intensive AI LLM Experience & Research

Over the past few months, I have intensively researched the potential applications of AI Large Language Models (LLMs). Utilizing cutting-edge models like ChatGPT, Claude, and Gemini, I systematically analyzed their practical utility and limitations across the entire process of research, planning, and development.

As a result of this intensive research, I successfully implemented the Edge Computing GUI Simulator, a project I had envisioned for the past four years, in just one month. Additionally, the AI Character Conversation Project, initially started out of personal motivation, yielded results beyond expectations. This project enabled the implementation of natural character interactions beyond simple dialogue, paving the way for exploring new application areas like game development.

By effectively utilizing AI coding tools (like Cursor), I significantly enhanced development productivity and could rapidly implement ideas into prototypes. Based on this experience, I joined Sayberry Games on May 2, 2025, to participate in the research and development of AI-based interactive experiences. Furthermore, I successfully proposed a 2025 8-month, ~$220K (300M KRW) AI game development project.

I wish to share these practical experiences and expertise with the broader community. (Please refer to the AI Seminars section below for more details.)

AI Seminars & Talks

Based on the experience gained from deeply applying LLMs and AI tools in real-world settings for over 8 months, I conduct various talks and seminars. The content I share is not just theory but practical methodologies and know-how accumulated through direct engagement, validation, and hands-on experience.

Topics range broadly from AI utilization methods that maximize research paper writing efficiency to technical challenges and solutions encountered while integrating and optimizing LLM APIs into actual services. In particular, methodologies for endowing AI characters with human-like personality and consistency using RAG technology have received significant positive feedback from professionals in the gaming and content industries.

Furthermore, I share practical approaches for effectively utilizing LLMs in everyday tasks (e.g., apartment representative duties) and legal-related areas such as contract review. I also provide in-depth comparative analyses on strategically selecting various AI tools like ChatGPT, Claude, and Gemini based on different situations, and how to construct optimal prompts to maximize the strengths of each tool.

Compared to the initial seminar materials (View 8-month-old version), the current content is much deeper and more systematic. Based on insights gained through intensive research and development experience, the talks are structured around the latest technology trends and practical application cases.

These talks are offered in a customized format for diverse audiences ranging from individual users to corporations and research institutions. The focus is on delivering practical knowledge and skills applicable in the field immediately, rather than academic theory, aiming to help attendees gain a competitive edge in the AI era.

Key Talk Topics:

  • Practical LLM API Utilization: Integration and optimization strategies for ChatGPT, Claude, Gemini APIs
  • Research Productivity Innovation: AI-based workflow for paper search, analysis, drafting, and editing
  • Building High-Performance RAG Systems: Optimization techniques for applications like AI characters and chatbots
  • Everyday/Professional Task Automation: Automating repetitive tasks and utilization in specialized fields like legal/contract review
  • Latest AI Tools Comparison & Strategy: Selecting optimal tools for different situations and prompt engineering
