A.I. Summit
We’ll unpack how foundational concepts like large language models, vector search, and knowledge augmentation are being applied in strategic contexts across industries. More importantly, we’ll address what true readiness looks like—organizationally, technically, and culturally. Through real-world examples and a pragmatic lens, you’ll be invited to assess both your company’s AI maturity and your own role in guiding its evolution.
If you’re navigating transformation or simply asking “what now?”, this session is designed to inform, challenge, and engage—not to sell, but to spark a more meaningful conversation.
Executive Learning Opportunity:
This discussion also introduces our executive-level Generative AI course: a focused 20-hour program built for C-suite leaders. The course provides the frameworks, language, and actionable roadmap needed to lead AI adoption with confidence. By linking strategic insights to hands-on decision-making, it ensures leaders don’t just understand AI—they can act on it.

We’ll begin by experimenting with prompt engineering, where participants will explore different ways to structure inputs to guide AI responses. By adjusting tone, specificity, and constraints, they will see how small modifications can significantly improve relevance, coherence, and accuracy.
Next, we will dive into response optimization techniques, demonstrating how settings like temperature, response length, and system instructions impact AI-generated content. Attendees will practice adjusting these parameters through interactive exercises, gaining intuition on how to tailor AI behavior for different use cases.
Finally, we’ll discuss efficiency and best practices, showing how to make interactions smoother, reduce hallucinations, and achieve more reliable outputs. By the end of this session, participants will have a hands-on understanding of how to effectively work with GenAI models, empowering them to leverage AI assistants like a pro.

We will start with the fundamental principles of Generative AI, explaining how models like Llama and DeepSeek-R1 generate human-like responses. Participants will gain insights into key architectural components, including transformers, attention mechanisms, and tokenization, as well as the differences between training and inference processes.
Moving beyond the basics, we will explore essential optimization techniques used to enhance model performance. This includes strategies for improving response accuracy, reducing latency, and balancing computational efficiency. Attendees will also learn about the latest advancements in fine-tuning methods, parameter-efficient training, and the trade-offs between different deployment strategies.
By the end of this session, participants will have a strong conceptual understanding of Generative AI, equipping them with the knowledge to build and optimize AI applications in the next hands-on session.
