As the power and utility of Language Model (LLM) technology continue to grow, so too does the importance of Prompt Engineering - or Prompt Programming - in guiding its application. In this session, we'll provide a quick recap on how LLMs work before diving into the world of Prompt Engineering. We'll examine different types of prompt engineering and weigh the pros and cons of their use. But with great power comes great responsibility, and the risks of "prompt demons" in the form of security concerns with prompt injection cannot be ignored. To address these issues, we'll discuss the best practices for secure prompt engineering, and explore the future of prompt engineering and security with LLMs. Join us for an informative session on navigating the balance between innovation and security with Transformer models.
