Lecture on Generative AI

General Overview

  • Ever since computers were invented: They have been glorified calculators executing exact instructions given by programmers.
  • Recent Advancement: Computers now have the ability to learn, think, and communicate like humans (Generative AI).
  • Impact: Generative AI can affect every individual and company positively or negatively.
  • Key Product: Products like GPT (Generative Pre-trained Transformer) make intelligence available as a service.

What is Generative AI

  • Analogy: Imagine having Einstein in your basement, representing collective intelligence. You can talk to him, but the main limitation is your imagination and communication skills.
  • Prompt Engineering: The skill of effectively communicating with the AI is essential.

Traditional AI vs Generative AI

  • Traditional AI: Machine learning, computer vision, recommendations, and search results.
  • Generative AI: Generates new, original content instead of just classifying existing content.

Large Language Models (LLMs)

  • Definition: A type of Generative AI that communicates in human language.
  • Chat GPT: A product by OpenAI that started as an LLM using Transformer architecture.

How it Works

  • Neural Networks: Convert words into numbers, process them, and convert numbers back into words.
  • Training: LLMs are trained on large datasets using a process called backpropagation.
  • Reinforcement Learning: Involves human feedback for better and more accurate results.

Types of Generative AI Models

  • Text-to-Text: Generates text (e.g., GPT models).
  • Text-to-Image: Generates images from textual descriptions.
  • Image-to-Image: Transforms or combines images.
  • Image-to-Text: Describes the contents of an image.
  • Speech-to-Text: Voice transcriptions.
  • Text-to-Audio: Generates music or sounds.
  • Text-to-Video: Generates videos.

Applications and Trends

  • Multi-modal AI Products: Combine different models into a single product.
  • Example: Chat GPT mobile app can interact with text, images, audio, etc.
  • Emergent Capabilities: AI can now roleplay, write poetry, code, advise on strategy, among other tasks.

Exponential Growth and Impacts

  • Human Intelligence vs AI: Human intellectual abilities are static, while AI capabilities are growing exponentially.
  • Past Revolutions: Compared to fire, agriculture, printing press, etc., AI evolves much faster.

Mindsets Towards AI

  • Denial: 'AI cannot do my job' – dangerous.
  • Panic: 'AI will take my job' – unhelpful.
  • Balanced Positive Mindset: AI will make you and your company more productive.

Human Roles in the Age of AI

  • Continued Necessity: Human domain knowledge and judgment are still needed.
  • Example Roles: Doctors, developers, lawyers, CEOs, teachers, etc., can use AI as a tool but still need to guide and manage it.

Interaction with AI Models

  • Product vs Model: Users interact with products (apps, websites), not directly with AI models.
  • APIs: Allow developers to integrate models into their products.

Prompt Engineering

  • Example: Planning a workshop – iteratively refine prompts for better results.
  • Importance: Key skill for effective use of AI.

Future Trends

  • Autonomous Agents: AI entities with tools to execute tasks autonomously.
  • Prompt Design: Essential for managing autonomous AI.

Key Takeaways

  • Tool for Productivity: Generative AI can significantly enhance productivity.
  • Imagination and Skills: The main limitations are your imagination and prompt engineering skills.
  • Deliberate Practice: Improve prompt engineering skills through consistent practice.
