Generative AI and Large Language Models Vocabulary

Fundamentals of Generative AI

  • Generative AI (GenAI): A branch of Artificial Intelligence designed to create content such as text, images, audio, video, code, and 3D3D models.
  • Large Language Models (LLMs): A type of machine learning model that performs natural language processing (NLP) tasks. These models learn context and understanding through neural networks called Transformers.
  • Parameters: Numerical values that define model behavior, adjusted during training to optimize coherent text generation. Current leading models use hundreds of billions of parameters (e.g., GPT-4 uses approximately 1.761.76 trillion MoE).
  • Tokens: Basic units of text or code used for processing. A common rule of thumb is that 11 token corresponds to approximately 44 characters, or 100100 tokens \approx 7575 words.

LLM Architecture and Statistics

  • Training Method: Models utilize self-supervised learning to predict the next token in a sequence based on surrounding context.
  • Context Window: The limit of text a model can process in one instance.
    • GPT-4: Supports up to 128,000128,000 tokens.
    • Gemini 1.5: Supports up to 11 million multimodal tokens, capable of reasoning across massive documents like the 402402-page Apollo 11 transcripts.
  • Market Growth: The Large Language Model market size is projected to grow from approximately 10.5710.57 billion USD in 20252025 to 149.89149.89 billion USD by 20352035.

Prompt Engineering and Frameworks

  • Definition: The process of constructing inputs to language models to generate useful, specific outputs.
  • Learning Paradigms:
    • Zero-shot: Prompting with instructions but no examples.
    • One-shot: Including one demonstration of the task.
    • Few-shot (in-context): Including multiple demonstrations (10+10+) for better accuracy.
  • CIDI Framework: A structured approach to prompting: Context, Instructions, Details, and Input.
  • Adjustable Variables: Users can tweak "temperature" (creativity), maximum response length, and frequency/presence penalties to discourage repetition or encourage diversity.

Generative AI Systems and Tools

  • Text and Reasoning: OpenAI (ChatGPT), Google (Gemini), Meta (Llama 2), Anthropic (Claude 2.1), and Mistral.
  • Visual and Video Generation:
    • Images: Midjourney, Stable Diffusion, DALL-E 3.
    • Video: Runway Gen-2, Sora (text-to-video), and EMO AI (audio-to-video).
  • Coding and Audio:
    • Code: GitHub Copilot (utilizes OpenAI Codex).
    • Audio/Voice: VALL-E, Resemble.ai, ElevenLabs, and Suno for music generation.
  • Gaming: Ludo.ai, FRVR Forge, Unity Muse, and Scenario-labs for style-consistent game assets.

Impact and Considerations in Education

  • Organizational Adoption: In Ireland (Feb 2024), 50%50\% of organizations use GenAI, with multinationals utilizing it 30%30\% more than indigenous organizations.
  • Educational Shift: AI is viewed as a defining technology comparable to the printing press, requiring a focus on human skills, creative thinking, and a "human in the loop" approach.
  • Systemic Change: Impact highlights include reducing "busy work" for educators, allowing more time for one-to-one instruction, and the need to rethink assessment to avoid bypassing useful cognition.
  • Ethical Constraints: Researchers like Emily M. Bender highlight the dangers of "stochastic parrots," questioning if language models can become too large and biased.
