Glossary of Terms

• LLM - Large Language Models
• NLP - Natural Language Processing : Enabling machines to understand, interpret and generate Human (Natural) Language.
• OpenAI -
• GPT - Generative Pretrained Transformer
• ChatGPT - AI-powered conversational chatbot using OpenAI GPT models as LLM
• RAG -

LLMs and their Evolution

• Large Language Model is a type of AI designed to understand, generate, and summarize human-like text by analyzing massive datasets using deep learning, specifically transformer architectures.
• LLMs work by predicting the next word in a sequence based on prompt context, enabling tasks like chatbot interaction, translation, and code generation.
• Populat LLMs
  • GPT models by OpenAI
  • Gemini by Google
  • Claude by Anthropic
  • Llama by Meta
• ChatGPT uses gpt-models of OpenAI behind the scenes

Building Bloacks of LLM and NLP

• Artificial Intelligence : computer systems designed to carry out tasks that normally need human intelligence
• Machine Learning : Focuses on building algorithms that allow the system to learn by itself.
• Deep Learning : Branch of ML focusing on algorithms that lead to Artificial Neural Networks. These excel inprocessing vast amount of data and are highly effective in tasks like image and speech recognition, as well as NLP
• GPT (Generative Pretrained Transformer) : Based on Transformer Architecture, Uses attention mechanism to understand

Evolution

• n-grams
• Neural Language Models (RNNs and LSTM)
• Transformer Architecture
• LLMs (GPTs)

Popular LLM Models

• Properiatary/Closed Source Models :
  • Not available for public download or modification
  • Paid services accessed through API calls
  • Examples
    • OpenAI - GPT
    • Gemini by Google
    • Claude by Anthropic
• Open Source Models :
  • Free available for Public
  • Examples
    • LLaMA by Meta
    • Mistral by MistralAI

Advantages

• Multilingual Capabilities
• Creativity and Content Generation
• Automation of Complex Task
• Rapid Prototyping

Challenges

• Bias and Fairness
• Ethical Concerns - Fake news, Deepfakes
• Lack of Explainability - Industries like Legal, Medical or Financial
