Language Models (LLMs)

Definition

Language models are AI systems trained to understand and generate human-like text. They are built using vast amounts of text data and learn patterns, context, and meaning.

Examples

• OpenAI’s GPT-4: An advanced generative model.
• Google’s PaLM: Specialized for various tasks, including translation and summarization.
• LLaMA, BLOOM: Open-source alternatives for specific use cases.

Key Characteristics

• Contextual Understanding: LLMs can process large chunks of text and generate meaningful responses.
• Pretraining and Fine-tuning:
  • Pretraining: Learning general language patterns from massive datasets.
  • Fine-tuning: Adapting the model to specific domains like healthcare or legal.

Applications

• Chatbots, summarization, translation, content generation, etc.
