Large Language Models (LLMs)
Purpose: Serve as the brain of AI chatbots by generating human-like text based on input data.
Key Characteristics:
- Pre-trained on massive corpora of text data from diverse sources (books, websites, forums).
- Use transformer architecture, enabling parallel processing and deep contextual understanding.
- Fine-tunable for specific domains or tasks.
Popular LLMs:
- OpenAI's GPT series (e.g., GPT-3, GPT-4)
- Google's PaLM and Gemini
- Meta's LLaMA
- Anthropic's Claude
Applications:
- Conversational agents (chatbots, virtual assistants)
- Text summarization
- Code generation
- Content creation and personalization
Benefits:
- High-quality, coherent responses
- Language and task flexibility
- Minimal manual rule-setting
Challenges:
- High computational requirements
- Risk of generating biased or harmful content
- Difficulty ensuring factual accuracy
- Data privacy and usage concerns
