LLM
Large Language Models, a type of AI trained to understand and generate human language, often used in natural language processing tasks.

When to use it
Use a Large Language Model (LLM) when simple keyword matching or rule-based systems are insufficient for understanding or generating human language. LLMs integrate vast amounts of language data to perform complex tasks like sentiment analysis, translation, and conversational agents.
Quick example
In ChatGPT, the application needs to generate coherent and contextually relevant responses to user queries. The LLM is the core of ChatGPT, processing input text and generating output based on its training data. ChatGPT itself is a product built around the LLM, leveraging its capabilities to provide interactive conversational experiences.
user input → LLM → response generation → user output
Ecosystem
LLMs interact with various components in a language processing pipeline, including tokenization, embeddings, and fine-tuning processes.
input text → tokenization → LLM → embeddings → output text
Misconceptions
| Misconception | Rebuttal |
|---|---|
| LLMs understand language like humans | LLMs statistically model language patterns |
| LLMs require no further training | Fine-tuning is often needed for specific tasks |
| All LLMs are open-source | Many LLMs are proprietary and closed-source |
Trade-offs
- Versatility — requires significant computational resources
- Accuracy — depends on the quality of training data
- Scalability — can be costly to deploy at scale
