Large Language Models (LLMs) are powerful AI models, specifically neural networks

Large Language Models (LLMs) are powerful AI models, specifically neural networks, trained on massive datasets of text and codes perform various natural language processing tasks. They excel at understanding and generating human-like text, making them powerful tools for tasks like language translation, text summarization, and even code generation.

Types of Large Language models:  

Large Language Model (LLMs) can be categorized in several ways, including by their architecture, training approach, and specific functionalities.

1.       By Architecture:

                                I.            Encoder-Decoder: These models likeT5, use both encoder to process the input and decoder to generate the output.

                              II.            Causal Decoder: These models, such as the GPT series, generate text one token at a time, based on the preceding tokens.

                            III.            Prefix Decoder: these models, like BERT, use a prefix of the input to predict the next token.

2.       By Training Approach:

                                I.            Pre training: LLMs are initially trained on massive datasets to learn general language patterns and structures.

                              II.            Fine-Tuning: After pre training, models are further trained on specific datasets or tasks to improve their performance on those tasks.

3.       By Functionality:

                                I.            Generic Language Models: These models are trained to predict the next word in a sequence, often used for tasks like information retrieval.

                              II.            Instruction-tuned Language models: These models are trained to respond to specific instructions, enabling them to perform tasks like sentiment analysis, text generation and code generation.

                            III.            Dialogue-tuned Language models: These models are trained for conversational AI and chat bots, focusing on generating appropriate responses in dialogues.

Examples of LLMs:

§  GPT series (open AI): Includes GPT-3, GPT-3.5, GPT-4, known for their powerful text generation and capabilities.

§  BERT (Google): A bidirectional transformer model, widely used for various NLP tasks.

§  Lambda (Google): A large language model designed for conversational AI.

§  Claude (Entropic): A powerful LLM focused on safety and helpfulness.
