What is a Large Language Model (LLM)?

A large language model (LLM) is a type of AI that can understand and generate human-like text. It's trained on vast amounts of text data to learn patterns, language structures, and relationships between words and sentences.

How do LLMs work?

LLMs predict one token (like a word or character) at a time, building a sequence from start to finish. They try to predict the next token based on patterns learned during training.

What are parameters in LLMs?

Parameters are variables that LLMs learn during training. They represent the knowledge and understanding gained from the data, like a set of rules and associations.

What makes LLMs 'large'?

LLMs require significant computational resources, like powerful servers and lots of memory, to handle the massive amounts of data they process.

What is the 'generative' aspect of LLMs?

LLMs are 'generative' because they can create new text based on the patterns they've learned. They can write stories, articles, and even translate languages.

Study Notes

Large Language Models (LLMs)

  • LLMs are advanced computer models designed to understand and generate human-like text
  • They are trained on vast amounts of text data to learn patterns, language structures, and relationships between words and sentences
  • LLMs are like digital assistants that have read vast amounts of text (up to 2021) and can answer questions based on that information
  • They don't understand like humans, but they are highly skilled in remembering and connecting information

How LLMs Work

  • LLMs predict one token (word or character) at a time, building a sequence
  • They predict the next token based on patterns observed during training
  • LLMs can generate coherent and relevant text on various topics
  • LLMs use significant computational resources; multiple processors and large memory to process massive amounts of data, enhancing their comprehension and generation capabilities.
  • Parameters are variables that the model learns from data; more parameters mean better ability to learn intricate patterns
  • LLMs trained with billions of parameters are considered large and powerful

LLM Training

  • Training an LLM is like teaching a robot human language
  • It involves gathering a massive corpus of writings (books, articles)
  • The robot practices reading, guessing the next word, and receiving feedback on its guesses
  • The process repeats with numerous sentences
  • The robot eventually learns to predict words more accurately, through tests
  • Specialization is creating a LLM exceptionally good at a particular language, like medical language

Fine-Tuning LLMs

  • Fine-tuning is further training a pre-trained LLM on a new, smaller, and more specific dataset
  • Imagine a robot who has learned to cook many cuisines. Fine-tuning is like teaching the robot a new, more specialized cuisine (like Italian)
  • Fine-tuning utilizes pre-trained knowledge for efficiency while requiring less data.
  • It enhances performance in specific tasks with improved result.

LLM Versions

  • LLM versions improve upon previous versions by incorporating feedback, research, and advancements
  • They often have larger sizes, more parameters, and are trained on larger, more diverse datasets
  • Variations or iterations also exist within these models like BERT, RoBERTa, and DistilBERT.

Salesforce and LLMs

  • Salesforce offers various ways to use different LLMs, including shared and hosted third-party LLMs.
  • Shared LLMs allow access across the internet, connecting to external LLMs via a secure gateway
  • Hosted LLMs are directly integrated into Salesforce’s infrastructure with improved data privacy, security, and compliance.
  • BYOM option allows using pre-trained, individual models, offering greater control.
