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.
