AI Development in Java with LangChain4j and Spring AI

Questions and Answers

What is the main issue with using Large Language Models (LLMs) in business applications?

They are not tailored to specific business needs (correct)

They are too expensive

They are too small to handle large datasets

They are only available in Python

What is the purpose of LangChain4j?

To process tokens in chunks of 4k-128k

To create chatbots based on Semantic Kernel types of agents documentation

To provide swappable LLM support for different tasks (correct)

To create a new LLM every 3 seconds

What is the difference between token count and word count?

Token count is irrelevant in Natural Language Processing

Token count is equal to the word count

Token count is usually 25% greater than the word count (correct)

Token count is usually 25% less than the word count

Study Notes

Unleashing AI in Java

LLMs (Large Language Models) are generic, but businesses are not, and this creates a problem
LangChain4j is based on Andrej Karpathy's LLM OS
Swappable LLM support is essential because different LLMs are good at different tasks

Context Window Management

Context window management involves memory management for 4k-128k tokens
System prompt, history, and relevant information are essential for context window management
Tokens are used to break down text for processing, and the token count is usually 25% greater than the word count

Prompt Templates

Prompt templates allow for creating prompts based on parameterized templates
This is useful when chaining calls and creating reusable prompts

Output Parsers

Output parsers allow getting the output in the required format (JSON, POJO, XML, etc.)
They enable processing of output data in a specific format

Chatbots and Translation

A chatbot can be created using LangChain4j and Spring AI
Translation can be done using the translate method, which takes in text and language as input
The output can be parsed using output parsers to get the translated text in the required format

Retrieval-Augmented Generation

LLMs know two things: content they're trained on and content given as context
Teaching an LLM involves training, fine-tuning, or using pre-trained models

Copilot and Tools

Copilot is a concept of using tools with LLMs to perform specific tasks
Tools can be defined as a set of functions that the LLM can use when helping the user
This approach provides controlled access to resources and databases

Fully-Autonomous Agents

Fully-autonomous agents can be created using Semantic Kernel and LangChain4j
These agents can perform complex tasks and interact with users in a conversational manner
