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
