Exploring langchain4j with Spring Boot: A Practical Journey

Johannes Neubauer Leave a comment

Many examples, tutorials, and blog posts convey the impression that Python is the only language to do AI. This blog post shows that for enterprise applications, Kotlin with Spring Boot is a very good choice in order to build robust AI and Agentic AI applications.

In today’s fast‑evolving landscape of AI‑driven applications, integrating language models into enterprise solutions is essential. This post explores LangChain4j within a Spring Boot environment using Kotlin. I will demonstrate how to declare AI services using annotations, integrate system prompts, dynamic user prompts, and tools — all via declarative interfaces.

The ChatGPT Programming Experience: A Second Attempt

Johannes Neubauer Leave a comment

Welcome back to my series on using ChatGPT for programming (written with help of ChatGPT)! In this second installment, I’ll share my experiences using ChatGPT to build a small software project.

Here you can find the chats: https://github.com/juangamnik/chatgpt-schedule/tree/main/chatgpt

I set out with the premise that I would not write more than a few lines of code, leaving most of the work to ChatGPT. Let’s dive into the numbers, the areas where ChatGPT slowed me down, and the moments where it truly shined.

Large Language Models, GPT, and I

Johannes Neubauer Leave a comment

This is the first blog post in a row that describes my first experiences with ChatGPT as a pair programmer and assistant for a developer. As you will see, these experiences had some ups and some downs, but all in all – spoiler alert – on the one hand is the advancement in A[G]I (Artificial [General] Intelligence) especially in regard of NLP (Natural Language Processing) using LLM (Large Language Models) and GPT (Generative Pre-trained Transformers) very impressive. On the other hand I had to revise some of the observations (and criticism) I made, just weeks later, since the pace of evolution in the AI scene is so freaking high.

So these are the blog posts of this series:

  1. This post
  2. The ChatGPT Programming Experience: A Second Attempt
  3. The Evolution of Large Language Models in Programming: A Broader Perspective

But let’s start at the beginning (the following text has been created with help of GPT-4)…
