[Read More]Implementation Notes on LLMs for the Enterprise Use-Case
Note: My blog posts are (still) 100% handwritten, without any contribution from an AI model.
Large language models (LLMs) are very powerful, as ChatGPT has demonstrated very successfully. In this post, I will document some caveats, tips and pointers if you are interested in utilizing an LLM for an enterprise use-case.

This is a tutorial-style article. I wrote it in June/July 2022, but found time to clean up and make a blog post only in September 2022.
This tutorial is relevant to software engineers and data scientists who work with Apache Beam on top of Apache Flink.
Our goal is to set up a local Beam and Flink environment that can run cross-language Beam pipelines.
Specifically, in this tutorial, I will discuss how to set up your laptop to run a Beam pipeline that:
