Improving LLM Prompting in Elixir with a Custom Sigil

The author, Charlie Holtz, discusses the creation of a new Elixir sigil ~LLM for better AI prompting, alongside a hex package called :ai that provides AI helpers, aimed at enhancing the experience of using OpenAI's GPT models in Elixir projects. The typical syntax for using the OpenAI client can be verbose and Holtz proposes the use of custom sigils to streamline the process by easily converting strings into the required map format, thus making the code more readable, maintainable, and aesthetically pleasing. Implementation details for the ~LLM sigil, created with the help of GPT itself, and a simple helper function to parse return values and handle errors, are shared. The blog post includes instructions for incorporating the :ai package into Elixir apps and provides examples demonstrating the usability improvements.
