Agree 100% with premise of the article. I feel like the big secret of the recent advances in LLM tooling is that these are all just variations of “send a chat request and process the output.” Even Tool Calling is just wrapping one chat request with another hidden one that is asking which of N tools applies and what the parameters should be. RAG is simply pre-loading a bunch of extra text into the chat request, etc.

My main point being, though: for anyone intimidated by the recent tooling advances… you can most definitely do all this yourself.
