What are you building? What are you solving with LLMs? How do you run them? How do you integrate them in your app / service?
Historically I have worked in NLP, and LLMs have made many older techniques obsolete, and that has been fun.
I have also been using OpenAI APIs for about 2 years and now I also experiment with Anthropic’s Claude 2 and Google Bard. Nothing important, I just want to have a solid intuition on what different commercial models can do.
