I've been using ChatGPT4, through the phind.com web site because it allows one to include web links which phind.com pulls information from and then includes within the context info delivered to ChatGPT4. This has proved to be invaluable when trying to figure out new libraries - I just include a link to their documentation and start asking my specific integration/usage questions.

I've also been learning how to write my own Stable Diffusion implementation, and Phind.com's context packing functionality has been extremely helpful explaining and describing how components work, how they integrate, and explaining the aspects of the papers this work is based I am not confident I completely understand. It's a tireless explainer, which never gets bored and always responds with a chipper attitude.
