My company has internally hosted AI. I use the web interface to copy/past info between it and my IDE. So far I have gotten best results from uploading the official Python documentation and the documentation for the framework I am using. I then specify my requirements, review the output, and either use the code or request a new revision with information on what I want it to correct. I generally focus on requesting smaller focused bits of code. Though that may be for my benefit so I can make sure I understand what everything is doing.
