how do I get into building AI applications? I want build AI models that are able to do things like: automatically label an image with some context a chatgpt bot but trained on private data and documents (for example company documents so it has all knowledge about company) I also want to explore generative AI, both in language and media (image / video). I am comfortable with programming. What are some frameworks and technologies that I should read upon that the AI industry is currently using? Thanks!
