First, there is an overwhelming amount of educational materials available. I will share some of them here. For questions and study sessions related to AI, including these materials, the Hugging Face Discord server is almost the perfect platform for that purpose. There are also channels for reading groups and more.
Of course, there are many other Discord servers besides Hugging Face, and many people have created their own personal groups. You may also be introduced to or discover other groups through the Hugging Face Discord server.
Additionally, for image generation, Civitai is another large community worth checking out.
