I could not find a good definition of generative AI from previous postings so here is one generated by Grok (Musk's AI):
Generative AI (often shortened to GenAI) is a category of artificial intelligence that can create new content from scratch — things that didn’t exist before.
It learns patterns from huge amounts of data (text, images, audio, video, code, 3D models, etc.) and then generates new examples that look and feel similar to the training data.
Hope this helps.
