It's already here. I run AI models via my GPU with training data from various sources for both searching/GPT-like chat and images. You can basically point-and-click and do this with GPT4All which integrates a chat client and let's you just select some popular AI models without knowing how to really do anything or use the CLI. It basically gives you a ChatGPT experience offline using your GPU if it has enough VRAM or CPU if it doesn't for whatever particular model you're using. It doesn't do images I don't think but there are other projects out there that simplify doing it using your own stuff.
