Beebo Brink: there are options which you can get web based only, like Midjourney. Most of them offer a freemium model, meaning you get a few pics for free per day/week/month, after that you've got to pay for it.
Then there's stuff you can get in both versions, like Stable Diffusion. If your GPU is potent enough, it should have at least 8 GB VRAM (best brand is Nvidia, then comes AMD), you might just run it on your own machine. Since Stable Diffusion is also open source, there's tons of additional models and tools around you can use with it.
A new version of the annoying orange.
