Available online as in, you just log in to a website and use it, not on hugging face or github, where you need to download, install and configure.
LLMs are already made so “safe” that they won’t even describe an erotic or crime story - content you would easily find visually represented in all its detail on Netflix, Amazon, HBO, youtube, etc. Ie writing “Game of Thrones” with an AI is not possible in most chat bots anymore.
I don’t know which one of them is good, but I’ve seen like a dozen or so online services, mostly for roleplay / virtual girl/boyfriend stuff etc. They’re paid, though. Or you can pay openrouter (more general LLM connector, also paid). I’m not sure if you’re looking for something like that or something free. They’re definitely out there and available to the public.
It’s mostly OpenAI, Microsoft etc who have free services, but they’re limited in what they’ll talk about. And there is one free community project I’m aware of: that would be AI Horde. It’s mostly for images but offers text, too. I haven’t used it in a while, not sure how/if it works.
AI Horde does both text and image yes. You can easily use it on the browser from https://artbot.site/ (images) or https://lite.koboldai.net/ (text). You can register an account for free on https://aihorde.net/register to go faster than anons (or it’s going to be quite slow). It’s crowdsourced and volunteer run.
