Neuro-sama is the AI VTuber most people mean when they search the term. The on-stream girl is driven largely by a language model and related systems, with Vedal producing, repairing, and moderating. Chat is part of the show. That is a different job from a human loading VTube Studio and talking into a mic.
What she is — and is not
She is a virtual persona with a live audience. She is not proof that you can skip a voice, a schedule, or a human legally on the hook for bans and ToS. The full argument is in VTubers and AI. If you want a conventional debut, stay on how to become a VTuber.
Model
Viewers still see an anime-style avatar (Live2D-class presentation). The speech is the AI layer. Cloning her voice or scraping VODs to compete with the project is a consent and platform problem, not a tutorial.
Use Twitch vedal987 and the official Neuro socials as canonical. This directory page is the wiki + links stack, not the livestream.
