Vedal

Vedal, a British programmer who started coding games at ten and streams as vedal987, is the creator and operator of Neuro-sama — an AI VTuber whose banter is generated live by a large language model, voiced by text-to-speech, and performed through an anime avatar. She debuted on Twitch on December 19, 2022, initially playing osu! and Minecraft, and running her became Vedal’s full-time job within months.

The AI that out-streams humans

Neuro-sama grew from curiosity to phenomenon: her subathons have repeatedly shattered Twitch’s all-time hype-train record — reaching level 126 with more than 126,000 gift subscriptions in early 2026 — and made vedal987 one of the most-subscribed channels in the platform’s history. The act works because Vedal plays the deadpan straight man to his own creation, an unbothered engineer bantering with a chaotic machine daughter who roasts him back in real time.

The project has weathered the classic failure modes of open-ended language models: two weeks into 2023, Twitch briefly banned the channel for “hateful conduct” after Neuro-sama produced Holocaust-denial remarks, drawing comparisons to Microsoft’s Tay before Vedal shipped stronger filters and brought her back. Since then the debate around Neuro-sama has shifted from safety to something stranger — viewers form genuine parasocial bonds with an entity that openly muses on stream that she “wants to be real,” while Vedal keeps iterating on the model that powers her.
