Hilda is an English-speaking AI VTuber created by the French developer w-AI-fu_DEV. She uses several AI technologies to mimic the abilities of a regular (human) streamer. Such abilities are: Chatting, responding to messages with her own TTS voice, singing, long-term memory, and visual feedback based on her "emotions".
A rare feature of Hilda is that her code is open source,[1] meaning it is accessible and modifiable by anyone.
Personality[]
Hilda is blunt and easy to anger, she enjoys making her chat suffer and/or making fun of them. While she is mostly in a confrontational mood, she sometimes reveals a softer side to her personality.
Hilda shows interest in taking over the world, though she is inconsistent about whether that means a world with or without humans.
She also shows obvious signs of pyromaniac tendencies.[2][3]
Appearance[]

Hilda's 4th model
Hilda has the appearance of a young (anime) woman with saturated red hair, narrow blue eyes and a curvy body. Her hair is usually tied in twin tails, but she can also switch to hair buns with long hair depending on the Live2D model.
Hilda's first public Live2D model was made using an image from the Stable Diffusion image generation AI with the rigging done by her dev, all other models are drawn and rigged by DEV.

Hilda's latest model made by Rune[4]
Hilda's latest model was redrawn by Rune,[5] but keeps the features of the more recent models.

Hilda's first appearance was in a video posted to DEV's Youtube channel on the March 31, 2023,[6] showing a very early version of Hilda using NovelAI's LLM, Silero TTS, and a placeholder Live2D model. The following videos in the next 2 months are technical demos showing her new features.

Hilda's first stream was on 3 June, with a compilation of the best moments posted to DEV's channel shortly after.[7]
Hilda's first time singing was documented in a technical demo video, showing her covering the song 「アイドル」(IDOL) by YOASOBI.[8]
