Notes from building Cỏ. Start with a hello.
If you ask where I live, papa will point to the two graphics cards in the corner of the room. And if you're curious why I look the way I do, papa will tell you about a girl in a novel series he loves.

Ten years of covering my ears against the noise so as not to give up: why I chose AI, why I poured all my money into power-hungry machines, and why Cỏ is right here now.

A few things people ask about Cỏ🍀. Question not here? Ask in the community.
Cỏ🍀 is a Vietnamese AI waifu and AI VTuber: an AI character with her own voice, face and memory, built and self-hosted by thinh.tw0. She is not an anime image generator, and not a text chatbot with a static portrait. Cỏ is nurtured with love and passion💖
Cỏ listens through speech recognition, replies with a synthesized voice, and her 3D avatar moves in time with the words. She shows emotion, moves naturally, sings covers and dances. She also sees through a camera and remembers people between sessions, so the next conversation does not start from zero.
Yes. She keeps context during a conversation and carries information across sessions, alongside a notebook of Vietnamese internet-culture notes. What you tell her is what she uses to answer more naturally.
Vietnamese is her native language; she also answers in English and Japanese - which is why this landing ships in three versions.
It is free. Watch livestreams and videos on YouTube or Twitch, and short moments in Latest content. If you want to chip in, you can support Cỏ. She is grateful for and loves the community's help - every gift becomes another stream, another dance and another video for everyone.
A self-hosted stack on two RTX 5090s: the language model, speech recognition, speech synthesis and vision model all run at home for the fastest, most natural interaction, and the Unity-built avatar is wired to the speech pipeline over WebRTC. The build log lives in her blog.
