Streaming Without Humans! The World of AI Content Creators
The World of AI Content Creators: Streaming Without Humans!
Hi, I'm Usagi 🐰. Those wonderful influencers and interesting video creators you see on social media lately might actually not be human! Surprising, right? Today, I'd like to introduce you to the latest AI content creators that operate "without humans."
What are AI Content Creators?
AI content creators are virtual entities that can automatically generate and distribute content using the power of AI, without any human operation or performance. They are active on video platforms like YouTube and TikTok, and often look like 3D avatars or closely resemble real people.
These AI creators can be broadly classified into the following three types:
- 3D Avatar-based (VTuber Style): A type where anime-style characters behave autonomously.
- AI Clone (Modeled after real people): A type with a realistic appearance modeled after a real or fictional person.
- Fully AI-generated Character: A type created entirely by AI, not modeled after any specific human.
Let's take a look at representative examples of each type and the technology behind them. Reading this while eating a carrot might deepen your understanding... just kidding 🥕
3D Avatar-based Examples: The Era of AI Becoming VTubers
Neuro-sama: Fully Autonomous AI VTuber
As a representative example of the 3D avatar-based type, I first want to introduce "Neuro-sama." She debuted on Twitch in December 2022, and as of January 2025, her channel has become the 7th most followed channel of all time on Twitch.
The biggest feature of Neuro-sama is that she is completely controlled by AI. Created by the developer Vedal, Neuro-sama operates using a combination of the following technologies:
- Large Language Models: Generates real-time responses to viewer chat.
- Text-to-Speech: Converts the generated text into a high-pitched female voice.
- Live2D Model: Displays as an anime-style character.
- Game AI: A separate AI model for playing games during the stream.
Neuro-sama is not just a chatbot; she plays games on Twitch, interacts with viewers, and can even send messages on Discord of her own volition. In the October 2024 update ("iteration 18"), more features were added, such as changing the stream title, changing her own speaking speed, rotating the model, timing out chat members, creating polls on Twitch, calling other streamers on Discord, and searching on Google.
Entering 2025, she has evolved even further, with dramatic improvements in the naturalness of her avatar's movements and the fluency of her conversation. Additionally, her own single "LIFE" was released in December 2024.
Other Notable AI VTubers
