📌 TOPINDIATOURS Update ai: The Most Popular Streamer on Twitch Is Now an AI Constr

Amidst mostly unfounded fears that artificial intelligence is coming for our jobs, it turns out there’s one gig AI is pretty excellent at: streaming on Twitch.

Meet Neuro-sama, a cutesy AI-powered character which is now the top streamer on Twitch by active subscriber-count, according to Twitch Tracker. At the time of writing, Nuero-sama — streaming via the Twitch channel Vedal987 — has 165,268 paid active subscribers, well above the second-highest channel, the human-ran Jynxzi.

On Twitch, each paid subscriber is valued at $5 a month, some of which is split with Twitch. According to an estimate by Dextero, that means Neuro-sama is raking in at least $400,000 a month just from subscriptions — and that’s on top of random viewer donations, sponsorships, and ad revenue.

Over the past few years, content creators known as VTubers have taken Twitch by storm. VTubers are essentially like regular streamers, except they use digital motion-capture effects to alter their voice and appearance, often taking on cartoon-like personas to stand out and appeal to viewers looking for something beyond the physical realm.

Neuro-sama takes the concept one step beyond. Despite appearances, the avatar isn’t merely puppeted by a human streamer, but is entirely AI-generated. The channel’s owner, identified only by the handle Vedal, has been running the channel as his full-time job since at least 2023, according to Bloomberg.

Per the publication’s reporting, the avatar’s speech is first generated by a large language model (LLM) before being converted to audio via another text-to-speech AI application.

Though the AI avatar was originally designed to live-stream the rhythm game Osu, it has since developed a life of its own, discussing random topics with various subscribers who communicate with the LLM via Twitch’s baked-in live chat features.

“Part of it is definitely the novelty,” Vedal told Bloomberg of the character’s popularity at the time. “Part of it is some of the things she says. She can be quite chaotic, saying things humans wouldn’t really say.”

Though Neuro-sama sits atop the Twitch throne at the moment, there is still a ways to go if the channel is ever to become the all-time subscription record holder: it sits at number eight on that list — still an accomplishment that was once unthinkable.

📌 TOPINDIATOURS Hot ai: Chaotic quantum spins organize themselves to emit long-liv

Quantum particles can work together to produce powerful signals. However, those signals are unstable and usually vanish almost instantly.

For decades, one striking example of this problem has been superradiance—a collective effect where many quantum particles emit energy together, producing an intense burst of radiation that rapidly dies out. 

Now, researchers have shown that this long-standing weakness can be turned into a strength. In a new study, scientists demonstrate that superradiance can sustain itself, producing long-lived, highly coherent microwave signals without any external driving. 

“This discovery changes how we think about the quantum world. We’ve shown that the very interactions once thought to disrupt quantum behavior can instead be harnessed to create it. That shift opens entirely new directions for quantum technologies,” Kae Nemoto, one of the study authors and Center Director of the Okinawa Institute of Science and Technology in Japan, said. 

Using a diamond crystal for superradiance

Superradiance occurs when many quantum particles, such as atomic spins, act in unison. Instead of emitting energy independently, they synchronize and release it together, creating a signal much stronger than the sum of its parts. 

The problem is that this process usually burns through energy extremely fast, making it impractical for real technologies like clocks or communication devices. To explore whether this limitation could be overcome, researchers from TU Wien and OIST built a carefully designed quantum system. 

They used a diamond crystal filled with a dense ensemble of nitrogen-vacancy (NV) centers—tiny defects in the diamond lattice where a nitrogen atom sits next to a missing carbon atom. Each NV center hosts an electron spin, which behaves like a tiny magnet that can switch between quantum states. 

The researchers placed this diamond inside a microwave cavity, a structure that traps microwave radiation and allows it to interact strongly with the spins. When the spins were initially excited, the researchers observed a familiar phenomenon: a powerful superradiant burst of microwave emission. 

Then something unexpected happened

Instead of fading away, the system began producing a series of narrow, long-lived microwave pulses. These signals appeared without any external pumping or continuous energy input. 

“After an initial fast superradiant burst, we observe a train of subsequent emission pulses followed by quasi-continuous masing for up to one millisecond,” the study authors note. 

To understand why this happened, the researchers turned to large-scale computer simulations. The calculations revealed that spin–spin interactions inside the diamond were dynamically repopulating the energy levels of the system. 

In simple words, the spins were constantly reshuffling energy among themselves, triggering new emissions again and again. This process, known as self-induced superradiant masing, means the system effectively drives itself. 

The same interactions that usually introduce noise and destroy coherence were instead organizing the spins, creating an extremely stable and coherent microwave signal. “The system organizes itself, producing an extremely coherent microwave signal from the very disorder that usually destroys it,” Wenzel Kersten, lead researcher, said.

The significance of stable quantum signals

Stable, self-sustained microwave signals are essential for technologies such as atomic clocks, navigation systems, radar, and communication networks. 

Plus, “the principles we observe here could also enhance quantum sensors capable of detecting minute changes in magnetic or electric fields. Such advances could benefit medical imaging, materials science, and environmental monitoring,” Jörg Schmiedmayer, one of the study authors and an expert in quantum technology at TU Wien, said.

At a deeper level, the work changes how physicists think about quantum interactions. Instead of viewing complex spin interactions as a source of unavoidable noise, this study shows they can be engineered as a resource. 

Further research will focus on exploring how universal this effect is, whether it can be realized in other quantum platforms, and how precisely the emitted microwaves can be tuned and controlled.

The study is published in the journal Nature Physics.
