Neuralink's brain-computer interface has ushered in the most powerful upgrade: Grok is connected to the brain, and patients can directly awaken AI with their thoughts. Recently, Musk's brain-computer interface company Neuralink has ushered in a shocking and major technological development - the artificial intelligence model Grok is directly connected to the human brain. This means that the brain-computer interface is moving from a simple "thought-moving cursor" to a new era of "thought-controlled AI". 72 hours of extreme liver damage: Engineers live in patients’ homes to develop 8 major functions. Behind all this comes from a high-intensity practical battle recently launched by the Neuralink team. Several core engineers directly packed their luggage and moved into the subject's home. After 72 hours of high-intensity extreme retreat development, they produced eight brand-new technology prototypes in one go. Subject Kenneth is a Neuralink P21 clinical trial patient who has been diagnosed with ALS for seven years. In the face of illness, he always maintained an extremely optimistic attitude. With the full cooperation of engineers, the technical achievements born in these 72 hours not only opened up the capture of underlying neural signals, but also extended all the way to the deep integration of system-level interaction and top-level AI large models. From bottom-level signals to top-level AI: panoramic analysis of core functions Neural Voice Activity Detection (Neural VAD): In the past, patients who wanted to speak with their thoughts had to manually press the switch button, which was a big burden for patients with high paraplegia or ALS. To this end, the team developed a "Neural Speech Activity Detection" system, which is like a neural sentinel on call 24 hours a day, capable of monitoring the flow of EEG signals returned by the implant in real time. The system can automatically distinguish whether the patient is in a resting state or is about to speak, and automatically starts decoding at the millisecond level after capturing the intended pulse, and automatically goes to sleep as soon as the voice falls, realizing a true "open mouth" with zero button presses and pure thoughts. Real-time neural signal visualization: In response to the black box problem of "what thoughts in the mind can trigger the strongest discharge", the team made a real-time picture of the signal intensity and spatial distribution detected by the implant and fed it back to the patient. This creates closed-loop neurofeedback, allowing patients to back-train and adapt the decoder through intuitive, real-time visual breakthroughs. Linkage between mobile phone brain-computer input method and lock screen: The team further installed the speech brain-computer decoding system into the mobile phone and completed a barrier-free ordering test in a real cafe scene. In addition, by calling the underlying interface of Apple iOS and combining the "real-time activity" and smart island mechanisms, a system-level brain-computer input method and a lock screen resident interface were developed. The patient does not need to unlock the phone, and can pronounce the words in seconds while the screen is locked as soon as the thought occurs. Grok agent communicates with thoughts: The most sci-fi part of this upgrade lies in the brain-computer interface and large-scale model
