According to The Rundown AI on X, Sabi emerged from stealth with a noninvasive brain–computer interface beanie embedding 70,000 to 100,000 miniature EEG sensors, enabling text input by imagining words, with a first product targeted for late 2026 and a baseball cap variant to follow. As reported by The Rundown AI, Sabi has collected 100,000 hours of brain data from 100 volunteers to train a brain foundation model, positioning the system for generalizable decoding without surgery. According to The Rundown AI, investor Vinod Khosla, an early backer of OpenAI, argues mass-market BCI must be noninvasive to reach billions of users, underscoring consumer-form-factor design as a go-to-market strategy. For AI businesses, the opportunity lies in foundation-model-powered neural decoding, edge inference on wearable EEG arrays, and new input modalities for AI assistants and productivity apps, according to The Rundown AI.
