Sabi has raised a $50M seed round to build a baseball cap that turns brain signals into prompts for AI models.
That cap can hold up to 100,000 sensors of 1 to 5 millimeters each, feeding a brain foundation model trained on 100,000 hours of labeled neural recordings and Sabi says this cap can predict your next 3-4 keystrokes from brain signals, before you type them.
Sabi designed its own EEG chip, and TSMC fabricated it as the first chip purpose-built for consumer brain-computer interfaces.
Vinod Khosla led the round with Accel, DST Global, Initialized Capital and former OpenAI product chief Kevin Weil, at a reported $600M valuation.
