# Meta Achieves 61% Accuracy in Non-Invasive Brain-to-Text Decoding

> Meta's research arm has made a striking jump in reading language straight from the brain without surgery. Its Brain2Qwerty v2 system uses a magnetoencephalography scanner, which detects the faint magnetic fields brain activity produces, to reconstruct typed sentences at 61% word accuracy on average, and 78% for the best participant. The model was trained on 22,000 sentences from nine volunteers who typed while wearing the device. For context, earlier non-invasive approaches topped out around 8% accuracy, so this is a large leap for a method that requires no implant. It is still far from clinical use, and the MEG hardware is bulky lab equipment rather than anything wearable, but Meta has open-sourced the work for other researchers. The significance is in the direction of travel. Invasive brain interfaces get the headlines, yet a non-invasive path that keeps improving could eventually matter more for accessibility and communication, reaching people who would never accept surgery. Part of Meta's Digital Brain project, it hints at real-time decoding as a plausible long-term goal.
