petetheposter · reddit · 2026-07-07

Meta unveiled Brain2Qwerty v2, a non-invasive brain-to-text pipeline trained on roughly 22,000 sentences typed by 9 subjects under MEG. It achieved an overall word accuracy of 61%, with the best subject reaching 78%. Meta simultaneously open-sourced the training code for v1 and v2, and BCBL released the v1 dataset. The significance lies in the fact that non-invasive BCI has long lagged behind invasive solutions; if these results hold, it represents substantial progress. Furthermore, open-sourcing the code and data ensures its value extends beyond a mere headline or benchmark screenshot.
