Meta decodes typing thoughts without brain surgery
Meta just unveiled Brain2Qwerty v2, an end-to-end AI system that decodes sentences in real time from non-invasive MEG brain recordings, along with open-sourcing its full training code. By processing raw neural data with deep learning and fine-tuned LLMs, it achieved a 61% word accuracy rate—nearing surgical implants. Why it matters: Scalable non-invasive BCIs could restore communication for millions with speech impairments without risky brain surgery.
