Meta 发布 Brain2Qwerty v2 非侵入脑机解码达 61% 词准确率
AI 推荐理由
与 v1 相比，v2 实现了句子级解码且性能显著提升，开源代码有助于复现和推进脑机接口研究。核心解读
Meta 发布 Brain2Qwerty v2，从非侵入式脑信号实时解码自然句子，词准确率 61%，远超此前非侵入方法的 8%。系统基于 MEG 记录，训练数据来自 9 名志愿者各 10 小时的打字数据（约 22000 句），最佳参与者达 78%，超半数句子解码误差不超过 1 词。Meta 开源训练代码，BCBL 发布 v1 数据集。

Meta says Brain2Qwerty v2 can decode natural sentences from non-invasive brain recordings in real time, reaching 61% word accuracy.
The system was trained on about 22,000 sentences from 9 volunteers, each recorded for 10 hours with MEG while typing.
Meta compares that with 8% word accuracy from prior non-invasive methods. Its best participant reached 78%, with more than half of sentences decoded with one word error or less.
This is still controlled lab research: small participant pool, MEG hardware, active typing data, and company-reported results. Not a clinical communication device yet.
Meta is releasing the training code, while BCBL is releasing the v1 dataset, pushing brain-to-text research further into open neuroscience infrastructure.
I am so hyped for the future.

> We’re sharing the next major milestone in our non-invasive brain-to-text decoder research: Brain2Qwerty v2.
> Building on v1, which was published today in @Nature, Brain2Qwerty v2 is the highest-performing end-to-end pipeline capable of real-time sentence decoding from raw brain signals. It advances beyond character-level performance to decoding words and semantics, enabling accuracy for overall communication.
> We believe this research has the potential to make a real difference for the millions of people who suffer from brain lesions or disorders that prevent them from communicating.
