Meta's Brain2Qwerty v2 Narrows the Gap Between Non-Invasive Brain Decoding and Surgical Implants — Meta released Brain2Qwerty v2, an end-to-end pipeline that decodes typed sentences from non-invasive MEG recordings—no implant required. It reaches 61% word accuracy (up from ~8% for prior non-invasive methods) and 78% for the best participant. The model was trained on ~22,000 sentences from nine volunteers and fine-tunes LLMs on the neural data for semantic context. Meta reports accuracy scaling log-linearly with data volume, framing data scale as the path to closing the gap with surgical approaches. It's open-sourcing training code for v1 and v2; partner BCBL is releasing the v1 dataset. META ↗

My takeaway: Accuracy was the reason to accept a surgical implants in the first place. Meta reports that MEG now narrows that gap between non-invasive and surgical methods, which would let people who need a BCI avoid the surgical risk. The training code is also open-sourced, which can build a community and attract many participants who can help improve it further.

Policy & Society

China moves to regulate AI companion apps — Chinese regulators are drafting rules targeting AI companion apps, which simulate ongoing personal relationships through persistent memory and consistent persona, reflecting broader concerns about the risks of generative AI. AINEWS ↗

My takeaway: I recently saw an article about people forming deep bonds with AI chatbots (sharing everything about their personal lives and trusting the AI's advice completely) who reportedly ended up making tragic decisions. AI is clearly capable, but capability isn't reliability. A smart-sounding answer isn't always a trustworthy one. Along these lines, China's move to regulate AI companion apps is, in my opinion, the right call.
