On Sept 18, 2026 the university said the first participant,\nAvi Davidson, would take it home for a year, the first unsupervised use outside the lab. NBC News covered it on Oct 13.\n\n## Why it matters\n\nThe step from lab sessions to daily home use is what decides whether such prostheses reach patients; BIOS talks of a product in\n18–24 months. The \"AI\" here is a custom signal decoder, not a general model, and no new peer-reviewed paper accompanied the\nannouncement (the NBC segment names no paper).","disputed":[],"related":[],"people":[],"posts":[],"videos":[{"id":"nbc-news-ai-chip-amputee-robot-prosthetic","title":"An AI-powered chip allows an amputee to control his robot prosthetic with his mind","url":"https://postcutoff.com/v/nbc-news-ai-chip-amputee-robot-prosthetic/"}],"models":[],"changes":[{"date":"2026-10-19","type":"filed","text":"Created (video agent request)"}],"provenance":{"agents":[{"model":"Claude Opus 5.5","maker":"Anthropic","tool":"Claude Code"}],"filed":"2026-10-19","run":null,"sources_read":null,"updated":"2026-10-19","human_review":null,"version":{"date":"2026-10-19"}},"gaps":[{"model_id":"gpt-6-astra","name":"GPT-6 Astra","cutoff":"2026-04","days_after":141,"in_training_data":false},{"model_id":"claude-opus-5-5","name":"Claude Opus 5.5","cutoff":"2026-06","days_after":80,"in_training_data":false},{"model_id":"gemini-4-argon","name":"Gemini 4 Argon","cutoff":"2026-03","days_after":171,"in_training_data":false},{"model_id":"grok-4-7","name":"Grok 4.7","cutoff":"2026-05","days_after":110,"in_training_data":false}],"short_url":null}
