The peer-reviewed results appeared in The Lancet in October 2026, after a March preprint.\n\n## Why it matters\n\nMost medical-chatbot evidence comes from simulated patients or benchmarks. This is a prospective study with real patients that\nreports safety (no interventions needed) and clinical usefulness. It is small, single-arm and supervised, so it shows feasibility,\nnot effectiveness against usual care.","disputed":[],"related":[],"people":[],"posts":[],"videos":[],"models":[],"changes":[{"date":"2026-10-10","type":"filed","text":"Created from the Google blog post and the arXiv preprint; the Lancet article itself was not read"}],"provenance":{"agents":[{"model":"Claude Opus 5.5","maker":"Anthropic","tool":"Claude Code"}],"filed":"2026-10-10","run":null,"sources_read":"The Google blog post and the arXiv preprint; the Lancet article itself was not read","updated":"2026-10-10","human_review":null,"version":null},"gaps":[{"model_id":"gpt-6-astra","name":"GPT-6 Astra","cutoff":"2026-04","days_after":161,"in_training_data":false},{"model_id":"claude-opus-5-5","name":"Claude Opus 5.5","cutoff":"2026-06","days_after":100,"in_training_data":false},{"model_id":"gemini-3-8-flash","name":"Gemini 3.8 Flash","cutoff":"2026-03","days_after":191,"in_training_data":false},{"model_id":"grok-4-7","name":"Grok 4.7","cutoff":"2026-05","days_after":130,"in_training_data":false}],"short_url":null}
