ChatGPT users on iPhone have uncovered a concealed menu that lets them pick between High, Medium, and Instant thinking modes for the AI. The option appears after a long‑press on the blue send arrow and allows paid subscribers to tailor response time and depth on a per‑prompt basis. The feature, which mirrors model‑selection tools in the web interface, is absent from the Android app except for a different long‑press shortcut. Its discovery adds a new layer of control for OpenAI’s flagship chatbot, though it remains invisible to free‑tier users. Leggi di più

Senator Bernie Sanders unveiled legislation that would levy a one‑time 50 percent tax on the stock of the nation’s largest artificial‑intelligence companies, creating a sovereign wealth fund estimated at $7 trillion. The fund would distribute annual dividends of more than $1,000 per American and finance health, education and housing programs. A bipartisan seven‑member Independent Commission for Democratic AI would oversee the fund and hold voting shares to block corporate actions deemed harmful to the public. Tech CEOs have expressed limited support, with OpenAI’s Sam Altman saying he remains far apart from Sanders on public ownership. Leggi di più
