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.

Its discovery adds a new layer of control for OpenAI’s flagship chatbot, though it remains invisible to free‑tier users. Lire la suite

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. Lire la suite
