Not out yet. Google hasn't released Gemini Hydrogen, and no release date is confirmed. What we know so far: rumored, not announced; Nov 9 18:15 UTC: @lyraxana says a Gemini 4 Hydrogen (gemini-4-hydrogen) private early-access program has started and that release is expected soon; one account, no screenshot, and Google has said nothing; since Oct 27 accounts on X have called Hydrogen the codename of Gemini 4 Flash (see that entry); all unconfirmed; no hydrogen id on OpenRouter at 18:50 UTC; this hunt fires on any gemini id containing hydrogen. Swept every 60 seconds across provider catalogs. The moment it answers on a public API, alerts fire: a text or a call on paid plans the second it's confirmed, then a free Chrome push and email about 15 minutes later.
