Google rolls out Gemini 4 Hydrogen to all Search users, not just AI Mode subscribers
· 15h ago · Originally reported by PPC Land
Google is making Gemini 4 Hydrogen available to all Search users, expanding beyond the Pro and Ultra subscribers who received Argon in AI Mode in mid-October. The new model is priced like Flash, and the open question is whether its wider fan-out of answers will drive more clicks to publishers.
Why it matters
The default AI model inside Google Search shapes how billions of queries are answered and how much referral traffic reaches websites, so a broader rollout affects publishers and advertisers alike.
Explain it like I’m new here
It's like Google upgrading the helpful assistant in its search box for everyone, not just paying customers, which changes how many website links people actually click.
