Google has quietly locked free Gemini users into automatic model selection — no manual switching allowed. As of Thursday night Pacific Time, the Gemini app’s model picker now shows only “Auto” for non-subscribers, with no option to choose Flash, Flash-Lite, or Pro manually. The change is live for most free accounts globally, per 9to5Google’s testing. It’s not a bug. It’s policy. And it’s tied directly to the rollout of new “effort levels”, a rebranding of the old “Extended thinking” toggle, now aligned with Google AI Studio and Antigravity’s terminology. Free users get Auto. Paid users get control. And soon, fewer choices of their own. Google AI Plus subscribers will soon be restricted to just two models: Flash-Lite and the newly named (3.8) Flash. No Pro. No fallbacks. Just those two. That’s a narrowing, not an expansion. The official line? “Gemini will use auto model selection to send each prompt to the Gemini model that suits it best.” Most prompts go to Flash-Lite, the fastest, lightest model. Only those needing “deeper reasoning” get bumped up to Flash or Pro. But free users won’t know which one ran. Or why. They’ll just see the output. If they turn off smart model selection, everything defaults to Flash-Lite. Every time. No exceptions. This isn’t about performance. It’s about segmentation. Google is drawing a hard line between what free users get and what they control. The “Auto” label hides the logic, but not the limitation. The effort levels themselves. Three tiers replacing Extended, are rolling out to all subscribers now. But for free users, the only level that matters is the one they didn’t pick. The rollout is global. No regional carve-outs. No grace period. And no announcement beyond support docs that briefly called the default “(3.5) Flash-Lite”. A name that’s already vanishing from the UI. What comes next? Google AI Studio’s effort-level API is now live for developers. Antigravity’s integration is syncing. And the next Gemini model update, rumored for late November. Will likely tighten the gates further. Free users won’t get early access. They’ll get Auto. Again.
