ChatGPT app free tier gets GPT-6 Luna

GPT-6 Luna is free now. Gemini 3.5 Flash-Lite is what’s left for free users. The difference shows up in checklists, flashcards, quizzes — and whether you have to leave the chat to make them work.

ChatGPT 6 is now free on Android and iOS — and it’s building interactive tools inside the chat that Gemini no longer matches for most everyday tasks. OpenAI rolled out GPT-6 Luna to all free users on October 8. Google responded the next day by downgrading its free tier to Gemini 3.5 Flash-Lite, pushing users toward paid plans for anything more advanced.

The shift isn’t about raw reasoning power. It’s about what happens after the answer: whether you get a static block of text, or something you can tap, check, flip, score, and reset. All without leaving the app. And right now, ChatGPT 6 wins that race decisively for routine, practical use cases.

Not every one. But five clear ones stood out in side-by-side testing reported by Android Police. Planning your Friday? ChatGPT built a live checklist with a counter (“0 of 13 complete”) and a reset button.

Gemini gave plain text with “[ ]” brackets, untappable. A Spanish flashcard drill? ChatGPT delivered tappable cards with reveal-and-mark functionality. Gemini tried to launch a web app.

Then failed at sign-in and dumped you back into chat. A packing list for Chicago? ChatGPT grouped items by category, added section counters and an progress bar. Gemini listed everything in one column, prefixed with category names, functional, but harder to scan mid-packing.

A cereal value-per-ounce ranking? ChatGPT showed color-coded bars and a ranked visual hierarchy. Gemini’s chart used near-identical white bars. Forcing you to parse numbers manually.

Even the quiz test was lopsided: ChatGPT served up five multiple-choice questions one at a time, with instant feedback, explanations, and a final score screen. Gemini output raw HTML code, no explanation, no execution path. None of this means Gemini is obsolete. It still integrates tightly with Gmail and Docs.

It builds working Sheets files for habit tracking. And it handles scheduled news briefs better than ChatGPT does. But for the kinds of quick, self-contained, interactive micro-tools people build daily. Planners, quizzes, flashcards, checklists, the free tier of ChatGPT now delivers what Gemini’s free tier no longer does.

That gap matters. Especially as search traffic shows people still typing “chatgpt app”, “chatgpt free”, and “chatgpt work”. Not “gemini google”. The change went live globally on October 8.

No regional pricing or rollout delays were cited. GPT-6 Sol remains exclusive to paid subscribers. But Luna, the free version. Is already live, and it’s redefining what ‘free AI’ means on mobile.
