Gemini免費版降級評測:10/9起只剩Flash-Lite可用 | Gemini Free Tier Review: Flash-Lite Only After Oct 9

🇹🇼 Gemini免費版降級評測:10/9起只剩Flash-Lite可用
Google在2026年10月9日正式調整Gemini訂閱方案,這次Gemini免費版的降級幅度不小:原本能偶爾用到Gemini 3.1 Pro的免費使用者,之後只剩下最輕量的Gemini 3.5 Flash-Lite可用,連中階的Flash模型也一併被拿掉。如果你平常靠免費額度處理比較吃重的任務,這次改版會直接影響你的工作流程。
10月9日起,四個方案分別變成什麼樣子
- 免費版:只剩Gemini 3.5 Flash-Lite,原本的Flash與Pro存取權全部收回。
- AI Plus(US$4.99/月):保留Flash-Lite與Flash,但失去Pro模型的使用權。
- AI Pro(US$19.99/月):三個模型全保留,還額外拿到原本只有Ultra等級(US$99.99~199.99/月)才有的Deep Think深度推理功能。
- AI Ultra:維持原本的最高權限不變。
值得注意的是,AI Plus訂閱戶不是統一在10/9當天被砍,Google會用email通知個別用戶的生效日期,等於是分批、錯開上線——如果你是Plus用戶,看到信前都還能照常使用Pro。
免費用戶的感受最直接
對完全沒付費的使用者來說,這次調整等於把Gemini App變成「單一模型」工具。先前免費帳號還能偶爾用到Pro回答複雜問題、做深度分析,10/9之後這條路被封死,只剩Flash-Lite處理基本的問答、摘要、翻譯這類輕量任務。如果你的日常用法包含程式除錯、長文件推理這種需要更強模型的場景,免費版已經不夠用了。
該不該升級到AI Pro?
這次改版其實是把Pro模型的「甜蜜點」設在US$19.99/月的AI Pro方案——不只保留全部三個模型,Deep Think這個原本要加價到Ultra等級才解鎖的深度推理功能也下放進來,等於中間的AI Plus(US$4.99)反而變成尷尬選項:比免費版貴,但碰不到Pro。對重度使用者來說,直接跳AI Pro可能比卡在Plus更划算;但如果你只是偶爾問問題、抓個摘要,免費版的Flash-Lite其實還是堪用。
另外Google同時加入了「低/中/高」三種推理強度(effort level)可選,強度越高耗用的額度越多——這代表就算升級到Pro,用起來也要注意額度分配,不是無限暢用。
這次調整對重度免費用戶是個警訊:習慣白嫖Pro模型的人,10/9之後得認真考慮每月花不花這19.99美元。
好不好用,試了才知道。

🇺🇸 Gemini Free Tier Review: Flash-Lite Only After Oct 9
Google quietly rewrote the rules for Gemini's free tier starting October 9, 2026, and it is a real downgrade, not just marketing copy. Free users who previously got occasional access to Gemini 3.1 Pro now lose that entirely — along with the mid-tier Flash model — leaving only the lightweight Gemini 3.5 Flash-Lite. If you have been running anything demanding on a free account, this change hits your workflow directly.
What Each Tier Looks Like After October 9
- Free: Flash-Lite only. Flash and Pro access are both revoked.
- AI Plus (US$4.99/month): Keeps Flash-Lite and Flash, but loses Pro.
- AI Pro (US$19.99/month): Keeps all three models, and now also gets Deep Think, the advanced reasoning mode previously gated behind the US$99.99–199.99 Ultra tiers.
- AI Ultra: Unchanged — top-tier access as before.
One detail worth flagging: AI Plus subscribers are not all cut off on the same day. Google is staggering the rollout and notifying each account by email with its own transition date, so some Plus users will keep Pro access for a while after October 9 before their notice arrives.
Free Users Feel It Most
For anyone not paying, the Gemini app effectively becomes a single-model tool. Occasional access to Pro for harder reasoning or analysis is gone — what is left is Flash-Lite, fine for quick Q&A, summarization, or translation, but not built for heavier work like debugging code or reasoning over long documents. If that is part of your routine, the free tier is no longer enough.
Is AI Pro Worth the Upgrade?
This restructuring quietly makes the US$19.99/month AI Pro plan the real sweet spot: it keeps every model and now includes Deep Think, a feature that used to require the pricier Ultra plan. That leaves AI Plus at US$4.99 in an awkward spot — more expensive than free, but still locked out of Pro. For heavy users, jumping straight to AI Pro may make more sense than sitting on Plus. For light, occasional use, free Flash-Lite still gets the job done.
Google also added selectable "low / medium / high" effort levels per model — higher effort burns through your usage limit faster, so even on AI Pro, reasoning power is not unlimited.
The real takeaway: if you have been relying on free Pro access regularly, October 9 is the point where you need to decide whether that US$19.99 a month is worth it.
