NT$0/month, free to anyone with a Google account. Model available: Gemini 3.6 Flash; the official site states plainly that access to 3.1 Pro may vary, meaning free-tier access to Pro fluctuates and is not guaranteed. Features included on the free tier: image generation and editing, Deep Research, Gemini Live, Canvas, Gems, Gemini Notebook (research and writing), the Google Flow creative studio, plus limited usage of Nano Banana Pro. Cloud storage 15 GB (shared across Gmail/Drive/Photos). How the quota is counted and when it resets, in the official footnote's own words: the Gemini app measures usage limits by compute, which depends on prompt complexity, the features you use and conversation length; usage resets every 5 hours, up to a weekly usage cap. In other words the free tier is not a fixed number of messages per day but a compute allowance that resets every 5 hours plus an overall weekly cap; long conversations, Deep Research and image generation burn through it faster than plain chat. When the quota runs out you can buy AI credits. The official site does not publish the specific compute figure for the free tier.

The official site publishes no concrete usage figures at all for the free tier, and this site does not fill in an estimate. Verification trail (exhausted): grok.com/pricing returns HTTP 200 but the whole page is rendered by JavaScript, so the static HTML contains no plan names or price text, only Stripe price IDs; opening it in a real browser hits a Cloudflare human-verification wall, which we do not bypass; x.ai/grok returned 403 three times in a row (blocked, not 404). What can be confirmed: free use does exist and is US$0, because in the in-app purchase list on the official Apple App Store listing every paid item belongs to the SuperGrok range, so basic chat requires no payment. Third-party felloai.com states plainly that xAI has never published free-tier numbers anywhere, and says the free tier only gets the lighter Grok 4 Mini, includes basic real-time web and X search, has limited voice mode, and that image and video generation were removed from the free tier on 2026-03-19. The widely circulated figure of about 10 messages every 2 hours has no official backing and is not used here. (Verified 2026-08-09)
