Quick answer: Gemini 4 Argon has no free tier. It costs $19.99/month with Google AI Pro (Ultra from $99.99). On the API it’s $2/$10 per million input/output tokens until November 30, then the price doubles from December 1.
Argon is Google’s newest frontier reasoning model and the first in the Gemini 4 family, launched October 13, 2026 (Google blog). If you’re searching “gemini 4 argon free”, there are only two real routes: a free AI Pro year for US college students, and device trials. Both have limits.
Key takeaways
- AI Pro ($19.99) is the cheapest plan with Argon. Free Gemini and AI Plus don’t include it.
- The API has no free tier for Argon. Its price is intro pricing until November 30, then doubles from December 1.
- US college students can redeem a free AI Pro year by December 31, 2026. Students elsewhere get AI Plus, which has no Argon.
- Free AI Pro trials (Pixel, Chromebook) don’t include Argon in Google Antigravity.
Gemini 4 Argon price: plans compared
| Plan | Monthly price | Argon? | Notes |

| Free Gemini | $0 | No | Flash models only |
| Google AI Plus | $4.99 | No | 400 GB storage, Gemini 3.6 Flash |
| Google AI Pro | $19.99 | Yes (expanded) | 5 TB, 1M context, $10/mo Cloud credits, YouTube Premium Lite |

US prices from Google One. Local prices vary. Google says AI Pro and Ultra are each sold in more than 150 countries, but Argon is available only in “select countries”, so check the plan page for your country before you pay. AI Pro can also be shared with up to five family members at no extra cost.
Is Gemini 4 Argon free? Every working route (and the false ones)
1. US college students: a free year of Google AI Pro
- Who: eligible US college students. Students in more than 140 other markets get AI Plus free instead. That offer excludes Bolivia, Albania, Canada, Macau, Hong Kong and Tunisia.
- Deadline: redeem by December 31, 2026.
- Catch: you need a card at sign-up, and the plan renews at $19.99/month after 12 months.
- Argon? Yes in the US. International students get AI Plus, which has no Argon.
- Source: Google student offer, Aug 19, 2026.
2. Device trials: Pixel 11 Pro and Chromebook Plus
- Pixel 11 Pro, Pro XL and Pro Fold: 6 months of AI Pro for new and existing users. You can claim it until October 31, 2027, and it renews into a paid plan unless you cancel (Gemini Apps Help).
- Chromebook Plus: 12 months of AI Pro. Other Chromebooks get 3 months. 9to5Google also lists 12 months with a Googlebook, 6 months with a Galaxy Z Fold 8, and 6 months for select Verizon customers (9to5Google, Oct 16, 2026).
- Catch: Google classifies these as “AI Pro (Trial)” plans. In Antigravity, Argon is reserved for paid, non-trial Pro subscribers, and trial users get Gemini 3.8 Flash there instead. Switching to paid ends the trial, according to Google’s reply on its AI Developers Forum. Google hasn’t said clearly whether trials get Argon in the Gemini app, so check the model picker after you activate one.

3. Scientists: free Antigravity access by application
Google is offering 10,000 scientists the top Antigravity tier free for 6 months. Places depend on eligibility, capacity and selection (launch post).
Free claims that are false
- “Free in the Gemini app.” False. Free accounts and AI Plus don’t include Argon.
- “The API free tier includes it.” False. Google’s pricing page lists Argon as “Not available” on the free tier.
- “AI Studio is free, so Argon is free.” Misleading. AI Studio itself is free, but Google lists Argon in AI Studio as an Ultra benefit. Otherwise you need a paid API key.
- “Workspace includes it.” Unconfirmed. Google says Argon is in “Gemini for business” but doesn’t name which Workspace editions include it.
Where you can use Argon
| Surface | Plan needed |
|---|---|
| Gemini app and AI Mode in Search | AI Pro or Ultra |
| Google AI Studio | Ultra, or a paid API key |
Gemini API (gemini-4-argon) | Paid tier only |
| Google Antigravity | Ultra, or paid Pro (trials excluded) |
| Gemini for business | Business contract |
Deep Research comes with AI Pro and Ultra, but Google doesn’t say which model powers it. None of Google’s Argon pages mention a “Deep Think” mode for Argon.
Strengths and limits
According to the DeepMind model card, Argon takes text, images, audio and video as input and answers in text only. It has a 1M-token combined input/output window, and AI Pro and Ultra list 1M context in the app too. It leads Google’s comparison table on knowledge work (Vals Index 68.9%), agentic coding (DeepSWE 77.9%) and long-context recall (GraphWalks 1M, 84.2%). Google also says it hedges and repeats itself less than earlier Gemini models.
The limits: it trails a rival on FrontierSWE v2, Terminal-bench 4.0 and Terminal-Bench Science. Its knowledge cutoff is March 2026. The model card warns of hallucinations and “occasional slowness or timeout issues”. Usage caps are only described as “expanded” (Pro) or “higher” (Ultra), with no numbers. It’s available in select countries, and the app is 18+ only. On the API it supports implicit caching only.
Gemini 4 Argon API pricing: the November 30 change
| Per 1M tokens (Standard) | Until November 30 | Doubles from December 1 |
|---|---|---|
| Input | $2.00 | $4.00 |
| Output (incl. thinking) | $10.00 | $20.00 |
| Cached input | $0.10 | $0.20 |
| Batch / Flex input / output | $1.00 / $5.00 | $2.00 / $10.00 |
Grounding with Google Search is free for 5,000 requests a month, shared across Gemini 3 and newer models, then $14 per 1,000 (Gemini API pricing).
What that means in practice: a job with 100,000 input tokens and 20,000 output tokens costs about $0.40 at today’s rate and about $0.80 from December 1. Thinking tokens are billed as output, so a high-effort answer costs more than its visible length suggests. Google’s pricing page also says Argon isn’t available “on the Free tier or on the Google AI Pro plan”. In practice, a Pro subscription covers the app, not API usage. Developers need a billing-enabled API key.
Cheapest route by user type
- US college student: claim the free AI Pro year by December 31, 2026, and set a reminder before it renews.
- Student outside the US: AI Plus doesn’t include Argon, so AI Pro at $19.99 is the cheapest real option.
- Casual user: AI Pro month to month. If you’re buying a Pixel 11 Pro or Chromebook Plus anyway, use the trial first.
- Developer: use the paid API with Batch or Flex (half price) until November 30, and lean on cached input. Pro’s $10 a month in Cloud credits helps too.
- Heavy user or coder: Ultra 5x ($99.99) for Argon in Antigravity and AI Studio. Move to 20x only if you keep hitting caps.
