Quick answer
For Gemini 4 Argon, Google AI Pro (about $20 a month) gives you Argon in the Gemini app and in AI mode in Search, which covers most writing, research and planning work. Google AI Ultra (about $100 a month) also unlocks Argon inside Antigravity, Google's coding environment. Choose Pro unless someone on your team will use Antigravity for coding every week.
Key takeaways
- Pro (about $20/month): Argon in the Gemini app and Search AI mode
- Ultra (about $100/month): adds Argon in Antigravity for coding
- Most non-coders only need Pro
- Upgrade one person first and prove the value
This guide answers one question from our article Gemini 4 Argon Review: Has Google Finally Caught Up?: which Google plan does your team actually need to use Argon?
📘 Main article: This guide supports our full article, Gemini 4 Argon Review: Has Google Finally Caught Up?. Read it for the complete picture.
What does each plan include for Argon?
Based on Matt Wolfe's review, as summarised in our main article:
⚠️ Warning: Plan contents and prices are as reported in Matt Wolfe's review at the time. Check Google's current plan page and availability in your country before you buy.
| Feature | Google AI Pro | Google AI Ultra |
|---|---|---|
| Reported price | From about $20/month | From about $100/month |
| Argon in the Gemini app | Yes | Yes |
| Argon in Search AI mode | Yes | Yes |
| Chat and tasks in the Gemini app | Yes | Yes |
| Argon in Antigravity (coding) | No | Yes |
The API is a separate route with its own token pricing. Our Argon API cost guide covers that.
Who is Pro right for?
Pro suits anyone whose work happens in chat and search:
- Writing and editing content
- Product and market research
- Planning and scheduling problems
- Everyday questions where you want more direct answers
Google says Argon should give more direct answers, use fewer clichés and follow style instructions more reliably than earlier Gemini models. Those improvements arrive on Pro.
The Gemini app also lets you switch between chat and tasks, with connectors to everyday apps such as Instacart, OpenTable, Adobe and Shopify.
Who needs Ultra?
Ultra mainly earns its price for people who code. Antigravity is Google's coding environment, positioned against tools like Codex and Claude Code. In the review, Argon appeared there in low, medium and high effort modes, and Ultra was required for that surface.
Consider Ultra if a team member:
- Builds or maintains code most weeks
- Wants to compare Argon against their current coding agent on a real repository
- Already works mainly in Google's tools
If nobody codes regularly, Ultra is likely to be an expensive extra.
How do you decide for a small team?
- List each person and their main AI tasks.
- Mark anyone who codes at least weekly.
- Put everyone else on Pro.
- Put one coder on Ultra for a month as a trial.
- Compare Argon in Antigravity against their current coding tool on the same tasks.
- Add more Ultra seats only if the trial clearly wins.
Start everyone on Pro and upgrade only where the trial clearly wins.
💡 Tip: Start everyone on Pro and upgrade only the person who will use Antigravity every week. You can always add more Ultra seats later.
Decide per person, not per team. List who codes weekly; everyone else starts on Pro.
What about early-access issues?
Our main article noted that task mode looked buggy in early access: research and slide-deck jobs stalled for about an hour in Matt Wolfe's tests, even when a deck had already been produced. He flagged that his demo build may still have had bugs.
That applies on both plans. Do not rely on task mode for urgent work until you have tested it yourself.
How does this fit with your other AI subscriptions?
Many small businesses already pay for ChatGPT or Claude. Before adding Google, ask:
- Does your team already live in Google Workspace? Our main article noted that Google's durable advantage is its ecosystem: Gmail, Calendar, Chrome and Search.
- Would Argon replace an existing plan, or sit alongside it?
- Have you run a short trial on real work?
