You have probably been burned by an AI pilot that looked cheap in week one and ruinous by month three. Google has just handed Nigerian teams a rare thing: a flagship model with the price tag printed on it, and the expiry date, too.
On 13 October, Google made Gemini 4 Argon generally available. The introductory price is $2 per million input tokens and $10 per million output tokens. On 1 December, it doubles. That is a six-week window to find out whether Argon earns a place in your product before the bill changes.
What actually happened
Argon was announced on 30 September and, according to 9to5Google's report of the announcement, started out limited to trusted testers and cyber defenders through Google's Fairwind Program. Google's own launch post dated 13 October says it is now globally available through the paid Gemini API tier, Google AI Studio, Android Studio, Google Cloud and the Gemini app for Pro and Ultra subscribers. The Antigravity coding environment is limited to Ultra.
It also arrives after a stumble. Resultsense reports that Google dropped Gemini 3.5 Pro, which had been promised for June, and replaced it with Argon. Reuters, as relayed by The American Bazaar, links the launch to DeepMind leadership changes. Treat the detail of that reshuffle with care: Resultsense says Demis Hassabis stepped aside as chief executive, while a republished wire summary says only that he moved to a secondary role. Neither outlet quotes Google on it.
The price, in naira
Google's pricing page confirms the headline rates and adds detail the news coverage skipped. Standard global pricing is $2 input and $10 output until 30 November, then $4 and $20 from 1 December. Cached input starts at $0.10 per million. Batch jobs run at half the standard rate.
Using the official rate of roughly ₦1,332 to the dollar (Techeconomy's 14 October report, which notes that figure dates from 13 October), one million input plus one million output tokens costs about ₦16,000 today. From December, about ₦32,000. Not every team will hit those volumes, but an agent that loops through documents all day will get there fast.
- Check your endpoint. Google Cloud lists non-global endpoints at about 10 percent more ($2.20 and $11).
- Check the credits. Google Cloud also lists 50 percent credits back on net spend through 30 November, a sweetener the consumer-facing coverage does not mention.
- Check the exchange rate. Parallel-market quotes that day were ₦1,365 to ₦1,375.
How good is it, really?
Depends who is scoring. Google says Argon ranks first on the Vals Index, a measure of finance, coding, legal and tax work. VentureBeat's write-up puts the score at 68.90 percent, narrowly ahead of Claude Sonnet 5.5 at 67.04 percent. But on the independent Artificial Analysis Intelligence Index, VentureBeat reports Argon at 53, behind Claude Opus 5.5 (58) and Sonnet 5.5 (56). It also trails Opus on Terminal-Bench 4.0, 57.4 percent against 66.4 percent.
Most of the figures are Google-reported or previously disclosed. Independent developer Sam Witteveen, quoted by VentureBeat, called it a really good model while doubting it is the best available. Developers Digest, writing earlier in the rollout, advised against planning a production migration until model IDs, pricing and quotas were visible in normal developer channels.
Where the sources disagree
Two seams are worth knowing about. First, pricing permanence: early commentary, summarised by Developers Digest, said no end date for the discount had been announced. Google's launch post and pricing page now say it ends on 30 November. Plan on the date, not the rumour.
Second, the context claim. Google describes a combined input-and-output limit of 1 million tokens, while 9to5Google frames it as a 1 million token output limit, up from 64,000. VentureBeat notes that the relationship between the two is unclear. Test your longest real documents before you promise anything to a client.
The consumer side, and the catch
Technext reports Nigerian prices of ₦28,500 a month for Google AI Pro and ₦89,000 to ₦289,000 for Ultra, and says free accounts see the model listed but locked. Technext does not say when those prices take effect, so confirm in the app. Google is also offering 10,000 scientists six months of top-tier Antigravity access, which is worth a look for Nigerian university labs.
What to do before 1 December
Pick two or three workloads that actually cost you money today, such as contract review, support triage, or code migration, and run them on Argon with real data this month. Log tokens per task. Compare against your current model on cost per finished task, not cost per token.
Then decide: keep it, route only the hard jobs to it, or walk away. Doing that in October costs half of doing it in December. Budget the post-promo price in naira, not dollars, because that is what your finance team will see.
Which workload in your business would you test on Argon first, and what would it have to save you to justify the December price?
