Gemini 4 tracker: Argon is GA, with specs and prices here
As of 2026-10-20, Gemini 4 has shipped as Gemini 4 Argon: GA on 2026-10-13, with a unified 1,048,576-token context, a default max output of 65,536 tokens, and an official price of $2 per 1M input / $10 per 1M output through 2026-11-30, then $4 / $20. The pre-release timeline: on 2026-07-21 Google wrote on its official blog, "We have started our most ambitious pre-training run yet, for Gemini 4, and are excited by the progress." The next day, 2026-07-22, Sundar Pichai repeated the same sentence on Alphabet's Q2 2026 earnings call. QCode does not currently offer the Gemini series.

Before and after release: four checkable points
First official mention of Gemini 4
Official wording: "We have started our most ambitious pre-training run yet, for Gemini 4, and are excited by the progress." It appears in the Gemini 3.6 Flash launch post, the first time Google named the project publicly.
Repeated by the CEO on an earnings call
Sundar Pichai said the same sentence on Alphabet's Q2 2026 earnings call, ending with "we are seeing at the frontier". The same phrasing in an earnings setting means it is reviewed, official language rather than an aside.
The easiest sentence to misread
Google said pre-training has started. After pre-training come post-training, evaluations, safety review and staged rollout. No timing of any kind was given, so reading "started pre-training" as "about to ship" has nothing behind it.
3.5 Pro has still not shipped
The same post says Gemini 3.5 Pro is "currently testing with partners" and will be made "broadly available as soon as it's ready", and that Google looks "forward to releasing 3.5 Pro soon". From 2026-07-21 to this page's re-check on 2026-09-29 that is 70 days, and the official Gemini API model directory still lists no 3.5 Pro. Gemini 4 Argon reached GA on 2026-10-13; 3.5 Pro is still not on the official model page.
Where Gemini 4 stands now
Before 2026-10-13, the entire public statement on Gemini 4 was one sentence: the most ambitious pre-training run yet has started. That confirmed three things - the project exists, it has a name, and training has begun. It did not confirm a release date, price, context length, API model id or any benchmark number. On 2026-10-13, Gemini 4 Argon (gemini-4-argon) reached GA; the official model page lists a unified 1,048,576-token context, a default max output of 65,536 tokens (up to 1,048,576 with long decode), and an official price of $2 per 1M input and $10 per 1M output through 2026-11-30, then $4 / $20. Google has reordered its version naming before: what followed 3.5 Pro were 3.6 Flash and 3.8 Flash rather than 4, and 3.5 Pro is still not on the official model page as of 2026-10-20. QCode does not currently offer the Gemini series.
From "3.5 Pro has not shipped" to Argon GA: a three-month turn
On 2026-10-13 Gemini 4 Argon reached GA, closing a three-month wait. Before that, the 2026-07-21 official post said only that the most ambitious pre-training run had started; outlets reported July 2026 and then 12 August 2026 for 3.5 Pro, both dates passed without a release, and Google never confirmed either one. In the same period, Gemini 3.7 Flash was deprecated on 2026-10-08 and automatically routed to 3.8 Flash. Three things are checkable now: the model id is gemini-4-argon, the context is 1,048,576 tokens, and the official price is $2 / $10 through 2026-11-30. As of 2026-10-20, 3.5 Pro is still absent from the official model list.
Timeline (all checkable)
Google launches Gemini 3.6 Flash and others; the post closes by naming Gemini 4 and saying the most ambitious pre-training run yet has begun, while 3.5 Pro is testing with partners.
Sundar Pichai repeats the same wording on Alphabet's Q2 2026 earnings call, adding "we are seeing at the frontier".
On 2026-09-02 Google shipped Gemini 3.8 Flash and 3.8 Flash Cyber; 3.7 Flash was deprecated on 2026-10-08 and automatically routed to 3.8 Flash; on 2026-10-13, Gemini 4 Argon (gemini-4-argon) reached GA. Compared with the 07-21 pre-training sentence, the official position has now landed; 3.5 Pro is still not on the official model page as of 2026-10-20.
Three tiers: released, unpublished, and the QCode status
Officially confirmed (quotable)
1. On 2026-10-13 Gemini 4 Argon (gemini-4-argon) reached GA, positioned by Google as a flagship reasoning model for complex software engineering, math and science, and autonomous agents. 2. The unified context is 1,048,576 tokens, with a default max output of 65,536 tokens and long decode up to 1,048,576. 3. The official price is $2 input / $10 output per 1M tokens through 2026-11-30, then $4 / $20 from 2026-12-01. 4. The pre-release record: the 2026-07-21 blog post first named Gemini 4 and said pre-training had started, and the 2026-07-22 earnings call repeated it; on 2026-09-29 (model directory updated 2026-09-24 UTC) neither 3.5 Pro nor Gemini 4 was listed, and 3.5 Pro is still absent now that Gemini 4 is GA. Items 1-3 come from the 2026-10-13 release notes, model page and pricing page; item 4 from the pre-release official sources and that day's check.
Not published by Google (do not plan around it)
Google has not published any further Gemini 4 variants, a release date for 3.5 Pro, or specs beyond Argon. The two dates that circulated for 3.5 Pro (July 2026 and 12 August 2026) both passed without a release and were never confirmed by Google; as of 2026-10-20, 3.5 Pro is still absent from the official model list. This page tracks official statements only. One sentence for your team: Gemini 4 Argon is GA with published specs and prices, while 3.5 Pro is still not on the official model page.
The released Gemini 4 and what is still pending
Gemini 4 Argon (GA)
Gemini 4 Argon (GA 2026-10-13, unified 1,048,576-token context, official price $2 input / $10 output per 1M tokens through 2026-11-30) has shipped. Earlier, 3.6 Flash (2026-07-21), 3.8 Flash and 3.8 Flash Cyber (2026-09-02) had already shipped; the published entry price for 3.8 Flash is $0.75 per 1M input tokens and $3.75 per 1M output, stated by Google as an introductory rate expiring 2026-12-31, after which it becomes $1.50 / $7.50.
3.5 Pro and later versions
3.5 Pro is still absent from the official model list, with no broad-availability date. Google has not published other Gemini 4 tiers beyond Argon, and no speculation is offered here.
What is worth doing while you wait
Per Google's official documentation, gemini-4-argon lets you choose a thinking level (low, medium or high) per task and decide whether long decode is needed (QCode does not currently offer the Gemini series). Move the model name into configuration so switching models is one line rather than a code change. That matters even more across vendors: the Gemini and OpenAI families differ in interface, parameter naming and tool-call shape, and collecting those differences into one adapter layer beats scattering conditionals through business logic. The second thing worth doing now is measuring a cost baseline for your real workload on a model you can already call. Without a baseline you cannot tell whether a newly released model is cheaper or more expensive for you specifically, and you end up following someone else's benchmark. Neither task depends on anything unreleased.
The honest status of Gemini on QCode
QCode does not currently offer the Gemini series; please use Claude, GPT or Chinese models such as claude-sonnet-5-5, gpt-6.1-sol or glm-5.3. Not ready for a monthly plan? Pay-as-you-go Packs start at $4 for a one-time quota you use within 7 days; if you have an active Personal Plan you cannot buy a pack, so buy a booster pack when the plan quota is short.
Frequently asked questions
When will Gemini 4 be released?
Released on 2026-10-13: Google's Gemini API release notes list Gemini 4 Argon (gemini-4-argon) as generally available (GA) that day. Before that, the only official wording was the 2026-07-21 line that pre-training had started, with no date. As of 2026-10-20, 3.5 Pro is still not on the official model page.
What are Gemini 4 Argon's context and price?
On 2026-10-13 Gemini 4 Argon reached GA, and the official model page lists a unified 1,048,576-token context, a default max output of 65,536 tokens, and an official price of $2 / $10 through 2026-11-30. Before that, Google said only that pre-training had begun, not how far along it was or when it would end.
Gemini 4 is out - what about 3.5 Pro?
Google originally described them side by side: 3.5 Pro was testing with partners and would be broadly available when ready, while in parallel the team had begun pre-training the next generation. At the time, that placed Gemini 4 behind 3.5 Pro. On 2026-10-13 Gemini 4 Argon reached GA, while 3.5 Pro is still not on the official model page as of 2026-10-20, so the actual order differed from the July wording.
Why did 3.6 and 3.8 Flash ship instead of 4?
Gemini version numbers are not a strict release order. What followed 3.5 Pro were 3.6 Flash (2026-07-21) and 3.8 Flash (2026-09-02), both in the Flash tier. The Pro tier and the next major generation move on a different cadence, and Google has never explained the numbering scheme, so version size cannot be used to infer what ships first.
Can I use Gemini on QCode right now?
No. QCode does not currently offer the Gemini series; please use Claude, GPT or Chinese models such as claude-sonnet-5-5, gpt-6.1-sol or glm-5.3.
Should I wait for Gemini 4 or pick something available now?
Gemini 4 Argon reached GA on 2026-10-13, so there is nothing left to wait for. QCode does not currently offer the Gemini series; on QCode choose Claude, GPT or Chinese models. Whichever model you use, build the adapter layer and cost baseline first, so evaluating a new model means running a comparison you already have.
