Gemini 4 Pro is still not an official model name
The live Gemini 4 models are Gemini 4 Hydrogen (gemini-4-hydrogen, GA 2026-11-12), Gemini 4 Carbon (gemini-4-carbon, GA 2026-11-10) and Gemini 4 Argon (gemini-4-argon, GA 2026-10-13); the official catalog has no id called gemini-4 or gemini-4-pro
As of 2026-11-12, Google's official Gemini API documentation has no model called Gemini 4 Pro. The Gemini 4 family now has three live models: Gemini 4 Hydrogen (id gemini-4-hydrogen), generally available since 2026-11-12, Gemini 4 Carbon (id gemini-4-carbon), generally available since 2026-11-10, and Gemini 4 Argon (id gemini-4-argon), generally available since 2026-10-13. Google's release notes call Carbon its most capable reasoning model, built for sustained agentic coding, multimodal knowledge work, scientific reasoning and cybersecurity defense, and put Hydrogen on the Free tier and at $1.50 / $7.50 per 1M input / output tokens on the paid tier; the model pages state that all three use a unified 1M context window with long decodes up to 1M tokens, with 65,536 output tokens by default in synchronous mode and up to 1M with long decode. The earlier official record still holds too: the official blog of 2026-07-21 said the Gemini 4 pre-training run had started and the same post states Gemini 3.5 Pro is still testing with partners, and the API model catalog last updated 2026-09-24, re-checked 2026-09-29, had neither a gemini-4 nor a gemini-4-pro id, price or model card.

What Google actually said
The live 4-family model
The official release notes mark Gemini 4 Hydrogen (gemini-4-hydrogen) as generally available on 2026-11-12, Gemini 4 Carbon (gemini-4-carbon) on 2026-11-10 and Gemini 4 Argon (gemini-4-argon) on 2026-10-13; the official deprecation table still lists no shutdown date for any of the three rows. The catalog dated 2026-09-24 had neither a gemini-4 nor a gemini-4-pro.
Pre-training started
Official blog: the Gemini 4 pre-training run has started. That is not a release and there is no SKU; the release itself came on 2026-10-13.
The live Pro is unchanged
The Pro tier listed as live in the official catalog is still Gemini 3.1 Pro, id gemini-3.1-pro-preview; the release notes, the model page and the deprecation table do not carry the name Gemini 4 Pro.
In catalog
The official catalog lists gemini-3.8-flash and gemini-3.8-live — the 3.x line keeps growing, which is a separate fact from Gemini 4; the shutdown date in the deprecation table for gemini-3.1-pro-preview reads No shutdown date announced.
Why people type Gemini 4 Pro
Three things to separate when you search Gemini 4 Pro: the first officially confirmed fact is that pre-training started on 2026-07-21, and the same post says Gemini 3.5 Pro is still testing with partners; the live Pro in the official catalog is gemini-3.1-pro-preview, alongside gemini-3.8-flash and gemini-3.8-live; and the Gemini 4 family now has three live models, gemini-4-hydrogen (GA 2026-11-12), gemini-4-carbon (GA 2026-11-10) and gemini-4-argon (GA 2026-10-13), while the official documentation has never carried a model called Gemini 4 Pro. Gemini 4 is not a rename of 3.5 Pro.
The competitive context
Re-checked 2026-09-18 against the catalog dated 2026-09-17: what was added is gemini-3.8-flash and gemini-3.8-live, not Gemini 4, and the only official statement about Gemini 4 was still the 2026-07-21 pre-training line. On 2026-10-08, Google marked gemini-3.7-flash as deprecated: it is no longer available to select in Google AI Studio, and API requests to it are automatically routed to gemini-3.8-flash. On 2026-10-13, the Gemini 4 family went GA under the name Gemini 4 Argon, and on 2026-11-10 Google added the family's second model, Gemini 4 Carbon (gemini-4-carbon), with introductory pricing and the 2026-11-30 window in the same release-notes entry, and on 2026-11-12 its third, Gemini 4 Hydrogen (gemini-4-hydrogen), on the Free tier and at $1.50 / $7.50 per 1M input / output tokens on the paid tier.
Public crumbs
2026-07-21 Google's official blog confirms the Gemini 4 pre-training run has started and that Gemini 3.5 Pro is still testing with partners.
2026-09-17 (catalog marked "Last updated 2026-09-17 UTC"): the API catalog added gemini-3.8-flash and gemini-3.8-live, and still has no gemini-4*.
2026-10-19: this page was re-checked against the official release notes, the model page and the deprecation table, and the official documentation carries no model called Gemini 4 Pro; in the same window Google marked gemini-3.7-flash as deprecated on 2026-10-08, with API requests to it routed automatically to gemini-3.8-flash, and on 2026-10-13 the Gemini 4 family went GA as Gemini 4 Argon; the catalog dated 2026-09-24, re-checked 2026-09-29, had no gemini-4 and no gemini-4-pro id either.
Confirmed vs rumor
Confirmed
Confirmed, each with a first-hand source: Gemini 4 Hydrogen (gemini-4-hydrogen) went generally available on 2026-11-12, and the release notes say it is available on the Free tier and at $1.50 per 1M input tokens and $7.50 per 1M output tokens on the paid tier; Gemini 4 Carbon (gemini-4-carbon) went generally available on 2026-11-10, and the release notes call it Google's most capable reasoning model, built for sustained agentic coding, multimodal knowledge work, scientific reasoning and cybersecurity defense, at an introductory price of $2.00 per 1M input tokens and $10.00 per 1M output tokens through 2026-11-30, which the same entry says becomes $4.00 per 1M input and $20.00 per 1M output afterwards; the Gemini 4 pre-training run started 2026-07-21, and the same post states Gemini 3.5 Pro is still testing with partners; in the API catalog dated 2026-09-24 and re-checked 2026-09-29 the live Pro is gemini-3.1-pro-preview, alongside gemini-3.8-flash and gemini-3.8-live; on 2026-10-08 Google marked gemini-3.7-flash as deprecated, with API requests routed automatically to gemini-3.8-flash; and on 2026-10-13 Gemini 4 Argon (gemini-4-argon) went generally available, marked Released in the release notes, which Google calls its most capable model for complex coding, agentic, math and science tasks, with a unified 1M context window and long decodes up to 1M tokens on the model page.
Rumor
"Gemini 4 Pro ships in October" and "the first checkpoint leaked" have no source in the official documentation: beyond the catalog dated 2026-09-17 and the 2026-07-21 blog post there is no official date, id, price or benchmark, and leaked third-party scores are never mixed with official numbers. The models that went GA on 2026-10-13, 2026-11-10 and 2026-11-12 are Gemini 4 Argon (gemini-4-argon), Gemini 4 Carbon (gemini-4-carbon) and Gemini 4 Hydrogen (gemini-4-hydrogen); the official documentation still carries no model called Gemini 4 Pro.
What to use instead
Need Google stack today
The ids listed in the Google catalog today: gemini-4-hydrogen, gemini-4-carbon and gemini-4-argon (the 4 family), gemini-3.1-pro-preview, gemini-3.8-flash and gemini-3.8-live, all straight from the official catalog.
Need 2026 frontier coding
gemini-4-pro is not in the official catalog, so a config that sets it gets no response.
How this page flips green
The model id Google ends up publishing may be gemini-4, gemini-4-pro or something else — the names in the official documentation today are Hydrogen, Carbon and Argon, none of them Pro. Benchmarks and context limits follow the official model card: the Gemini 4 family model cards are in Google's Gemini API documentation (ai.google.dev), where Gemini 4 Argon (gemini-4-argon) went GA on 2026-10-13 Gemini 4 Carbon (gemini-4-carbon) on 2026-11-10 and Gemini 4 Hydrogen (gemini-4-hydrogen) on 2026-11-12, all with a unified 1M context window and long decodes up to 1M tokens.

Gemini 4 Pro FAQ
Is Gemini 4 Pro released?
No. Per the catalog dated 2026-09-24 and re-checked 2026-09-29, there is no gemini-4-pro id, and the official blog post of 2026-07-21 only describes the pre-training that started that day. As of the 2026-11-12 re-check, the live models in the Gemini 4 family are Gemini 4 Hydrogen (id gemini-4-hydrogen, GA 2026-11-12), Gemini 4 Carbon (id gemini-4-carbon, GA 2026-11-10) and Gemini 4 Argon (id gemini-4-argon, GA 2026-10-13), and the official documentation carries no name Gemini 4 Pro.
Did Google announce Gemini 4?
It was announced, but not under the name Pro. The official blog of 2026-07-21 said the Gemini 4 pre-training run had started; the release notes of 2026-10-13 mark Gemini 4 Argon (gemini-4-argon) as generally available, and the banner at the top of Google's docs says Gemini 4 Argon is now available. Google calls Gemini 4 Argon its most capable model, built for complex coding, agentic, math and science tasks.
Is Gemini 4 just 3.5 Pro renamed?
It is not a rename. Gemini 3.5 Pro is still the 3.x SKU described as "testing with partners" on 2026-07-21, and Gemini 4 is the next pre-training run mentioned in the same post; what went GA on 2026-10-13 is the new model name Gemini 4 Argon (id gemini-4-argon), and there is no renaming note in the official record.
When will Gemini 4 Pro launch?
There is no official date. The catalog's own stamp reads Last updated 2026-09-24 UTC (re-checked 2026-09-29) and contains no Gemini 4 row; in the official deprecation table the Gemini 3 rows, for example gemini-3.1-pro-preview, read No shutdown date announced, and the same page says the shutdown dates in that table are the earliest possible dates on which a model might be retired, not fixed dates. Any specific month is not official.
What Gemini can I use for coding now?
Per the catalog dated 2026-09-24 (re-checked 2026-09-29) the coding-side choices are gemini-3.1-pro-preview, gemini-3.8-flash and gemini-3.8-live; read each model card for actual capability. As of 2026-11-12, the live models in the Gemini 4 family are Gemini 4 Hydrogen (GA 2026-11-12), Gemini 4 Carbon (GA 2026-11-10) and Gemini 4 Argon (GA 2026-10-13), all with a unified 1M context window and long decodes up to 1M tokens; the Gemini series is not currently offered on QCode, and for coding you can pick claude-sonnet-5-5, gpt-6.1-sol and glm-5.3.
Will QCode list Gemini 4 Pro on day one?
No. QCode does not offer the Gemini series for now, and there is no model called Gemini 4 Pro in the official docs. Models you can call on QCode include claude-sonnet-5-5, gpt-6.1-sol and glm-5.3, billed per token, with per-model rates on /models.
