Gemini 4 Pro is still not a product
Only the Gemini 4 pre-training run is confirmed; the API catalog lists no gemini-4* at all
Google's official blog of 2026-07-21 says its "most ambitious pre-training run yet" for Gemini 4 has started, and the same post states Gemini 3.5 Pro is still testing with partners. In the API model catalog last updated 2026-09-17 there is no gemini-4 and no gemini-4-pro id, price or model card.
Updated 2026-09-18
What Google actually said
No 4, no 4 Pro
The model-endpoint table in the official API catalog dated 2026-09-17 lists neither gemini-4 nor 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.
Still late
The Pro tier listed as live in the catalog is Gemini 3.1 Pro, id gemini-3.1-pro-preview.
Rumor only
The catalog now lists gemini-3.8-flash and gemini-3.8-live — the 3.x line keeps growing, which is a separate fact from Gemini 4.
Why people type Gemini 4 Pro
Three things to separate when you search "Gemini 4 Pro": only one fact is officially confirmed (pre-training started 2026-07-21); the callable Pro today is gemini-3.1-pro-preview; and Gemini 3.5 Pro was still "testing with partners" in that same post. Gemini 4 is not a rename of 3.5 Pro, and there is no official id, price or benchmark.
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. The only official statement about Gemini 4 is still the 2026-07-21 pre-training line.
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*.
2026-09-18 this page was re-checked against that catalog: Gemini 4 and Gemini 4 Pro still have no model card, pricing or API id.
Confirmed vs rumor
Confirmed
Confirmed, each with a first-hand source: Gemini 4 pre-training started 2026-07-21; Gemini 3.5 Pro still testing with partners; in the catalog dated 2026-09-17 the live Pro is gemini-3.1-pro-preview, alongside gemini-3.8-flash and gemini-3.8-live.
Rumor
"Gemini 4 Pro ships in October" and "the first checkpoint leaked" have no place here: beyond the catalog dated 2026-09-17 and the 2026-07-21 blog post there is no official date, id, price or benchmark. Leaked third-party scores are never mixed with official numbers.
What to use instead
Need Google stack today
Google-side ids you can set today are the 3.x family from the catalog: gemini-3.1-pro-preview, gemini-3.8-flash, gemini-3.8-live.
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
This page stays red until Google publishes a model id (gemini-4, gemini-4-pro or otherwise) with a model card. Then rewrite benchmarks and context limits from the official card and note that the query "Gemini 4 Pro" may not match the final id.
On QCode
There is no model named Gemini 4 Pro to enable — it does not exist officially yet. This page makes no availability claim about Gemini 4; QCode's /models listing and the 30-day usage table are what determines availability.
Gemini 4 Pro FAQ
Is Gemini 4 Pro released?
No. As of 2026-09-18 the official blog only describes pre-training that started 2026-07-21, and the API catalog dated 2026-09-17 has no gemini-4-pro id.
Did Google announce Gemini 4?
On 2026-07-21 they confirmed the Gemini 4 pre-training run had started. That is not a release, and there is no SKU.
Is Gemini 4 just 3.5 Pro renamed?
It is not. Gemini 3.5 Pro is still the 3.x SKU described as "testing with partners" on 2026-07-21; Gemini 4 is the next pre-training run mentioned in the same post.
When will Gemini 4 Pro launch?
There is no official date. The catalog's own stamp reads Last updated 2026-09-17 UTC and contains no Gemini 4 row. Any specific month is not official.
What Gemini can I use for coding now?
Per the catalog dated 2026-09-17 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.
Will QCode list Gemini 4 Pro on day one?
Day one is not discussable while no model exists to enable. Watch /models and Google's model pages — those two are the evidence for what is actually callable.

Not affiliated with Google / DeepMind. "Gemini 4 Pro" is a search query, not an announced SKU. Three tiers are kept apart: the officially confirmed pre-training run, circulating rumour about dates, and what is unconfirmed — no id, price or model card. Leaked benchmarks are not release evidence.
