Gemini 3.5 Pro: When Does It Release?
Google has not announced a release date for Gemini 3.5 Pro: as of 2026-11-10, the official Gemini API models page and release notes (latest entry 2026-11-06) show neither a date nor an entry for it, and the newest Pro model in the Gemini 3 family on the models page is still Gemini 3.1 Pro (gemini-3.1-pro-preview). The most recent official mention is the 2026-07-21 blog, which says only that it is "currently testing with partners" and will be made "broadly available as soon as it's ready", with no date. Since then Google has moved on to the Gemini 4 line: Gemini 4 Argon (gemini-4-argon) became generally available (GA) on 2026-10-13, and Gemini 4 Carbon was announced on 2026-10-28 — Google says it goes first to a subset of cyber defenders and will reach developers "as soon as possible"; the Gemini API models page and release notes do not list Carbon yet. Below is the verified timeline and what is confirmed versus rumoured.

As of 2026-11-10, no record of a Gemini 3.5 Pro release turns up on the official Gemini API models page or release notes. The newest Pro model in the Gemini 3 family on the models page is Gemini 3.1 Pro (gemini-3.1-pro-preview; the deprecations page gives its release date as 2026-02-19 and announces no shutdown date), with no 3.5 Pro entry, and the newest release-notes entry, dated 2026-11-06 (the Gemini Embedding 2 Preview deprecation notice), does not mention 3.5 Pro either. The most recent checkable official statement is from the 2026-07-21 blog: "Gemini 3.5 Pro is currently testing with partners and we plan to make it broadly available as soon as it's ready" — no date of any kind. The same post also announced that Google had started its most ambitious pre-training run yet, for Gemini 4. Since then Google has shipped Gemini 3.8 Flash (2026-09-02) and Gemini 4 Argon and announced Gemini 4 Carbon; none of those announcements updates the status of 3.5 Pro.
When will Gemini 3.5 Pro release?
The verified Gemini timeline leading up to 3.5 Pro.
Launched with a 1M-token context window (LMArena Elo 1501).
Released for complex, long-horizon agentic and multimodal coding.
Shipped at Google I/O to billions of users via the Gemini app, Search AI Mode and the API.
Google said the Pro model was in internal use and would arrive 'next month' (around June).
Enterprise DNA, citing Business Insider, reported on 2026-06-25 that general availability had slipped to July 2026; on 2026-08-04 nokiapoweruser.com, citing community leaks, named 12 August 2026. Both passed with no release and no confirmed new date from Google. The only checkable official statement remains the 2026-07-21 blog's "currently testing with partners… broadly available as soon as it's ready". For contrast: what Google actually shipped on 2026-09-02 was Gemini 3.8 Flash and 3.8 Flash Cyber. Checked again on 2026-11-10: the newest entry in the official Gemini API release notes (2026-11-06, the Gemini Embedding 2 Preview deprecation notice) still does not mention 3.5 Pro.

🔮 Rumored vs confirmed
What people expect from Gemini 3.5 Pro — and what Google has actually said.
2M-token context (rumored)
Enterprise DNA (2026-06-25) and a nokiapoweruser.com leak roundup (2026-08-04) both said 3.5 Pro would get a 2M-token context window, double Gemini 3 Pro's; Google has not confirmed Pro specs.
Deep Think reasoning (expected)
Enterprise DNA (2026-06-25) reported that 3.5 Pro was still targeting a Deep Think reasoning mode; Google has not detailed Deep Think for 3.5 Pro.
Release date: two rumoured dates have both passed, and Google has never given one
The two circulated dates have both come and gone without a release: July 2026 (Enterprise DNA, 2026-06-25, citing Business Insider) and 12 August 2026 (nokiapoweruser.com, 2026-08-04, citing community leaks). Google confirmed neither. The only checkable official phrasing is "broadly available as soon as it's ready", which contains no date. Do not plan around any circulating date; this page will not chase further rumoured dates either, only official statements.
There is no Gemini 3.2
Google skipped 3.2 and moved straight to the 3.5 family — ignore any '3.2' claims.
Pricing, context window and benchmarks for Gemini 3.5 Pro are unofficial until Google publishes them. We'll update this page on launch.
While 3.5 Pro is pending: what Google's docs say today
The cards below summarise what Google's own documentation says today.
Newest flagship: Gemini 4 Argon
As of 2026-11-10 the Gemini 4 section of the official models page lists only Gemini 4 Argon (gemini-4-argon, 1M-token context), and the release notes record it as generally available (GA) on 2026-10-13. Gemini 4 Carbon was announced on 2026-10-28 and, per Google, goes first to a subset of cyber defenders; the models page and release notes do not list it. The 2026-09-18 release notes, which limited access to the 2.5 models, tell new projects to use 3.5 Flash-Lite or 3.8 Flash.
Pro tier: Gemini 3.1 Pro
As of 2026-11-10 the newest Pro model in the Gemini 3 family on the official Gemini API models page is Gemini 3.1 Pro (gemini-3.1-pro-preview). gemini-2.5-pro is deprecated: the official release notes (2026-11-02) say that from 2026-12-01 all API requests to it route automatically to gemini-3.8-flash and are billed at Gemini 3.8 Flash rates.
This page follows official sources only
Once 3.5 Pro appears on the Gemini API models page or in the release notes, this page will be updated from there. When you need a per-token coding-model API, QCode offers Claude, GPT and Chinese models (e.g. claude-sonnet-5-5, gpt-6.1-sol, glm-5.3); each model's price is on /models.
Frequently asked questions
When will Gemini 3.5 Pro be released?
Google has not given a date: as of 2026-11-10 no public date turns up on the official Gemini API models page or release notes: the models page has no 3.5 Pro (its newest Pro model in the Gemini 3 family is Gemini 3.1 Pro), and the newest release-notes entry, dated 2026-11-06, does not mention it. The most recent checkable official wording is from the 2026-07-21 blog: "currently testing with partners… broadly available as soon as it's ready". Outlets previously reported July 2026 (Enterprise DNA, 2026-06-25, citing Business Insider) and then 12 August 2026 (nokiapoweruser.com, 2026-08-04); both dates passed without a release and Google confirmed neither. What Google actually shipped on 2026-09-02 was Gemini 3.8 Flash and 3.8 Flash Cyber; the later Gemini 4 Argon and Gemini 4 Carbon announcements do not update the status of 3.5 Pro either.
Gemini 3.5 Pro isn't out yet. Which coding models does QCode offer right now?
As of 2026-11-10, 3.5 Pro has no entry on the official Gemini API models page. When you need a per-token coding-model API, QCode offers Claude, GPT and Chinese models (e.g. claude-sonnet-5-5, gpt-6.1-sol, glm-5.3); each model's price is on /models, and one key covers them all. Not ready for a monthly plan? Pay-as-you-go Packs give you a one-time quota to use within 7 days (see /pay-as-you-go); if you already have a Personal Plan, add a booster pack when you need more quota.
What is the difference between Gemini 3.5 Flash and 3.5 Pro?
Flash is the fast, cost-efficient tier; Pro is the high-capability flagship tier. On the Flash side, Gemini 3.5 Flash went GA on May 19, 2026, and the official release notes record it as deprecated since 2026-10-08, with requests routed automatically to Gemini 3.6 Flash. On the Pro side, as of 2026-11-10 the official models page still has no 3.5 Pro entry; the newest Pro model it lists is Gemini 3.1 Pro (gemini-3.1-pro-preview), a preview model. Flash benchmarks are public; 3.5 Pro specs are not.
Is there a Gemini 3.2, and what are Gemini 4 Argon and Carbon?
No. Google moved from the 3.1 series straight to 3.5; there is no official Gemini 3.2 release. Gemini 4 Argon (gemini-4-argon) is the only model in the Gemini 4 section of the official models page and has been generally available since 2026-10-13; Gemini 4 Carbon was announced on 2026-10-28 and goes first to a subset of cyber defenders, with developers given only "as soon as possible". As of 2026-11-10 neither the models page nor the release notes list a model called Gemini 4 Pro.
One key for the models QCode actually serves
QCode serves models such as claude-sonnet-5-5, claude-opus-5-5, gpt-6.1-sol, deepseek-v4-pro, glm-5.3 and kimi-k3, billed per token; each model's price is on /models.
