Gemini 3.5 Pro: When Does It Release?
Google's next flagship still has not shipped. The most recent official wording, from the 2026-07-21 blog, is only that it is "currently testing with partners" and will be made "broadly available as soon as it's ready" — with no date. The same post announced that Google had begun its most ambitious pre-training run yet, for Gemini 4. What actually shipped on 09-02 was Gemini 3.8 Flash. Here is the verified timeline, what is confirmed versus rumoured, and what you can actually use today.
As of 2026-09-09, Gemini 3.5 Pro still has not shipped. 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, what Google shipped on 2026-09-02 was Gemini 3.8 Flash and 3.8 Flash Cyber; that announcement does not update 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).
Outlets reported release dates of July 2026 and then 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.

🔮 Rumored vs confirmed
What people expect from Gemini 3.5 Pro — and what Google has actually said.
2M-token context (rumored)
Widely expected to double Gemini 3 Pro's window, but Google has not confirmed Pro specs.
Deep Think reasoning (expected)
Anticipated for the Pro tier, but not officially detailed for 3.5 Pro.
Release date: two rumoured dates have both passed, and Google has never given one
The circulated dates of July 2026 and 12 August 2026 have both come and gone without a release. Both came from financial and insider channels, and 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.
What is actually callable on QCode right now
You don't have to wait for 3.5 Pro to build with Google's models.
Gemini 3 Pro & 3.5 Flash
Both available now — 1M-context reasoning and fast multimodal work through one QCode key.
One key, three platforms
The same balance powers Claude, Codex and Gemini — switch models without re-subscribing.
3.5 Pro on launch day
We track Google's rollout and will enable Gemini 3.5 Pro for everyone as soon as it is broadly available.
Frequently asked questions
When will Gemini 3.5 Pro be released?
Google has never announced a public date. 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 and then 12 August 2026; 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, and that announcement does not update the status of 3.5 Pro.
Can I use Gemini 3.5 Pro on QCode now?
No. Google has not made 3.5 Pro generally available. As for other Gemini models: they have entries in QCode's pricing table, but we have no real call volume for the Gemini family over the last 30 days, so this page makes no availability claim — check the live state on the /models page and validate with a small test call first. What does have real traffic on QCode over the last 30 days are the Claude, GPT and Chinese open-weight lines.
What is the difference between Gemini 3.5 Flash and 3.5 Pro?
Flash (GA May 19) is the fast, cost-efficient tier and is already available. Pro is the high-capability flagship still in preview. Flash benchmarks are public; Pro specs are not.
Is there a Gemini 3.2?
No. Google moved from the 3.1 series straight to 3.5; there is no official Gemini 3.2 release.
One key for the vendors that are actually running
Activate a plan from $8.57/mo to use Gemini 3 Pro and 3.5 Flash — and we'll switch on 3.5 Pro for the same key the moment it launches.
