If you saw headlines in May about a powerful new Google AI called Gemini 3.5 Pro and have been waiting to try it, here's a plain-English guide to what's actually going on — and what you can use right now.

> **Info:** 💡 **In plain English:** Google announced two new AI models at its big May event. The fast one (Flash) came out the same day and you can use it. The powerful one (Pro) was only *announced* — Google said it would arrive 'next month', but as of late June it still isn't available to the public.

## What Google actually said

At Google I/O — Google's annual technology event — on **19 May 2026**, Google introduced **Gemini 3.5**. It released **Gemini 3.5 Flash**, a fast, low-cost model, and made it the default in the Gemini app and in Google Search's AI Mode straight away. At the same time, it *announced* **Gemini 3.5 Pro**, the bigger and more capable version — but it didn't release it. Google said Pro was already being used inside the company and would roll out **'next month'**. Said in mid-May, that pointed to June.

By late June 2026, 'next month' had essentially arrived and gone, and Gemini 3.5 Pro still wasn't something the public could use. It wasn't in the Gemini app, it wasn't in Google AI Studio (where developers test models), and it wasn't in the main, stable programming interface (the API). In short: announced, talked about, but not yet in your hands.

## About those '2 million tokens' you may have read

A lot of articles list impressive specs for Gemini 3.5 Pro — most often a **2-million-token context window** (roughly, how much text it can consider at once) and a **'Deep Think'** reasoning mode. It's worth knowing that these come from **reports and expectations**, not from Google's confirmed details for Pro. They might turn out to be right — but until Google publishes an official technical report (a 'model card'), they're best treated as educated guesses. For comparison, the Flash model that *is* out has a context of about 1 million tokens, according to Google's own materials.

## Why the wait is normal

Here's the reassuring part: a bigger model arriving after a smaller one is completely normal. The larger and more capable a model is, the more testing, safety work and behind-the-scenes engineering it takes to get it ready for millions of people. Releasing the fast, cheap model first — so most users get an upgrade quickly — and holding the heavyweight back to polish it is a sensible plan, not a red flag. The only thing the delay really tells us is that the 'next month' estimate was a bit optimistic, which is common when a date is given from a stage.

> **Note:** **The honest bottom line:** Gemini 3.5 Pro is announced, not available. If you want to use Gemini today, use **Gemini 3.5 Flash** — it's out, it's fast, and it's the default in the app. Wait for Google's official model card before believing any specific specs about Pro, or making plans that depend on it.

**What should you do in the meantime?** If you're a everyday user, you're already getting Flash in the Gemini app and in Search — no action needed. If you're a developer or business deciding what to build on, Flash is the available, documented option; treat Pro as 'coming, eventually' rather than something you can schedule around. When Pro actually launches — with a real release, a model card and benchmark numbers — that's the moment to compare it properly. Good tech is worth reviewing when it's actually out, and this part isn't yet.

## Key takeaways

- Google makes the Gemini AI models. At its I/O event on 19 May 2026 it launched a fast model, Gemini 3.5 Flash, and announced a more powerful one, Gemini 3.5 Pro.
- Pro was announced but not released — Google said it was being used internally and would arrive 'next month'.
- By late June 2026, Pro still wasn't available in the Gemini app, Google AI Studio or the main API. Flash is the 3.5 model you can use.
- The '2-million-token context' and 'Deep Think' features you may have read about are reports, not confirmed by Google.
- Big AI models often arrive after their smaller versions — it's normal, and not a sign something is wrong.

## FAQ

### Can I use Gemini 3.5 Pro right now?
Not as of late June 2026. Google announced it at I/O on 19 May but hadn't released it — it's not in the Gemini app, Google AI Studio or the main API. The version you can use is Gemini 3.5 Flash, which launched on 19 May.

### Didn't Google promise it in June?
Google said Pro was being used internally and would roll out 'next month', which it said in mid-May — pointing to June. By late June it still hadn't launched publicly. It was a rough estimate, not a firm date, and it slipped.

### Is it true that Gemini 3.5 Pro has a 2-million-token memory?
That's a report, not a confirmed fact. The 2-million-token context and 'Deep Think' mode have been described in tech coverage but not confirmed by Google for 3.5 Pro. Wait for Google's official model card to know for sure.

### Should I be worried that it's late?
No. Bigger AI models usually come out after their smaller versions because they need more testing and safety work. Releasing Flash first and polishing Pro is normal. The delay just means the 'next month' estimate was optimistic.

### What's the best Gemini I can use today?
Gemini 3.5 Flash — it launched on 19 May 2026, it's the default in the Gemini app and in Search's AI Mode, and developers can use it via the Gemini API. Gemini 3.5 Pro wasn't available yet as of late June.
