> **Key:** **The one-liner:** Google made its fast model the default everywhere — and announced a flagship it hasn't actually released.

**What happened.** At **Google I/O on 19 May 2026**, Google launched **Gemini 3.5 Flash** and made it the default in the consumer Gemini app, **AI Mode in Search** and the **Vertex/Gemini API**.

**The claim.** Google positions Flash as **beating Gemini 3.1 Pro** on coding, agentic and multimodal benchmarks (a cited 76.2% on Terminal-Bench 2.1) — vendor/third-party figures, so attribute.

**The price.** Reported API pricing is **$1.50/M input, $9/M output** — about **3× the prior Gemini 3 Flash** (per reporting).

> **Note:** **The catch:** **Gemini 3.5 Pro** was announced but **not released** — Pichai said 'give us until next month', and as of 15 June it remained a limited Vertex preview (2M context, 'Deep Think'). Don't expect Pro yet.

## Key takeaways
