Is Gemini 3.5 Pro Out Yet? (July 31, 2026 Status)
The Short Answer
No — Gemini 3.5 Pro is still not generally available as of July 31, 2026. Google has missed multiple target dates (including a rumored July 17 launch) after reportedly rebuilding the model. The Pro-tier model you can use today is Gemini 3.1 Pro ($2/$12); the newest Google model that actually shipped is Gemini 3.6 Flash (July 21).
The Timeline of Delays
- June 2026: Google pushed 3.5 Pro’s GA to “July 2026,” citing quality refinements after enterprise testing.
- ~July 13: Reports of a targeted July 17 launch — never confirmed by Google.
- ~July 17: Still no model. DeepMind reportedly scrapped the original build after engineers found structural issues and did a full rebuild.
- July 31: Still not out. Google’s line: “using it internally… will roll out to everyone next month.”
Two-plus missed windows and a full rebuild is why 3.5 Pro remains a “coming-soon” flagship, not something you can call from the API today.
What Google Actually Shipped
| Model | Status | Price ($/MTok) |
|---|---|---|
| Gemini 3.6 Flash | GA Jul 21 (AI Mode default) | $1.50 / $7.50 |
| Gemini 3.5 Flash-Lite | GA Jul 21 | $0.30 / $2.50 |
| Gemini 3.1 Pro | GA (current Pro) | $2 / $12 |
| Gemini 3.5 Pro | NOT out | announced ~$15 / $60 |
Gemini 3.6 Flash is the notable win — it’s now the AI Mode default and uses up to 65% fewer output tokens, cutting real costs even at the same sticker price.
What To Use Right Now
- Google flagship today → Gemini 3.1 Pro ($2/$12).
- Cheap, high-volume → Gemini 3.6 Flash ($1.50/$7.50).
- Top coding accuracy → Claude Opus 5 (96% SWE-bench Verified) or GPT-5.6 Sol.
The practical lesson: build model-agnostic. A launch slipping in Mountain View shouldn’t block your product.
