Is Gemini 3.5 Pro released yet?

No. As of late July 2026, Gemini 3.5 Pro is still not generally available. It was targeted for June, then July (including a widely-cited July 17 date that passed), and Google's pages still say '3.5 Pro coming soon.' Only limited enterprise/partner access exists.

Why is Gemini 3.5 Pro delayed?

Reports point to Google refining quality — hallucination rates, real-world reliability, and coding benchmarks — before a broad launch. There's also speculation Google may lean on the Flash line (3.6 Flash shipped July 21) rather than rush Pro.

What should I use instead of Gemini 3.5 Pro?

Use Gemini 3.6 Flash, Google's new 'workhorse' model (shipped July 21, 2026) with near-Pro coding at Flash-tier price. For frontier-level work, Claude Opus 5 or GPT-5.6 Sol are the strongest generally-available options right now.

Quick Answer

Is Gemini 3.5 Pro Out Yet? (Aug 2026 Delay Update)

Published: July 30, 2026

The Short Answer

No — Gemini 3.5 Pro is still not generally available as of late July 2026. It has slipped from June to July (a much-cited July 17 target came and went), and Google’s official pages still read “3.5 Pro coming soon.” Only a limited set of enterprise/partner customers have access.

The Timeline

Date	Status
Originally projected	June 2026
Slipped to	July 2026
July 17 target	Passed, no public launch
May 19, 2026	Gemini 3.5 Flash shipped (GA)
July 21, 2026	Gemini 3.6 Flash shipped — Google’s new “workhorse”
Late July 2026	3.5 Pro still “coming soon,” no official date

Why It’s Delayed

Reporting attributes the holdup to Google taking extra time to refine the model — specifically hallucination rates, real-world reliability, and coding benchmarks — before exposing it broadly. There’s also a strategic thread: with Gemini 3.6 Flash landing as the new workhorse, some observers think Google may deprioritize a rushed 3.5 Pro in favor of the fast, cheap Flash line. Reports suggest a launch no later than August, but Google hasn’t committed.

What To Use Right Now

Google-native, cheap, strong coding → Gemini 3.6 Flash. Shipped July 21, it delivers near-Pro coding at Flash-tier cost with big token-efficiency gains (up to 65% fewer tokens on long engineering tasks) and ~83% on OSWorld-Verified.
Frontier-level work → Claude Opus 5 ($5/$25) or GPT-5.6 Sol ($5/$30). Both are GA and lead the coding/agentic benchmarks today.
Cheap value flagship → Grok 4.5 ($2/$6).

Should You Wait?

No. If you need Pro-tier Gemini capability today, use Gemini 3.6 Flash and re-evaluate when 3.5 Pro actually ships — Google has repeatedly missed its own targets on this one. Build now on a GA model rather than blocking on a “coming soon” page.
