GoogleCorrection: Gemini 3.5 Pro has not been released is framed by spectrum bands and long-context tracks.

On July 1, 2026, this page published a full review of a model called Gemini 3.5 Pro: a claimed June 30, 2026 launch, a 2,000,000-token context window, tiered pricing at $2.50/$15 per million tokens, and a set of benchmark scores including a claimed 95.5% on GPQA Diamond. A routine fact-check on July 8, 2026 found none of it holds up. Gemini 3.5 Pro has not launched.

Two checks settle it. Google's current Gemini model guide and pricing page list callable models such as Gemini 3.6 Flash and Gemini 3.5 Flash-Lite, but no Gemini 3.5 Pro endpoint or rate card. Google DeepMind's own model hub labels “3.5 Pro coming soon.” The two external sources originally cited for this page's launch and benchmark claims still do not resolve.

Claimed record versus the official record

This correction rests on records a reader can check, not on a replacement estimate. The table preserves the withdrawn claims so the error remains auditable, then shows what Google's own product and pricing pages contained when benchr checked them on July 29, 2026.

“Not listed” is a time-bounded finding, not proof that Google will never release the name. Until a callable model, model card, and rate card exist, this URL functions as a correction notice rather than a current product review.

This wasn't a real launch with an outdated number attached to it. It was a page describing a product that, as of this correction, Google has not shipped. benchr isn't going to guess at when it might arrive. Some third-party reports have floated dates, but none of them trace back to an official Google source, so none of them are printed here. If Gemini 3.5 Pro ships with verified official pricing and benchmarks, benchr will publish a new review built from that information, not a rewrite of this one.

What's withdrawn: the original review text, its benchmark table, its pricing breakdown, and the Review and Offer structured data that described a rating and a price for a product that isn't on the market. None of that belongs on a page benchr expects readers to trust.

If you came here looking for Google's actual current flagship model, that's Gemini 3.1 Pro — reviewed with real, sourced pricing and benchmarks, still current as of this correction. Every other correction benchr has made, factual or stale, is logged at /corrections.

The site's whole premise is that every figure gets checked. Publishing figures for a model that didn't exist is the exact failure that premise exists to prevent, so this correction says so plainly instead of quietly editing the page.

Frequently asked

Did Google release Gemini 3.5 Pro?

No. As of July 29, 2026, Gemini 3.5 Pro has not shipped. Google DeepMind labels it “coming soon,” and Google's live API model and pricing pages publish no 3.5 Pro endpoint, price, or specification.

What was wrong with benchr's original page?

benchr published a review and a pricing page describing Gemini 3.5 Pro as though it had launched on June 30, 2026, complete with pricing and benchmark figures. None of it could be verified: the two external sources originally cited no longer resolve, and no official Google source confirms any of the claimed figures. The review and pricing figures have been withdrawn.

Where can I read about Google's current flagship model instead?

Gemini 3.1 Pro remains Google's available Pro-class model. Gemini 3.6 Flash and 3.5 Flash-Lite are newer Flash-tier releases, not a released Gemini 3.5 Pro.
