Gemini 4 Pro / Flash: benchmarks, hands-on tests and leaks

The author cites an unconfirmed leak that Gemini 4 Pro arrives in October and plans to add Antigravity 2.0, new models and voice content to the tutorial.

A leak account shares generation speed figures for Gemini 4 Pro in high effort mode, about 63.4 tok/s over roughly 7 minutes, and says more samples are coming.

TheShortBear says Gemini 4's leaked numbers would beat records if close to real, and that Anthropic now faces competition from all sides.

A leak claims Google is waiting for the right moment to launch Gemini 4 Pro, which reportedly lands between Opus 5.5 and GPT-6.1 Sol in performance while being faster and cheaper than both.

A user reports that an Arena entry named Gemini-3.8-Flash appears to route to Gemini 4.0 Pro, with a video demo.

A video tests GPT-6.1 Sol, GPT-6 Astra and Gemini 4 Pro on the same prompts, with the author saying Sol and Astra perform very similarly and Gemini 4 Pro joining as the value pick.

LuminaBench gives three models the same prompt to generate a 3D Colosseum, with Gemini 4 Pro on checkpoint 3, and the author says Astra and the new Sol feel very similar.

The poster jokes that the funniest thing today would be Google releasing a Gemini 4 that crushes every benchmark purely for the memes.

The poster questions whether Gemini 4 Pro will actually launch today and says the rumor mill will lose a lot of credibility if the leaks fall through.

The author posts a video showing a new Gemini 4 Pro checkpoint generating a side-view SVG of a BMW M4 CS.

A leak says a new Gemini 4 Pro checkpoint has landed in Arena and performs extremely well, and at this pace it would beat every current model on release.

quantian1 speculates that Gemini 4 Pro is very strong but Google is holding it back for now so it doesn't disrupt Anthropic's upcoming IPO valuation.
