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

A screenshot claiming to show Gemini 4 Pro benchmarks is circulating, and the poster admits the source is unreliable and that Google would not run a model at full load like that.

He says post-training still takes time and Gemini 4 Pro will eventually arrive, but the key question is whether Google can widen the gap between Pro and a stronger Flash enough to justify the Pro tier.

Shahbaztwt rounds up the latest rumors that Google's next model could match Fable and Astra, and says Google may have something big if that gap is real.

A leak claims Google's first Pro checkpoint is ready and being tested on Arena possibly disguised as gemini-3.8-flash, with leaked benchmarks putting it ahead of GPT-6 Astra and Fable 5.1.

The author compares Gemini 3.8 Flash and Gemini 4 Pro directly in Arena (listed under the 3.7 codename) and concludes that Gemini 4 Pro or Flash performs best.

A video compares outputs from Gemini 4 and Astra on the same prompt, and the author says the gap is getting hard to ignore.

A leak says Gemini 4 and the next Astra model will launch together next week, with Anthropic possibly shipping around the same time, seen as this summer's RSI results arriving at once.

A post says rumors have Gemini 4 Pro competing hard against Fable and Astra, and that Google may actually be making a real comeback this time.

A Korean user discovered that a Gemini subscription grants 1,000 Google Flow credits each month plus 50 per day, and also mentioned rumors that Gemini 4 Pro is very strong.

Shahbaztwt shared a screenshot of a Gemini 4 Pro benchmark, saying the first bar is not playing fair, without specifying which test it is.

A short reply to Google AI Studio says the user is waiting for Gemini 4 to be released before starting to build anything.
