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

Google confirmed Gemini 4 Argon is rolling out to an initial cohort of cyber defenders through its Fairwind Program, with feedback gathered before release to developers, enterprises and consumers.

Sundar Pichai says he shared Gemini 4 Argon early because of outside discussion, posting benchmark results and noting Google teams already use it widely for coding and quantum computing.

A report says Google employees are raising concerns about Gemini 4's performance in coding and other key tasks, and that the model does less well on real-world work despite strong benchmark results.

Bloomberg reports that some Google employees with access to Gemini 4 say its strong benchmarks don't fully carry over to real coding and front-end design, and that the model is very large and costly to run; Google denies it is behind.

A leak says Gemini 4 Argon is state of the art, was tested with the US government and cybersecurity testers before release, and has been used to optimize global data centers and port parts of Fuchsia to Rust.

A clip said to be generated by Gemini 4 Pro shows an espresso machine with a glass chamber and glowing copper coils, plus a robot arm dropping a sugar cube, with the poster noting the footage's origin is unconfirmed.

A user spotted what looks like an official Gemini 4 Pro entry in the Respan router and expects a release around the second week of October.

A screenshot shows Gemini 4 Pro listed in the Respan router's model pool, and the poster guesses it may launch officially in October.

A leak says DeepMind spent seven months on Gemini 4 Pro, but tests suggest it may be weaker than GPT-6 Astra and Opus and may not take the top spot.

The poster asks whether Gemini 4 Pro living up to rumors would change views on Google stock, noting Google's buzz has faded since Antigravity and Gemini 3.

Running the same test with GPT-6 Astra xhigh in Codex, the author says Gemini 4 Pro is clearly better on details like bee shape and metal texture, and mentions seeing outputs from a new G4P checkpoint.

A post with an image that appears to show the words Gemini 4 Pro asks whether Google will release it soon, with no hands-on test or official source.
