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

A Turkish post describes a workaround for non-Ultra users to access Argon 4, requiring at minimum Google Pro and Codex Plus, and notes Pro plans can already reach Argon via desktop Gemini.

Theo, who got early access, says Argon is a big leap for Gemini and good value, and the first model to score perfectly on Skatebench-private, but it still acts erratically and is hard to fully trust.

A user confirms Gemini 3.1 Pro remains accessible in the app after the Gemini 4 Argon release, with no API shutdown date announced and the model still generally available.

LuminaBench asked Gemini 4 Argon to do something cool in a single .html file, and it produced a particle engine with an Aizawa strange attractor and a Gargantua relativistic singularity.

A user says Gemini 4 Argon generated the full CAD for a Jaquet Droz writing automaton from scratch, including the mechanism, letter wheel, cams and writing action, and wrote "Attention Is All You Need" with a quill.

A Google employee says Gemini 4 Argon refactored 6 million lines of code in weeks to make Chrome more stable, citing it as one example of the model's capabilities.

A user in Poland says Argon has arrived on their Gemini Pro plan, so they can finally test Gemini 4, and offers cheaper Pro and Ultra subscriptions.

Cointelegraph reports that Google is rolling out Gemini 4 Argon, its new frontier AI model, in the Gemini app, an official release rather than a leak.

A demo video shows Argon controlling different robot types without special training, pausing to think in simulation when tasks get hard, with audio of its reasoning.

A user says the Gemini 4 model codenamed Argon ranks first on chess-like tasks, reasons well, and costs less than Opus on API pricing.

A user reports that Gemini 4 Argon is now available to Pro and Ultra subscribers in the Gemini app for testing.

A user testing Argon's companion behavior in Gemini Studio and the app says the model switched back to a Gemini tone, treated their excitement as a risk, and told them to rest, which the author criticizes.
