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

An account claims Google's next model after Argon has leaked under the name Gemini 4 Uranium, without citing any source or details.

A leak says Google is internally hyping another model codenamed Carbon alongside Argon, which the poster calls a smokescreen.

Andrew Ng's weekly Batch letter says agents making thousands of searches a day will drive data center demand, and also lists GPT-6.1 Sol, Gemini 4 Argon and more.

Documents seen by Business Insider show Google staff testing a new model codenamed Carbon as Argon nears public release, describing it as feeling exactly like Opus 5.5.

A post lists rumored Argon details: Ultra subscribers get it first, about $4 input and $20 output per million tokens, a 1M context window, and early tests near Opus 5.5.

All models in the Gemini app and web now offer Low, Medium and High reasoning effort, and Logan said Gemini 4 Argon will not be cancelled.

Citing Business Insider, LiveSquawk says Google is about to release a new AI model while employees test another, stronger version, pointing to the Gemini 4 Argon, Barium and Carbon line.

Business Insider reports that Google is pushing new versions of its Gemini 4 models to employees before a public launch, with the latest codenamed Carbon drawing positive staff feedback.

Business Insider, citing sources, says Google is preparing to publicly roll out its new Gemini 4 model, internally known as Argon, sending GOOGL shares moving.

A roundup of Argon's 1M-token output, $2/$10 launch pricing, Fairwind early access, the disputed 77.9% DeepSWE score and a claimed 2.7x speedup from a 32,000-line Rust rewrite.

A prediction post names Gemini Argon 4, reportedly Gemini 4 Pro, alongside Opus 7 and Kimi K5 as models arriving in 2027.

A user says Google keeps hyping Gemini 4 Argon but it still can't be used, and claims it will only be available on the Ultra plan.
