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

bindureddy says Google is squandering its lead again, with Gemini 4 Argon still not widely available, and calls for a GA release soon.

A leak says Gemini 4 may launch today but only for Ultra users, and the poster asks whether the ARGON codename is a Pro or Flash model.

Gemini 4 Argon is rumored to launch today with Ultra subscribers first, API access alongside, a 1M context window, and early tests near Opus 5.5/Astra level.

A rumor says Gemini 4 Argon launches today with Ultra access first, API availability around the same time, a 1M context window, and $4 input / $20 output pricing.

Haleeeemahh says in a video that the claim 'Google has no models worth using right now' will change once Gemini 4 Argon drops today.

A comparison chart of US and Chinese model release schedules places Gemini 4 Argon (9/30) alongside GPT-6.1 Sol and Claude Haiku 5.5, with a call for domestic models to catch up.

According to @lyraxana, whose leaks have been accurate, Gemini 4 Argon launches today but only for Ultra subscribers and the API, leaving Pro users waiting.

Leaks say Gemini 4 Argon may launch today or tomorrow, and some Google Cloud users can already see an entry point.

A poster says Google's Antigravity platform is gradually rolling out Gemini 4, with an attached image that appears to be a screenshot of the interface.

A leak claims Argon is already in Google Cloud and may launch today, targeting frontier-level coding, knowledge work, cybersecurity and creative writing, with paid API users and Ultra subscribers getting it first.

A post cites a Gemini 4 Argon report in which an agent migrated the 800,000-line Fuchsia Zircon microkernel from C++ to Rust and rewrote 32,000 lines of libgav1 SIMD, achieving bit-identical output and 2.7x better performance.

Someone spotted a model ID "gemini-4-argon-cyber-permissive" on Vertex AI and believes Google is preparing broader access for Argon.
