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

A short post argues that the release of Gemini 4 Argon will be a landmark turning point for Google, comparable to Opus 5.5.

A post with an image speculates that Gemini 4 Argon could launch next Monday, an unconfirmed timing rumor.

A one-line post laments that Google appears to have killed Gemini 4 Argon, reflecting community concern over its fate.

A Japanese post says Gemini taught that flashy features and sweet words mean nothing without substance, and ends by noting Gemini 4 Argon has yet to arrive.

A post with an image claims Google's next model after Gemini 4 Argon carries the element-based codename Ytterbium.

A poster claims Google employees deleted tweets about RSI during the Argon blog launch, and mentions an internal codename Carbon positioned against Opus 5.5.

A parody post in Sundar's voice says it is now company policy to use only Argon, and to tell reporters the truth if asked which model they use.

An unverified claim says Google called Gemini 4 Argon so bad that it already uses a new in-house model, Carbon, said to match Opus 5.5.

A poster notes a new Gemini 4 checkpoint called Carbon on Arena, after Argon and Barium checkpoints had already gone live, and wonders what DeepMind is planning.

Business Insider reports employees are testing a Gemini 4 model codenamed Carbon that one person says feels comparable to Opus 5.5 for coding, though it is unclear whether it is a newer Argon checkpoint.

According to Business Insider, a new Carbon checkpoint appeared in Google's internal coding platform Jetski, with early claims that it can rival Claude Opus 5.5.

A user shares a benchmark screen from Google's event showing Gemini 4 Argon beating Opus 5.5, and notes a new Gemini 4 version called Carbon matches it.
