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

A user shared that Gemini 4 Argon now shows up in their Gemini model picker under "solve complex problems," suggesting the rollout is widening.

A Chinese post complains that Gemini 4 Argon still isn't out days after its announcement and that further delay will leave it behind.

A Turkish user says Haiku 5.5 is coming tonight and complains that people were waiting for Gemini Argon instead.

A leak claims Gemini 4 Argon is rolling out today, has appeared in Google Cloud, and comes with Antigravity improvements as older Claude-powered workflows are replaced.

Google named Argon again with deep reasoning, software engineering, 1M output and $2/$10 intro pricing, but official access is still Fairwind and most paying Pro and Ultra users can't select it.

A short 'unpopular opinion' post argues that Gemini 4 Argon is better than Opus 5.5, without offering any test data.

A user posts that Gemini 4 Argon will not launch today, suggesting the release is still pending with no official confirmation.

On September 30, Google introduced Gemini 4 Argon, calling it its strongest model for complex tasks, with access first for cybersecurity partners and a public beta to follow.

The poster says there are reports that Gemini 4 Argon could launch that day and asks others what they expect from the model.

A user complains that Gemini 4 Argon is rumored to already be in Antigravity or Gemini, but Google has neither confirmed it nor given a release date.

A leaker says Gemini 4 Argon will definitely launch this week, that most access screenshots circulating are fake, and that the few real ones come from early testers breaking NDAs.

The poster clarifies that Argon appeared in an edu account's model picker but identified itself as Gemini 3 Pro, suggesting a UI bug, though they still expect the model to ship soon.
