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

A two-line post speculates that Gemini 4 Pro is out and aimed at Opus and Astra, with no testing or evidence offered.

A user says Gemini 4 Argon was spotted in Google Cloud and some users already see it in the model selector.

Gemini Ultra users report that Gemini 4 Argon is starting to appear, with some saying Gemini 3.1 Pro is being silently routed to Argon.

Google's Playground page for creating and playing custom games appears to be live ahead of an announcement, though the poster says they are really waiting for Gemini 4 Argon.

A leak says Argon, reportedly Gemini 4 Pro, has appeared in Google Cloud, codes inside Antigravity, is the default model in the Antigravity CLI and contributed to a real coding commit, with launch possibly today.

Rumors say Gemini 4 Argon is starting to show for a few users in the Gemini app and Antigravity.

Several people shared screenshots showing Gemini 4 Argon inside a Google Cloud limited form, though most are still blocked by Fairwind, and the poster expects a release soon.

A user says Gemini 4 Argon is being rolled out and suggests Ultra subscribers check the Gemini web app to see if they have it.

A video described as a self-generated ferrofluid spike simulation with a parameter control panel carries a disclaimer that its origin is unconfirmed and it may be AI-generated.

Some say Argon is live in Antigravity, the CLI or Cloud, but nobody can confirm an official release, and one user says Google is riding the confusion to keep hype alive.

A tip says Gemini 4 Argon is rolling out while the cost-effective Gemini 3.6 and 3.7 Flash models are being removed, raising user concerns about higher costs.

A roundup post lists OpenAI's day 2 updates, nano banana 2.1, Mistral Large 4 and other releases, then wonders whether Gemini 4 Argon is next.
