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

A user complains that Gemini Pro's 5TB storage and YouTube Premium Lite go unused and asks for a pure AI plan that converts those perks into Gemini 4 Argon quota.

A Japanese post breaks down the ¥2,900/month Google AI Pro plan, covering YouTube Premium Lite, 5TB storage, a $10 monthly Gemini API credit and unlimited Gemini 4 Argon, and recommends a relay of Argon for planning, 3.8 Flash for execution and Opus 5.5 for finishing.

A user notes that Gemini 4 Argon in Antigravity is open only to paid Pro subscribers, excluding student Pro, Pixel users and India's Jio, and guesses it sits near Astra and Fable level.

Chinese users report that after Gemini 4 Argon launched, Gemini membership accounts on Xianyu rose sharply in price, with the cheap listings largely gone.

The author used Opus 5.5 through Google Antigravity and burned about 70% of the weekly quota in roughly 8 turns, and does not recommend the setup after also testing Gemini 4.

A paid Google Pro user found that Gemini normal, Opus and Argon quotas are independent, estimating a weekly limit of about $10 and calling it too little.

A post with an image captioned "Gemini 4 Argon btw…" shows the model's output, suggesting its performance is worth attention.

The author lists 10 entry points for Gemini 4 Argon, including the Gemini app, AI Studio, Antigravity, Cursor and OpenRouter, and notes Google has begun a gradual rollout to Pro users with a separate weekly Argon quota.

Gemini 4 Argon is rolling out in Antigravity to paid Google AI Pro subscribers with a separate weekly Argon quota on top of the existing 3.8 Flash bucket.

A user confirms that low-cost Jio Pro accounts bought on Xianyu cannot use Gemini 4 Argon in Antigravity, and that only the official $19.99 monthly Pro plan works.

Someone had Claude call Gemini 4 Argon at the High setting and evaluate its ability, and Claude praised Argon's performance, which the poster calls recognition from a top model.

A leak says Argon gets its own weekly quota in Antigravity, capacity was expanded after heavy demand, and the poster has already been using it heavily.
