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

A demo shows Gemini 4 Argon turning the flying Tesla Roadster into a Subway Surfers-style mini game.

A post claims Jio 5G plan users in India will get free access to the newly launched Gemini 4 Argon.

Gemini 4 Argon was initially limited to Ultra and paid API billing in AI Studio, and is now available to Pro users, including free-trial Pro accounts.

The author expects Gemini 4 Flash to keep 3.6-to-3.8 pricing and speed while getting much smarter, citing Argon's strength as evidence Google is preparing something big.

A Japanese user says Gemini 4 Argon's overall checking ability surpasses Claude Opus 5.5 and ChatGPT Sol 6.1, catching issues other models miss.

The post says Gemini 4 Argon is now usable in Google AI Studio for AI Pro subscribers including one-month trials, with 1M context, a March 2026 cutoff and $2/$10 per 1M token API pricing until Nov 30.

DeepMind's four Gemini 4 Argon agents beat the Ender Dragon end-to-end, but it was a single Easy-difficulty run with 605 deaths and no success-rate data, so the author doubts it proves real reliability.

Gemini 4 Argon is live for Pro subscribers, but free student Pro, Pixel bundles, Jio plans, old Antigravity IDE and Ultra for Business are excluded.

Someone used Gemini 4 Argon to build a playable Subway Surfers-style game themed around Tesla's flying car, with a demo video and link.

Google wiped Antigravity usage limits mid-cycle for the first time, resetting quotas on Gemini 4 Argon and existing Gemini models.

Gemini 4 Argon is reportedly live in AI Studio for both Pro free-trial and paid Pro users, no active paid subscription required.

Gemini 4 Argon is now available in AI Studio at an introductory $2 input / $10 output per 1M tokens through Nov 30, doubling to $4/$20 afterward.
