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

Someone deployed Clockwork Colossus, a game generated by Gemini 4 Argon, to Vercel with a link that opens directly for play.

A user asks whether Gemini 4 Argon is actually cheaper than Opus 5.5 and GPT-6 Astra, or whether it is just hype.

The free tier is limited to Flash-Lite, AI Pro at 2,900 yen unlocks Gemini 4 Argon, and Ultra 5x/20x offer 5x and 20x the usage.

A Chinese user says a few game prototypes and about twenty rounds of interactive creation used up their Pro quota, questioning why Google's Pro tier is so stingy.

A screenshot shows Argon stressing that its answers aren't mechanical, prompting users to joke that the AI forgot it is itself an AI.

The head of Google's Demo Lab announced the Gemini 4 Argon launch and showed off a batch of official demos, including a 3D Rubik's cube built with three.js.

A developer with early access says Argon shows clear gains in 3D, coding and frontend motion, supports up to 1 million output tokens, and needs proper design skills to shine.

A post claims Argon cut T-gates by 94.5% on Cobble-Rz, with 48.8% fewer remaining gates than tzap -O3, proved core theorems in Lean 4, statevector-verified the circuits, opened upstream PRs, all for about $10.

Given the same prompt to build a voxel kingdom, Gemini 4 Argon produced nine landscape views, four weather/day-night states, a drawbridge and fireworks, while GPT-6.1 Sol produced only five views and two day-night states but a more comfortable distant view.

A user shares a very hard integral problem generated by Gemini 4 Argon that is said to be solvable with high school knowledge, with an image showing the problem.

A developer used Gemini 4 Argon to generate a 174,000-face carriage model from a single reference image without Blender, including opening doors, wheel physics and suspension.

A post says Argon completed a Video-to-Sim-to-Real pipeline: watching a human play cornhole, computing whole-body joint trajectories, generating simulation code, and sinking seven straight shots on Apptronik's Apollo.
