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

A user says Gemini 4 Argon is free and shares a v0.app link, inviting people to try it and share their experience.

A user says Google Argon (said to be Gemini 4 Pro) is included in the $20 Pro plan and plans to try it for a month after their Claude Code subscription expires, though they worry its usage limits won't match Opus.

LuminaBench tested Gemini 4 Argon on the same prompt to generate a 3D seaplane on water and says it produced the best result among the models tested.

A short post mentions using Gemini 4 Argon for vision tasks without giving any test details.

The author says Gemini 4 Argon handled modeling, materials, animation and cameras inside Mixar, an AI-native Blender fork, producing a 4K render of real 3D geometry without any manual input.

A user says Gemini 4 Argon is now available to Pro users in the Gemini app, though not yet in Antigravity, and is testing it.

A Japanese user who tried Gemini 4 Argon in the morning found the Pro plan can't access it in Antigravity, suggesting Argon's coding workflows remain locked to Ultra.

A user argues Argon may not be the strongest model, but at about $27.75 a month for the Ultra 5x plan, pairing it with Hermes gives a low-cost frontier-model agent.

GitHub announced that Gemini 4 Argon is now generally available in Copilot for complex coding and agentic workflows, and it beat previous Gemini models on coding benchmarks in early testing.

The developer handed his Kudümzen app to Gemini 4.0, which finished the iOS version, fixed music theory errors, rebuilt the audio engine, and wrote and built the Android version from scratch in about 7-8 minutes.

A tester who ran Gemini 4 Argon on tasks like a rocket launch says detail is lost as the flight goes on and the final shot is just a black silhouette, making it less polished than Opus 5.5.

A post says Gemini 4 Argon is available on xplabs.ai, claiming it beats Astra and Fable, costs 500% less, and supports 1M output tokens, though the source is not official.
