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

A single HTML file with procedural Three.js renders a 7.75M-voxel scene with a pagoda, bridge, viaduct and steam train at 60fps for $2.48.

A Spanish-language video argues Gemini 4 lets non-specialist designers build 3D websites, undercutting agencies that charge around $50K.

Testing Gemini 4 Argon as it rolls out to all Antigravity users, the author found it refused all 100 black-box hacking labs but built a full 3D cathedral from a single image.

Rumor says Gemini Carbon, a new Gemini 4 model built on Argon, is in early access for Google teams and partners, targeting long-horizon coding, agent workflows and 3D generation at 2–4x slower speed.

The author is developing a Three.js skill for Gemini 4 Argon and used it to generate an interactive 3D web simulation of the 1949 MONIAC water-powered economic computer plus a demo video.

A roundup of upcoming model releases says Gemini 4 Carbon has shown up on Arena with stronger 3D capability than Argon, alongside Claude Fable 5.5, Qwen4 and GPT-6.1 Terra.

In Antigravity, a single text prompt has Gemini 4 Argon model and rig assets in Blender, batch import them into Unity, and generate editor tools for wave physics, shaders and lighting.

AI Studio Build works well with Gemini 4 Argon and adds one-click UI chips for making games, building Three.js 3D scenes and using DeepMind's science skills.

A developer demos an endless 3D European street made with Gemini 4 Argon that starts as a hand-drawn ink sketch and blooms into watercolor as you walk or hover.

A video shows Gemini 4 Argon inside Antigravity generating a single-file Three.js test in one shot, highlighting its front-end code generation.

The author used Blender for 3D models and Antigravity with the Argon 4 model to build a flight simulator with realistic physics and challenging landings, sharing a video for ratings.

The same Blender MCP task, modeling an 1800s artisanal pistol, is priced across models: Gemini 4 Argon at $1.03, Claude Opus 5.5 at $1.62, GPT-6 Astra at $2.58 and Kimi K3 at $0.75.
