Google has made Gemini 4 Carbon available to the public, removing the previous restriction that limited access to a specific subset of cyber defenders. The model launches at $2 per million input tokens and $10 per million output tokens, with prices scheduled to double to $4 and $20 respectively on 1st December. Simon Willison tested the system using three different thinking effort levels to generate images of pelicans, noting that the high-effort output produced a detailed scene featuring a monocle and a bicycle. He also ran a complex coding prompt in Google Antigravity IDE to create a standalone HTML animation of a mech stomping through New York boroughs.
The main significance lies in the shift from restricted beta access to a broad commercial launch, establishing a clear pricing trajectory for Google’s most advanced model. The demonstration highlights the tool’s capability to handle multi-step creative tasks, from generating 3D assets to compiling browser games without external dependencies.
* Pricing doubles to match Opus 5.5 levels on 1st December.
* High thinking effort produces detailed visual descriptions.
* Antigravity IDE supports complex autonomous coding workflows.
