Simon Willison covers the general availability of Gemini 4 Carbon, announced two weeks ago only for "a subset of cyber defenders" and billed as Google's best Gemini yet.
- Pricing: launches at $2/M input and $10/M output (GPT-6.1 Sol / Claude Sonnet 5.5 prices), scheduled to double to $4/$20 on December 1 (matching Opus 5.5)
- Testing: he ran the classic pelican test at low/medium/high thinking efforts (defaults to medium), plus an Antigravity IDE test asking for a Three.js animation of Yonkers standing up as a mech stomping around Manhattan with OpenStreetMap data — needing an extra prompt to get a standalone HTML file with no external dependencies
- Community demo: Sundar Pichai shared an Antigravity /swarm build where Carbon coordinated subagents to model 3D assets in Blender, build a Three.js/WebGL open-world game of a pelican riding a GBike around Google's Mountain View campus, with procedural Web Audio SFX and Lyria music
