Summary
Google’s Gemini 4 Carbon, its most capable model to date, arrived just one day after Anthropic’s Claude Fable 5.2, and this video looks past the leaderboards to see how it performs on real work. It covers what Carbon is: a longer-thinking model built on Gemini 4 Argon, announced October 28 and opened to AI Ultra subscribers and developers on November 10 through Google AI Studio, Android Studio and Anti-Gravity.
The walkthrough looks at community tests in 3D worlds and games, where Carbon impressed with scenes in Blender and Unity, a custom CUDA path tracer and agent-swarm builds in Anti-Gravity. Head-to-head, Claude Fable 5.2 still produced noticeably better graphical fidelity, while Carbon was far cheaper and faster. On the Artificial Analysis Intelligence Index, Carbon scores 60 against Fable 5.2’s 65.
Pricing gets close attention. Carbon’s introductory rate of $2 per million input tokens and $10 per million output tokens is set to double on December 1, and the model uses a very large number of output tokens. Long agentic builds can cost a fraction of Fable’s, but on subscription plans Anthropic’s offerings appear more generous. In real-world coding tests, Carbon scored 53.3% against Fable 5.2’s 70% and often overclaimed features that were broken. The video closes with guidance on when to choose Carbon and when Argon or another model is the better fit.
