Google Gemini 4 Carbon is now publicly available - and it undercuts Claude Fable 5.2 and Opus 5.5 on API price

Key Points:

• Google has made its advanced AI model, Gemini 4 Carbon, generally available to most users, including Google AI Ultra subscribers and businesses, following a limited rollout to cybersecurity defenders in its Fairwind program.
• Carbon is accessible via the Gemini app, AI Mode in Search, Antigravity, and the paid Gemini API, with U.S. subscription prices ranging from $99.99 to $199.99 monthly, and token pricing starting at $2 per million uncached input tokens.
• The model supports multimodal inputs (text, images, speech, video) with text output, and Google emphasizes Carbon’s cost-effectiveness and competitive performance on benchmarks like Zapier AutomationBench, although some performance claims remain unverified publicly.
• Carbon excels in tasks such as software engineering and cybersecurity, with specialized cyber versions available through Fairwind, but in some benchmarks, competitor models like Anthropic’s Fable 5.2 lead in accuracy and efficiency.
• Google encourages enterprises to pilot Carbon alongside existing models to evaluate cost, performance, and workflow impact before the promotional pricing ends, highlighting its potential role in complex AI agent orchestration and specialized business applications.
