Top News · 281 HN points

Gemini 4 Carbon is Google's frontier release for complex, multi-step agent workflows, following Gemini 4 Argon. Google says Carbon ranks #1 on CursorBench 4.0, Perplexity's WANDR, and Zapier's AutomationBench at more than 2× lower cost per task than the next-best external model.

Here's what changed:

• Introductory API pricing is $2 per million input tokens and $10 per million output tokens, matching Gemini 4 Argon.
• Paid-tier Gemini API access is available in Google AI Studio and Android Studio.
• Google AI Ultra subscribers can try Carbon in AI Studio, Google Antigravity, the Gemini app, and AI Mode in Search.
• Enterprises can use Gemini for business via API or its model dropdown, plus Google Antigravity or CodeMender.

One catch: Gemini 4 Carbon uses more tokens than Gemini 4 Argon for exploration, reasoning, and extended verification loops.

Try it: Use the paid-tier Gemini API in Google AI Studio or Android Studio. Also available via Vercel, Google DeepMind, Hacker News, explainx.ai
