Google Releases Gemini 4 Carbon for Complex Coding and Research

At a glance

Google has released Gemini 4 Carbon to developers, businesses, scientists, and general users. It targets complex multi-step coding, debugging, and open-ended research that need deep reasoning and long verification.

Key points

1. 1

   API pricing is $2 per million input tokens and $10 per million output tokens, the same as Gemini 4 Argon.

2. 2

   Carbon uses more tokens than Argon to explore multiple solutions and check its results.

3. 3

   It ranked first on CursorBench 4.0, WANDR, and AutomationBench, and its cost per task was less than half that of the next-best outside model.

4. 4

   The /swarm preview in Google Antigravity splits one request among several agents.

Why it matters

It shows that more capable AI models are increasingly taking on complex work without being prohibitively expensive.
