Gemini 4 Carbon is now available
Carbon launches at Argon’s introductory API price: $2 per million input tokens and $10 per million output tokens.
Google positions it for complex coding, extended agent workflows and scientific research, while recommending Argon for most software engineering and knowledge work. Carbon uses more tokens to reason and verify, so equal token pricing does not guarantee equal task costs. Access is open to paying API customers and rolling out to Google AI Ultra subscribers across Antigravity, the Gemini app and AI Mode in Search. Google is also previewing Antigravity’s `/swarm` feature, which coordinates multiple agents from a single prompt.
