Google launched Carbon on 28 October only for a group of cyber defenders through its Fairwind program. It is now available in Google AI Studio and Gemini for business to all paying developers and enterprises, and is rolling out to Google AI Ultra subscribers in the Gemini app, AI Mode in Search and Antigravity. The introductory price matches Argon's: $2 per million input tokens and $10 per million output tokens. According to The Verge, prices double at the end of November when the introductory period ends, and it is not clear if or when Carbon will reach cheaper tiers or free users.
Google pitches Carbon for the hardest tasks: multi-step coding and debugging and open-ended scientific research, using more tokens than Argon, which it says remains the right choice for most work. According to the company, Carbon ranks first on CursorBench 4.0, Perplexity's WANDR and Zapier's AutomationBench at more than twice lower cost per task than the next external model. On a new benchmark it built with Artificial Analysis, Multimodal Knowledge Agent, it ranks second.
/swarm, in preview in Antigravity, splits work among agents: Carbon takes the roles of design, coordination and auditing, alongside faster, lighter models running in isolated workspaces, with agents that test every change. The performance figures are Google's, and The Verge notes that companies tend to highlight the results that suit them.
