Report: Google’s Gemini 4 “Carbon” variant reportedly matches Anthropic Opus 5.5 on coding tasks
Business Insider reports that Google is testing several Gemini 4 variants (Argon, Barium, Carbon). Internal documents, screenshots, and chats say Carbon was deployed on Google’s internal coding platform Jetski and reportedly outperforms Argon on programming tasks, with one employee comparing it to Anthropic’s Opus 5.5; it’s unclear if Carbon will ship as an Argon update or a standalone model and the claims remain unverified.
