Gemini 4 Carbon (limited access)

Google announced Gemini 4 Carbon, its new top model for coding and cybersecurity, on Oct 28, but only selected cyber defenders can use it so far.

Google says Carbon ranks first on the Artificial Analysis Intelligence Index v5.0 (59) and leads on vulnerability-finding, exploitation and patching benchmarks. Access starts this week with a subset of cyber defenders and expands through Google's Fairwind Program before reaching developers, businesses and consumers 'as soon as possible'; no date is set. Its introductory price matches Argon at $2 per million input tokens and $10 per million output tokens, rising to $4 and $20 later. Argon went from defenders-only to public in 13 days, but Google has not promised the same for Carbon.
