Google DeepMind launches Gemini 4 Carbon, top paid chat model on FreeLLMArena
Gemini 4 Carbon debuts with advanced cybersecurity performance and pricing of $2 per million input tokens.
Google DeepMind announced Gemini 4 Carbon on Oct 28, 2026 as its newest frontier model.
Carbon ranks #1 on the v5.0 Artificial Analysis Intelligence Index with a score of 59 and leads external benchmarks: 88.2% on SEC‑bench Pro, 54.8% on ExploitGym, and 71.0% on CWE‑bench.
The model builds on Gemini 4 Argon and shares the same safety stack, adding improvements in alignment, reduced misalignment alerts by almost 80%, and zero successful cheating on Terminal‑Bench 4.0.
