Google Unveils Gemini 4 Carbon: A Leap in Cybersecurity and Long-Horizon Coding, But Most Users Can't Access It Yet

Just two weeks after launching Gemini 4 Argon, Google has unveiled Gemini 4 Carbon, its latest frontier AI model focused on defensive cybersecurity, long-horizon coding, and complex agentic workflows. While Carbon tops the Artificial Analysis Intelligence Index and sets new standards in vulnerability discovery and prompt injection defense, it is currently locked behind a staged rollout via the Fairwind program. Here is an in-depth breakdown of its benchmark performance against Claude Opus 5.5 and GPT-6 Astra, its reliability trade-offs, and what developers need to know about API pricing and migration.

OpenAI Releases GPT-6.1 Terra: API Prices Halved, $0.05 Cached Input, and a Complete Selection Guide

OpenAI has officially launched GPT-6.1 Terra, a high-throughput mid-tier model that cuts standard API pricing by 50% compared to GPT-5.6 Terra and GPT-6.1 Sol. With input tokens at $1.00 per million, cached input dropping to $0.05, and execution speeds more than triple those of Astra and Sol, GPT-6.1 Terra reshapes the economics of visual understanding, computer use, and everyday agentic workflows.
