Engineering work that lasts for daysCarbon scores 59 on Artificial Analysis Intelligence Index v5.0. Google highlights improvements in coding, tool use and sustained task execution, saying internal teams have used it for days to diagnose and patch problems in large codebases. Google also highlights evaluations of vulnerability discovery, validation and remediation, with cybersecurity a central use case for the initial release.

Introductory prices halvedThe introductory price is $2 per million input tokens and $10 per million output tokens. A 95% cached-input discount puts cached input at $0.10 per million tokens; regular input and output prices will be $4 and $20 after the introductory period. Google also reports zero successful attacks in the evaluated Gray Swan indirect prompt-injection benchmark.
