## Why it matters

Google CEO's launch post, the most viewed (~677K views on launch day); gives the AA score, the three cyber scores and the staged rollout.

## Summary

Pichai introduces Carbon two weeks after Argon ('I did say we'd be releasing our models periodically'), cites #1 on AA Intelligence Index v5 at 59, SEC-bench Pro 88.2%, ExploitGym 54.8%, CWE-bench 71.0%, and says trusted cyber defenders get it this week, then Fairwind partners, ahead of wider availability 'soon'.

> 
> Following Argon's release just two weeks ago, Carbon shows the pace at which we’re pushing the frontier, it ranks #1 on the recently updated v5.0 of @ArtificialAnlys Intelligence Index at 59. It also leads across key cybersecurity evaluations scoring 88.2% on SEC-bench Pro for finding vulnerabilities, 54.8% on ExploitGym for exploitation, and 71.0% on CWE-bench for patching.
> 
> We’re seeing significant improvements in long-horizon tasks even compared to Argon, and we’ve strengthened frontier safeguards.
> 
> As we did with Argon, we’re going to roll it out gradually + responsibly. Some trusted cyber defenders will get access starting this week. We'll be expanding it to more partners through our Fairwind Program, ahead of wider availability soon, so hang tight!
