Google's follow-on to Gemini 4 Argon (launched two weeks ago) ranks #1 on Artificial Analysis Intelligence Index v5.0 at 59 and leads the cybersecurity benchmarks it reports: SEC-bench Pro 88.2% finding vulnerabilities, ExploitGym 54.8% validating them, CWE-bench 71.0% patching them; it also reports 0.0% success for indirect prompt-injection attacks and cheating on Terminal-Bench 4.0 cut to 0.0%. Priced at Argon's introductory $2 / $10 per million input/output tokens, but this is not a general launch: access starts this week with a subset of cyber defenders through the Fairwind Program, under the U.S. government's voluntary pre-release testing process, with developer and consumer availability to follow.
