Top performance in benchmarks

Google reports impressive results in benchmarks: 77.9% on DeepSWE v1.1 (software engineering tasks test), 51.3% on Zapier's AutomationBench (where it ranks first), and 91.7% on LVBench (long video test). On CWE-bench v1, which evaluates the ability to fix security vulnerabilities, Argon scores 68%, ranking first.

Superior results in vulnerability discovery tests

In internal tests, Argon demonstrated superior capabilities in discovering vulnerabilities in complex codebases in 20 programming languages. In Wiz's black-box penetration tests, where the model analyzes live web systems without access to the source code, Argon outperformed Flash Cyber in attack surface mapping, vulnerability discovery, and producing proof of concepts.

Launch planning and introductory prices

Gemini 4 Argon will initially be available at 2 dollars per million input tokens and 10 dollars per million output tokens. Stored input tokens will cost 95% less than the standard price. After the introductory period, prices will double to 4 and 20 dollars respectively.

Gradual approach for a safe release

Google stated that a gradual approach is necessary to safely release capabilities at this level. It is still adjusting the guardrails based on initial user feedback and participates in the U.S. government's voluntary pre-release model access process.

Improvements in safeguards

Before general release, Google is strengthening safeguards against misuse in cyber and CBRN (chemical, biological, radiological, and nuclear) contexts. Both internal and external teams have tested the systems, with monitors constantly observing Argon's reasoning and actions, intervening when necessary.
