Google’s new frontier AI model Gemini 4 Argon goes to cybersecurity defenders first

Google LLC today began rolling out Gemini 4 Argon, a frontier artificial intelligence model that beats rival models from Anthropic PBC and OpenAI Group PBC on most of Google’s benchmarks, to vetted cybersecurity defenders. Outside Google’s own teams, only members of its Fairwind Program can use Argon for now. The program opened Sept. 3 with the smaller Gemini 3.8 Flash Cyber model and has since signed up more than 650 organizations, including CrowdStrike Holdings Inc. and Palo Alto Networks Inc. Koray Kavukcuoglu, chief AI architect at Google, wrote in the announcement that releasing capabilities at this level “requires a phased approach.” Google is taking part in the U.S. government’s voluntary process for pre-release model access and says it is still hardening safeguards against misuse for cyberattacks or weapons development.
