Gemini 4 Argon goes first to vetted defenders through Google's Fairwind Program, and Google says those defenders and its own teams get it without cyber guardrails. The headline claim is autonomous discovery, validation and patching of critical vulnerabilities. The benchmark it cites is a tie at 68 percent, and the vulnerability it showcases is unnamed.
Astra began reaching ChatGPT Plus subscribers on 6 September, three days after OpenAI said it was the first model to meet the Critical cybersecurity threshold of its own Preparedness Framework. That was the announced plan and it gates a capability rather than the product — but the safeguard changed from identity verification to a refusal policy, and OpenAI published the refusal rate: 91.5%.
Adversa AI encrypted its instructions so guardrails saw only harmless-looking ciphertext, then let the model's own code sandbox decrypt and execute them. It reported the technique to xAI on 3 June, chased twice, got no reply, and published. Grok still falls to it, including zero-click exfiltration through tool use.
