Google released Gemini 4 Argon to cyber defenders first; OpenAI disrupted a distillation campaign
Wednesday. Written from the atlas logs (checked against sources 6 Oct 2026); numbers are company-reported unless noted.
Google released Gemini 4 Argon first to vetted cyber defenders, the third lab to stage a top model's release around cyber risk, and OpenAI said it disrupted a campaign to copy its models' reasoning.
Gemini 4 Argon has a one-million-token output limit and a reported 77.9% on DeepSWE v1.1. Its first users are vetted cyber defenders, under the US voluntary pre-release access process. Developers, enterprises and paying consumers come later. Anthropic staged Mythos this way in April, and OpenAI did the same with GPT-6 Astra in September.
OpenAI said it disrupted a campaign to extract protected reasoning from its models. The campaign involved about 16,000 requests from more than 4,000 users in a two-day spike in July, and OpenAI attributed a core cluster to people associated with Moonshot AI. Read with yesterday's GLM-5.3 study, the day shows labs gating their strongest models while others close the gap fast.
