Google DeepMind announced Gemini 4 Argon — a frontier model for long-horizon professional work that raises the output token limit from 64,000 to 1 million, rolled out first and in phases only to trusted cyber defenders in the Fairwind Program
Why it matters
Company-reported scores: DeepSWE v1.1 77.9%, AutomationBench 51.3% (first), LVBench 91.7%, CWE-bench v1 68% (tied first). The introductory price is $2/$10 per 1 million tokens (later $4/$20), and Google said it is taking part in the US government's voluntary pre-release access process as it widens access. Internally, Google said Argon agents freed more than 300 TiB through data center memory optimizations
