tl;dr: Google announced Gemini 4 Argon, a frontier model with a 1M output token limit, priced at $2/M input and $10/M output tokens, initially rolling out to trusted cyber defenders before wider release. It claims state-of-the-art results on benchmarks like DeepSWE v1.1 (77.9%), LVBench (91.7%), and CWE-bench v1 (68%), and is already being used internally at Google for tasks like C++ to Rust migrations and data center memory optimization. Google is also releasing it without cyber guardrails to trusted defenders and emphasizing new safeguards against misuse, prompt injection, and misalignment.
