DeepMind released Gemini 4 Argon, a next‑generation model Google says delivers frontier performance on complex tasks including software engineering, enterprise knowledge work (legal and finance) and cybersecurity defense. Initial access is limited via the Fairwind program to trusted cybersecurity defenders and will expand to developers, enterprises and consumers after additional safety measures. Pricing is $2 per mln input tokens and $10 per mln output tokens; cached input tokens are priced 95% below standard input tokens (implying about $0.10 per mln). Argon supports up to 1 million‑token outputs, versus the prior ~64k token limit. Google reports internal uses for code development, research and engineering optimization, including helping quantum computing teams tune algorithms and analyzing data‑center operations to free more than 300 TiB of memory. Google cites benchmark results of 77.9% on DeepSWE v1.1 software engineering tests and 68% on CWE‑bench v1 vulnerability repair (tied for top models). Before wide release Google says it will strengthen anti‑abuse systems, prompt‑injection defenses, model behavior monitoring and sandboxing; Argon will be made available to paid API customers and Google AI Ultra users.(金十)
