Google discounts Gemini 4 Argon cached input tokens by 95%

Top News · 1,184 HN points

Google is opening Gemini 4 Argon in stages for long-horizon coding, enterprise work, multimodal tasks, and cybersecurity defense. Its announced introductory API rates are $2 per million input tokens and $10 per million output tokens.

Here’s what changed:

• Cached input tokens cost 95% less, which can lower bills when a request reuses prior context.
• Argon’s output-token limit is 1 million, up from 64,000, leaving more room for long responses.
• Google reports 77.9% on DeepSWE v1.1 and 68% on CWE-bench v1, tied for first.
• Google says the model can find, validate, and patch critical software vulnerabilities.

One catch: Access is currently limited to trusted cyber defenders through the Fairwind Program and a cohort of trusted testers. Google plans broader access starting with paid API customers and Google AI Ultra subscribers.
