Google Releases Gemini 4 Argon Globally Under Launch Discount

Google has released its Gemini 4 Argon artificial intelligence model globally across Search, the Gemini consumer app, and its developer API, according to reporting by The Next Web .

The company set temporary promotional pricing for developers at $2 per million input tokens and $10 per million output tokens, halving its standard scheduled rates of $4 and $20 per million tokens. Google said the discount will run for at least one month without a fixed expiration date. Individual consumers can access the model via a Gemini Pro subscription starting at $19.99 per month.

Tulsee Doshi, product lead for Gemini at Google DeepMind, told Business Insider that Argon is a "powerhouse" and the initial release in a wider model family. Google claimed Argon ranks first on the Vals Index, a benchmark evaluating tax, legal, coding, and financial performance.

Before its general commercial release, Google supplied Argon without default safety guardrails to an initial group of cybersecurity defenders through a program called Fairwind. That access is now expanding to hundreds of partner organizations. Cloud security firm Wiz used the unredacted model to audit critical infrastructure and reported finding a security bypass that exposed a master key in healthcare software.

The testing expansion comes amid regulatory scrutiny in the European Union, where the 36-person European AI Office classifies cyber offense as one of four systemic risks alongside biological threats, loss of control, and mass manipulation. The regulator, which can fine non-compliant organizations up to 3% of global annual turnover, has faced hurdles securing access to certain frontier models.

Google published defensive safety statistics for the model, noting that external biological red-teaming unlocked fewer than 1% of tested sub-tasks, while coding shortcut attempts fell to 2%. An integrated runtime monitor that reviews reasoning steps during execution limited prompt injection attack success rates to 0.7%.

Internally, Google reported engineering gains through Antigravity, its agentic development tool powered by Argon. Agentic code submissions grew by more than 35%, rollbacks declined by nearly a third, and engineers completed a Chrome refactoring project in weeks rather than months. Google also claimed Argon helped identify counterexamples to a 1967 physics conjecture on fusion reactor magnetic fields and trained a humanoid robot to play cornhole from video footage. Access to Antigravity requires an Ultra tier subscription starting at $99.99 per month, while free-tier users were shifted to Google's smallest model four days ago.
