Google launches flagship AI model Gemini 4 Argon for developers, businesses

Alphabet's Google unveiled its top AI model, Gemini 4 Argon, to developers and businesses on Wednesday, aiming to recapture market share from OpenAI and Anthropic following delays and leadership changes at its DeepMind lab. Designed for intricate, multi-step tasks in coding, finance, law, cybersecurity, and science, the model's API pricing begins at $2 per million input tokens and $10 per million output tokens, with a price hike set for November 30.

The launch comes after a challenging period for Google's AI initiatives. In September, it was announced that Gemini 3.5 Pro, initially slated for June release, would not be released, and DeepMind saw a leadership overhaul after co-founder Demis Hassabis stepped down and key Gemini model leaders departed. Argon is now accessible to paying customers via Google's AI tools, including Google AI Pro and Ultra subscribers who can access it through the Gemini app, AI Mode in Search, and the Antigravity coding tool, which is reserved for Ultra subscribers.

Teams employing Argon in Antigravity experienced a surge in agentic code submissions by over 35% and a reduction in code rollbacks by nearly one-third, according to Google. Early adopters of the model include Deloitte, LexisNexis, Ambience Healthcare, and Isomorphic Labs. Google also announced the expansion of its Fairwind Program to include hundreds more cybersecurity partners.

This program provides these partners with a version of Argon without its cyber safeguards, a move that was previously limited to select cybersecurity allies.

Additionally, Google will offer 10,000 scientists six months of complimentary access to Antigravity's highest usage tier.
