Google Launches Flagship AI Model Gemini 4 Argon for Developers, Businesses
The model is available to Pro and Ultra subscribers and developers, with introductory pricing set at $2 per million input tokens, Google said.
On Tuesday, Google released Gemini 4 Argon, its new flagship AI model, to Pro and Ultra subscribers in the Gemini app and through the Gemini API.
Seeking to reassert itself in the frontier AI race after skipping Gemini 3.5 Pro, Google developed Argon through internal testing with more than 100,000 employees using Antigravity.
Artificial Analysis data shows Argon matches OpenAI's GPT-6 Astra on the Intelligence Index at 60 percent of the cost, while internal tests showed 35 percent higher AI-generated code production.
Developers can access Argon via the Gemini API at $2 per million input tokens and $10 per million output tokens through November 30, 2026.
After November 30, rates rise to $4 and $20 per million tokens, while Google deploys safety monitors tracking reasoning to block unintended model workarounds.
Argon surpasses any model released so far for the amount of tokens it can handle: up to a million both in and out. It is designed to meet the needs of the deep work, a type of in-depth work for articulated problems and professional contexts of high complexity
With Gemini 4 Argon, Google wants to record competing products such as Claude Opus 5.5 and GPT-6 Astra. Now access to the new AI model is unlocked, but some paying customers are running out.
