Gemini 4 Argon Launches: Pricing vs GPT-6 and Claude Opus 5.5

What's new in Gemini 4 Argon?

FAQ

What is Gemini 4 Argon?

A new Google model released via the Gemini API and a $100/month subscription, noted for high-quality SVG generation in developer tests.

How does Gemini 4 Argon pricing compare to rivals?

At launch, $2 input and $10 output per million tokens — half of Claude Opus 5.5 and one-fifth of GPT-6 Astra — but it doubles on December 1 to match Opus 5.5.

Should MENA teams adopt Gemini 4 Argon now?

Current pricing makes testing worthwhile, especially given relatively low agentic benchmark costs, but budgets should account for the December price doubling.

Why does benchmark cost matter more than token price?

Because what matters is how many tokens a model consumes to complete a goal inside an agentic harness, not the raw per-token price.
