01What is Gemini 4 API?

What happened

On 13–14 October Google made Gemini 4 Argon available to developers, enterprises, scientists and consumers: the API and Google Cloud went live together, the Gemini app opened it to AI Pro and Ultra subscribers, and the Antigravity coding tool began rolling it out. Partner platforms list a 1M-token context window and text, image, PDF and video input.

Why it matters

It is Google's flagship release of the quarter and lands in the same week as rival launches; Vercel, Devin and others shipped it on day one, showing that frontier models now reach developers the day they are announced.

Who it affects

Developers and enterprises on the Gemini API (Ars Technica reports 50% off API rates through November), Google AI Pro/Ultra subscribers, and teams comparing coding models.
