Gemini 4 Argon arrives in Antigravity and Antigravity CLI

What changed

From October 13, Gemini 4 Argon is available in the Antigravity desktop app and Antigravity CLI for Google AI Pro and Ultra subscribers, inside Antigravity for eligible Gemini Enterprise subscriptions, and to businesses through the Gemini API. Google cited internal figures only, such as a 35% rise in agent-written code over four weeks, and gave no public benchmarks, rate limits or minimum CLI version.

Who it affects

Antigravity users on Google AI Pro/Ultra or eligible Gemini Enterprise plans.

What to do

Update Antigravity and the CLI to see Argon in the model list, and keep an eye on quota since limits weren’t published.
