Interesting, Google's own article says it's rolling out today to Ultra subscribers. No mention of Pro.

Weirdly, the post OP linked says:

> Gemini 4 Argon is available today for Google AI Pro and Ultra subscribers

		It's indeed very confusing, it's either 1. It's available to Pro in Gemini app, but NOT antigravity (for coding) 2. It's a phased rollout and Ultra got it first, Pro is coming later The latter blog post is specifically "Argon in Antigravity" versus the other blog post is about Argon in general, so seems like #1 is more likely.
