Google is now rolling out support for Gemini 4 Argon to Antigravity, its AI coding tool.
Gemini 4 Argon is Google’s latest flagship AI model, announced at the end of September and having widely rolled out to users earlier this week . Now, it’s also available within Antigravity.
Antigravity is an agentic development platform, as Google describes it, which leverages AI and agents to assist in coding and building apps. Google announced that Argon would be available in Antigravity earlier this week, and it’s now actively rolling out to AI Pro and AI Ultra subscribers – we’re seeing it live on our end, too.
In a post on Twitter/X, Google adds that there’s “a separate weekly-only Argon quota” on top of the existing quota for Gemini 3.8 Flash, meaning you’ll be able to use the model that best suits your needs. Google says that Argon is “designed to tackle your hardest problems.”
Google also provided a host of examples of how Argon in Antigravity has been used internally, including:
YouTube comment optimization: Argon in Antigravity helped the team cut the CPU footprint of YouTube’s comments frontend in half. By tracing production profile data, Argon identified that redundant emoji rendering alone accounted for nearly 45% of server overhead, leading to 12 targeted optimizations. The updates reduced server comment-load latency by 30 ms and dropped client end-to-end latency by 20 ms.
