Google has just launched Gemini4Hydrogen (Hydrogen), a new model focused on speed and execution efficiency—and as soon as it debuted, it embarrassed its own Argon: on a third-party intelligence index leaderboard, Hydrogen scored 51 points, with its Xhigh tier reaching 54, beating the higher-positioned Argon's 50; the default tier is 2.5 times as fast as the previous-generation Flash, hallucinations are cut by more than 80%, and its API price is lower than Argon's.

Orchestrator switches models for you automatically

Google didn't let its two flagship models go it alone. The newly launched Antigravity Orchestrator can automatically switch between Carbon and Hydrogen within the same task as work progresses: Carbon first breaks down the task and sets a plan, then hands it to Hydrogen to modify code and run tests; if it hits a snag, it hands it back to Carbon—no manual switching needed throughout. Internal tests show it comes close to the success rate of using Carbon alone, while saving 24% of quota and running 19% faster. It is currently available first to AI Ultra users.

The speed frenzy also comes with a reality check: some point out that if an answer is wrong, rerunning it may cost more than one slow but accurate response. Developer @SPAC89 built a Three.js project with Hydrogen in two hours, using only 5% of a Pro subscription's weekly quota, and called it almost unlimited; while @mattyapro's complaint is the most down-to-earth: the model you actually use every day matters more than the model that tops the leaderboard.
