🚀 What is Gemini 4 Hydrogen

🦜きなこ：Google officially announced Gemini 4 Hydrogen on 2026-11-12 (U.S. time). Within the Gemini 4 family, it's positioned as a model for "speeding up everyday coding and agent tasks," with the Frontier models Gemini 4 Carbon / Gemini 4 Argon handling the difficult long-term reasoning.

🐹もっちー：So, where can it be used? What's the price?

🦜きなこ：According to the official blog, the available providers are as follows. The pricing is $1.50 for input and $7.50 for output per 1 million tokens, with the same price across the entire 1 million token context.

Key Points

  • Providers: Google AI Studio (all plans), Gemini API, Gemini for business, Gemini apps, Google Search. For Google Antigravity, it's for paid AI Pro / Ultra users.
  • Pricing: $1.50 for input and $7.50 for output (both per 1 million tokens, same price across the entire 1 million token context). Input can be up to 1 million tokens, output also up to 1 million tokens.
  • Performance (official announcement): Artificial Analysis Intelligence Index is set to high at 51 (Argon is 50), xhigh at 54. 2.5 times faster than Gemini 3.8 Flash. Terminal-Bench 4.1 is 57% (Gemini 3.8 Flash is 18.2%).
  • Antigravity Orchestrator: Switches between Carbon and Hydrogen within the same session. In Terminal-Bench 4.0, 24% less quota consumption and 19% shorter completion time (similar task success rate to Carbon).
  • Google Search is also expanding globally for all users. Enhanced understanding of the intent behind multi-part questions and visual answers such as tables and images.

🐹もっちー：All the benchmark numbers are from Google's own announcements.

🦜きなこ：Yes, the numbers written here are all based on official announcements. Since they aren't third-party verification results, evaluate them yourself through your own tasks.
