Google Rolls Out Gemini 4 Hydrogen: 2.5x Faster Than Flash 3.8, 5x Fewer Fabrications
Ars Technica AI · rss · 2026-11-13
Google continues its elemental naming scheme with Gemini 4 Hydrogen, positioned to replace the faster, more economical Flash models. It has already replaced Gemini 3.8 Flash across Google's products.
Unlike the staged rollouts of Argon and Carbon—which began with cybersecurity researchers and were restricted to top-tier subscribers—Hydrogen is broadly available immediately.
Key claims from Google:
- Runs in four thinking levels (low, medium, high, and the new xhigh); even in high mode it's 2.5x faster than Flash 3.8
- Reduces "fabricated claims" by more than 5x per Google's analysis
- Code generation jumps significantly, more than tripling 3.8 Flash's Terminal-Bench score
- Scores 54 on the Artificial Analysis Intelligence Index in xhigh mode, beating Argon's 50
