Google Gemini 4 Hydrogen runs 2.5 times faster than 3.8 Flash and slightly outperforms Argon.

Crypto Briefing compares two versions within the same product line and also mentions efficiency alongside speed.

· The 2.5× figure is relative to 3.8 Flash; the source provides no absolute figures, testing conditions, or specific task types.
· “Slightly outperforms Argon” does not quantify the gap and should be treated only as a ranking.
