Sources & methodology

Gemini 4 Hydrogen is not on the arena.ai Agents leaderboard, so it has no rank on our default leaderboard; the other data below is for reference.

  • arena.ai Agents — agent Net Improvement, 95% interval, sessions and rank (via the public Hugging Face dataset, CC BY 4.0).
  • LMArena — Arena score (Text leaderboard with style control, the same view arena.ai shows by default), 95% confidence interval, votes and rank.
  • Artificial Analysis — Intelligence / Coding Index, output speed and latency (medians).
  • OpenRouter — Route prices, context length and listing date.

Arena scores use the Bradley-Terry model (not Elo); ± is the half-width of the 95% confidence interval. Latency figures are Artificial Analysis medians; for reasoning models, time to first token and to first answer include the thinking phase. Data syncs daily at 14:20 (UTC+8).

Limits: Arena scores come from anonymous users voting on chats, so they reflect conversational preference rather than agent or coding benchmarks; with few votes the interval is wide and ranks move. Prices and speeds change as providers update them.

FAQ

What rank is Gemini 4 Hydrogen right now?

Gemini 4 Hydrogen is #13 on our leaderboard of 72 scored models (Arena score 1490.4); its raw LMArena rank is #15.

How fast is Gemini 4 Hydrogen?

Artificial Analysis measures about 249 output tokens per second, 59 s to the first token and 59 s to the first answer token; it is a reasoning model, so latency includes thinking time.

How close is Gemini 4 Hydrogen to the models ranked next to it?

It is 0.5 points behind Muse Spark 1.1 (1490.9) and 0.7 points ahead of Claude Opus 5 (1489.7); gaps smaller than the confidence interval (±9.0) are not significant.

Why is Gemini 4 Hydrogen marked Preliminary?

It has only 4,741 votes on LMArena and a 95% confidence interval of ±9.0; with few votes the score can move noticeably as new votes arrive, so treat the rank as provisional. We mark models with fewer than 5,000 votes or ± above 10 as Preliminary.

Is Gemini 4 Hydrogen open source? Can it be self-hosted?

Gemini 4 Hydrogen is a closed model, available only via official APIs or hosted services.

What is the context length of Gemini 4 Hydrogen?

1.05M (1,048,576 tokens, as listed on OpenRouter).

Gemini 4 Hydrogen vs Muse Spark 1.1: which is better?

On the LMArena Text leaderboard Gemini 4 Hydrogen scores 1490.4 and Muse Spark 1.1 scores 1490.9 (a 0.5-point gap, within the confidence interval, so not significant). On price, Gemini 4 Hydrogen costs $7.50 and Muse Spark 1.1 $4.25 per 1M output tokens.

Is there a cheaper model close to Gemini 4 Hydrogen?

Yes: Gemini 3.8 Flash scores 1496.7 on the Text leaderboard (Gemini 4 Hydrogen: 1490.4) and costs $3.75 per 1M output tokens, about 50% less than Gemini 4 Hydrogen ($7.50).

Where does the Gemini 4 Hydrogen data come from and how often is it updated?
