Frequently asked questions

Gemini 4 Argon and Grok 4.20 Beta don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Grok 4.20 Beta is cheaper on both input and output: $1.25 vs $2.00 per million input tokens, and $2.50 vs $10.00 per million output tokens. Figures are base-tier rates. Grok 4.20 Beta shipped 225 days before Gemini 4 Argon, so benchmark comparisons should account for the intervening progress.

Published specifications for these two models are limited — see each model page for the latest details.
