Frequently asked questions

Gemini 4 Argon and GPT-5.4 mini don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. GPT-5.4 mini is cheaper on both input and output: $0.75 vs $2.00 per million input tokens, and $4.50 vs $10.00 per million output tokens. GPT-5.4 mini shipped 197 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.
