Frequently asked questions

Gemini 4 Argon and GPT-5.3-Codex-Spark don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only Gemini 4 Argon has a verified first-party API price: $2.00 per million input tokens and $10.00 per million output tokens. No pay-as-you-go API rate is tracked for GPT-5.3-Codex-Spark. GPT-5.3-Codex-Spark shipped 230 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.
