Frequently asked questions

Gemini 2.0 Flash-Lite and GPT-4 don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only GPT-4 has a verified first-party API price: $30.00 per million input tokens and $60.00 per million output tokens. No pay-as-you-go API rate is tracked for Gemini 2.0 Flash-Lite. GPT-4 shipped 694 days before Gemini 2.0 Flash-Lite, so benchmark comparisons should account for the intervening progress.

Context windows are 1M (Gemini 2.0 Flash-Lite) vs 8k (GPT-4).
