16 models across 2 tiers

Gemini API pricing in 2026

Google has models in the mid and fast tiers: mid-tier (Gemini 3.1 Pro) and fast (Gemini 3.5 Flash, 3 Flash, 3.5 Flash-Lite). All four Gemini models list under $2.00/MTok input. GPT 5.6 Luna took the outright budget floor in August 2026. Google has a 90% cache read discount with no cache write surcharge, which makes it the cheapest family to maintain a prefix that changes often.
