Gemini Pricing: Google AI Pro, Ultra and API Costs Explained
Gemini costs $0 on Free, $19.99/month on Google AI Pro and $249/month on Google AI Ultra; the API bills per token at $2 input / $12 output per 1M for Gemini 3.1 Pro, $0.75 / $3.75 for Gemini 3.8 Flash and $0.30 / $2.50 for Gemini 3.5 Flash Lite. Google retired the old 'Gemini Advanced / Google One AI Premium' framing, so older pricing pages built on that tier or on pre-Gemini-3 API rates are misleading for buyers comparing today's plans.
Bottom line
Use Free unless you actually need higher limits or Google-app integration. Google AI Pro at $19.99 is the mainstream paid plan and is strongest for people already living in Gmail, Docs, Drive and NotebookLM. Ultra at $249 is a specialist high-access plan and should be justified by concrete usage, not curiosity. Developers should price against Gemini 3.1 Pro, 3.8 Flash and 3.5 Flash Lite rather than older rate cards; Flash and Flash Lite are the cheap tiers for high-volume agent steps.
