Do Gemini thinking tokens cost extra?
They are billed as output, at the output price. Say a request returns 500 visible tokens after 2,000 tokens of thinking: you pay for 2,500 output tokens. On Gemini 4 Argon that is $0.025 a request instead of $0.005, five times the output cost you might expect from the reply alone.
Token counts for images, video and audio follow their own rates; the Gemini token counter lists them and estimates text in your browser.
Which Gemini models are being retired?
From 1 Dec 2026, Google routes every request for Gemini 2.5 Pro to Gemini 3.8 Flash, and every request for Gemini 2.5 Flash to Gemini 3.5 Flash Lite. Your code keeps working, but the model and the price change: Gemini 3.8 Flash is $0.75 in and $3.75 out until 31 Dec 2026, then $1.50 / $7.50, against $1.25 and $10.00 for Gemini 2.5 Pro.
Shutdown dates in the table, soonest first: Gemini 2.5 Pro and Gemini 2.5 Flash on 1 Dec 2026; Gemini 3.1 Flash Lite on 7 May 2027.
Is the Gemini API free?
Yes, Google still runs a free tier, and no card is needed. The catch: free prompts can be used to improve Google products, and the free tier is not allowed for apps serving EEA, UK or Swiss users. The prices on this page are the paid tier, which you need once you pass the free limits or serve users in those regions. See is the Gemini API free for the free limits and terms, and compare it with other free LLM APIs.
