Google AI Studio 的價格、免費額度與實際用法
Free development platform to play with the latest Gemini model, with the largest free quota in the industry
Development purposes are almost free with rate limits, and the exact RPM/TPM/RPD depends on the account level as stated on aistudio.google.com/rate-limit. For the Gemini 2.5 series, Search grounding is free for 1,500 times/day, and then US$35/1,000 times, while Maps grounding is also free for 1,500 times/day, but then US$25/1,000 times (confirmed on the official website on 2026-07-27 that the excess fee rates for the two are different). Other Search/Maps models are free for 500 times/day. For the Gemini 3 series models, the first 5,000 prompts per month are free (both Search and Maps), and then US$14/1,000 times for queries.
The free quota is indeed generous, but be aware that the content in the free tier may be used by Google to train models, so be cautious when uploading sensitive or customer data.

The key difference between the free tier and the paid tier is not just the quota, but whether the data will be used for training - it is recommended to pay for commercial or sensitive data processing.
