Access and use
API model id: gemini-3.8-flash. Google offers it through the Gemini API, Google AI Studio and Gemini Enterprise Agent Platform. The input limit is 1,048,576 tokens and the output limit is 65,536 tokens. Paid tier pricing is an introductory US$0.75 per million input tokens and US$3.75 per million output tokens through 31 December 2026, then US$1.50 and US$7.50 from 1 January 2027 (pricing page read 7 November 2026); output includes thinking tokens. On the free tier, Google uses prompts and responses to improve its products and machine learning technologies, human reviewers may read them, and Google asks users not to submit sensitive, confidential or personal information. Google says paid-tier prompts and responses are not used to improve its products, but it logs them for a limited period to detect Prohibited Use Policy violations and for legal disclosures, and that data may be stored or cached in any country where Google has facilities. Separately, your project's own Logs and Datasets logging is on by default for Interactions API calls and for Generate Content calls in projects created on or after 26 October 2026, with logs kept for up to 55 days by default; a dataset you choose to share with Google may be used to train its models. Proprietary; API terms apply.
Who it is for
Developers running high-volume or cost-sensitive agents on the Gemini API who still need a 1 million token context and tool use.
