Google Gemini Decisions API Launches With Paid Access

Google unveiled the Gemini Decisions API on November 11, 2026. The announcement page does not include a release time or time zone. The sources reviewed do not specify who can currently use it in South Korea.

This article reviewed Google's announcement and an independent evaluation as of November 14, 2026.

Gemini Decisions API unveiled for multimodal decisions

The Gemini Decisions API evaluates predefined choices based on the input. Google identified the underlying model as Gemini Decision 1. The API is the interface through which programs call its functions, while the model makes the actual decisions.

Google said the API returns probabilities for each choice and a confidence level for its decision. Examples of use included tool selection and checking whether rules are met. These are capabilities described by the company, not figures that guarantee accuracy for individual tasks. Google announcement

Eligibility and availability dates in South Korea need confirmation

The sources reviewed are not enough to establish which accounts can use it immediately in South Korea. Support for South Korea and age requirements also need separate confirmation. The general Gemini API's support conditions should not be assumed to determine eligibility for this product.

The date on the announcement page is November 11, 2026. Without a release time or time zone, it cannot be converted to Korean time. The start date for support in Gemini in Google Cloud was not specified either.

Input costs $0.10 per 1 million tokens, with output priced at $0

Google announced an input price of $0.10 per 1 million tokens. This applies to Gemini Decision 1. Output tokens were listed at $0.

The statement that there is no output charge does not mean the entire API is free. The announced rate applies to input. Before using it, check the call limits and billing terms that apply to your account.

The independent evaluation gives it a Decision Index score of 66

Artificial Analysis gave Gemini Decision 1 a score of 66. The metric is called the Artificial Analysis Decision Index. This is an independent evaluation that should be distinguished from Google's own measurements. Artificial Analysis model evaluation

This score alone cannot establish its decision-making performance on Korean-language tasks. The sources reviewed contain no separate evaluation of Korean-language decision-making performance. To apply it to work in South Korea, check the results using the Korean-language inputs you will actually use.

Korean-language evaluations and detailed safety materials have not been confirmed

The sources reviewed contain no separate materials for assessing Korean-language performance or safety in detail. Undisclosed information should not be interpreted as proof of performance or safety. The following have not yet been confirmed.

• A separate evaluation of Korean-language decision-making performance
• Separate model and system cards
• Detailed safety evaluations
• The start date for support in Gemini in Google Cloud

Developers in South Korea should check access conditions and actual input costs

Before adopting it in South Korea, first check whether your account can access the product. Review pricing based on input tokens. Suitability for Korean-language tasks needs to be checked separately from the independent evaluation score.

Check access conditions and billing in Google's product documentation and your account interface. If you plan to use it in a Cloud environment, a separate announcement of when support begins is needed. The announced API and the Cloud availability schedule should not be treated as the same thing.
