OpenAI has introduced the Decisions API in public beta—a powerful new tool for developers. It allows applications to make complex decisions about selecting the appropriate model, tool, or action almost in real time.

The API runs on GPT-6 Luna and significantly surpasses previous methods, being up to 10 times faster than the Responses API. It accepts both text and graphical input data.

Developers can use it for intelligent request routing to the most suitable resource, as well as for complex data analysis, including image evaluation and determining the probability of statement truthfulness. The API supports three types of outputs: predicates (probability assessment), choices (selection from predefined options), and evaluations.

Why it matters

  • —Increases the speed of AI systems: the API works 10 times faster than previous methods.
  • —Allows for the creation of more complex and intelligent applications capable of independently selecting the necessary tool or model.
  • —Expands data analysis capabilities, including image processing and fact probability determination.

Key facts

  • The API is available in a public beta version.
  • Operates on the GPT-6 Luna base.
  • Supports input data in text and graphical formats.
  • Outperforms the Responses API by up to 10 times in speed.
  • Provides three types of outputs: predicates, choices, and evaluations.
