According to a report by MarkTechPost, OpenAI has launched the public beta of its new Decisions API running on GPT-6 Luna. The interface is designed to deliver structured outputs, providing typed probabilities, choices, and scores. Pricing for the new tier is set at $0.10 per one million input tokens, with no additional charges applied for output tokens.
Speed and Performance Claims
The core technical development highlighted in the announcement is the processing speed of the Decisions API. The system reportedly returns typed answers approximately ten times faster than the standard Responses API. This efficiency in generating structured probabilities and choices represents a notable architectural shift for developers handling high-volume classification and decision-making tasks.
Unknowns and Future Implementation Details
Despite the release of the public beta, several technical specifications remain undisclosed. The announcement did not specify the underlying hardware architecture enabling the tenfold speed increase, nor did it outline specific latency benchmarks for different payload sizes. Additionally, the documentation currently lacks details regarding rate limits, regional availability schedules, or any timeline for a general commercial release beyond the initial beta phase. Developers will need to monitor OpenAI announcements for further integration guides.
The Decisions API is available now for developers utilizing the GPT-6 Luna model within the newly opened public beta framework.
