OpenAI Launches Decisions API Public Beta, Up to 10x Faster Decision-Making
OpenAI announced on October 7 that the Decisions API has entered public beta and is now open to all developers. Powered by GPT-6 Luna, the API is built for one specific task: enabling applications to make decisions quickly in near-real-time settings, with officials claiming decisions can be made up to 10x faster than calling GPT-6 Luna via the Responses API.
Confirmed
- The Decisions API is in public beta for all developers, announced by OpenAI's official and developer accounts (@OpenAIDevs)
- Powered by GPT-6 Luna, it handles classification of text and images, request routing, and input scoring
- How it works: developers give the model an input, define a question with a set of candidate answers, and the model's choice determines what the program does next
- Performance: officials say decisions are up to 10x faster than calling GPT-6 Luna via the Responses API, making it suitable for near-real-time selection of the right model, tool, or action
Why it matters
- It pushes large models further from "generating content" toward an infrastructure role of "routing and decision-making for applications," ideal for high-frequency, lightweight tasks like classification, routing, and scoring
- The 10x speedup means decision points previously deemed too latency-sensitive for large models (such as request routing) now have an engineering-viable alternative, potentially reshaping how model calls are architected in applications
