OpenAI Decisions API Hits Public Beta With 10x Faster Typed Answers
OpenAI’s Decisions API is now in public beta on GPT-6 Luna. It returns typed probabilities, choices and scores about 10x faster than the Responses API, billing $0.10 per 1M input tokens with no output charges.
OpenAI has launched the Decisions API in public beta, offering faster structured outputs for text and image analysis compared to its previous Responses API.
What happened
OpenAI released the Decisions API as a public beta, enabling developers to process text and images into structured data types. The API claims 10x speed improvements over the Responses API and offers pricing at $0.10 per 1M input tokens. It competes with TypeSafe Jev, which has lower input costs but limited features.
Why it matters
The API addresses a common need for structured decision-making in AI applications, particularly for developers requiring probabilistic outputs, classifications, or scoring systems. Its speed and pricing model may influence adoption in enterprise workflows.
- Decisions API excels in scenarios needing probabilistic or categorical outputs
- Cost structure favors applications with high input token volumes
- Competitor TypeSafe Jev offers lower pricing but fewer features
- Beta status requires caution for mission-critical systems
- Image input support differentiates it from some competitors
The bigger picture
The API could streamline AI integration for applications requiring fast, structured outputs. However, its beta status and lack of independent validation may limit immediate enterprise adoption compared to competitors.
OpenAI's Decisions API introduces a specialized tool for structured AI outputs, offering speed and pricing advantages while competing with alternative solutions in the decision-making API space.
Technical details
- Three question types: predicate (binary probability), choice (option selection with probabilities), score (weighted level ratings)
- Uses gpt-6-luna model with 1,050,000-token context window
- API endpoint: POST /v1/decisions with base64 image input support
- Supports SDKs for Python, JavaScript, Go, Ruby, and Java
- Compliance features: Zero Data Retention, HIPAA, and EU/US data residency
FAQ
What types of outputs does the Decisions API support?
It returns probabilities (predicate), option choices with confidence scores (choice), and weighted level ratings (score).
How does the Decisions API differ from OpenAI's Responses API?
It provides structured, typed outputs instead of prose and claims 10x faster processing times.
What are the main competitors to the Decisions API?
TypeSafe Jev offers similar functionality with lower input pricing but lacks image input support and OpenAI's compliance features.
Is the Decisions API suitable for production use?
It is currently in beta with no independent evaluation data, so caution is advised for critical applications.
What are the cost implications for using the API?
Pricing is $0.10 per 1M input tokens with no output charges, but regional premiums and long-context multipliers may apply.
