## Summary

OpenAI released the Decisions API on October 22, 2026, designed for quick, structured AI decisions rather than long-form text. It returns predefined answers—probabilities, choices, or scores—in fixed formats like JSON, enabling apps to route inquiries, classify content, or trigger actions without waiting for full responses.

The API is about 10 times faster than using GPT-6 Luna with the Responses API, according to OpenAI’s benchmarks. It supports up to 400 simultaneous queries and integrates with GPT-Live for real-time voice interactions, such as adjusting avatars or escalating issues. However, OpenAI emphasizes that confidence scores are not ‘automatic execution permits’ and warns developers to test thresholds with real-world data to avoid errors. The API is positioned as a complement—not replacement—for text generation or tool execution, with a focus on predefined workflows.

## Key points

- OpenAI’s Decisions API returns structured answers (probabilities, choices, scores) in fixed formats like JSON for quick app decisions
- Officially 10x faster than GPT-6 Luna’s Responses API, with support for up to 400 simultaneous queries per request
- Integrates with GPT-Live for real-time voice interactions, but requires manual threshold-setting for confidence-based routing

## Why it matters

The API enables faster, automated decision-making in apps without sacrificing control, reducing latency in workflows like customer support or content routing.
