What was announced?

OpenAI unveiled a new developer interface called the Decisions API on October 22, 2026. According to the company's brief post, the API delivers "fast, focused, low-cost decisions" for applications.

What it does

As the name suggests, the API appears to focus on a specific decision point rather than generating long, complex responses. The approach aims to let apps make lighter, faster calls instead of running a heavy model on every request.

Why it matters

Cost and latency are two of the biggest constraints in production. OpenAI's emphasis on low cost suggests the API targets high-volume, repetitive decision flows.

What's still unknown

OpenAI's short post does not include a model name, pricing, availability regions or technical limits. Those details are expected in the developer documentation.
