Build more responsive apps with the Decisions API
OpenAI launches Decisions API for fast, low-cost application decision-making
“Fast, focused, low-cost decisions for any application.”— OpenAI
OpenAI announced the Decisions API, a new offering positioned as a lightweight, cost-efficient layer for embedding fast decision logic into applications. The framing around 'low-cost' and 'focused' suggests a smaller, specialized model or routing layer distinct from full chat completions. For developers building agentic or real-time systems, this signals OpenAI expanding its tiered API portfolio beyond general-purpose models.
