OpenAI Launches Decisions API: 10x Faster Routing for Production Decision-Making

Why it matters

💻 Developer · Purpose-built for high-throughput decision pipelines. Use it for classification, routing, and scoring in production systems. The flat input-only pricing and 10x speedup make it viable for millions of decisions without inference cost exploding. No need to pay for output tokens.

📦 Product · Enables real-time personalization, routing, and content moderation at scale without latency or cost penalties. You can add intelligent decision-making to user-facing features without slowing down response times or crushing margins on high-volume features.

🎨 Design · Faster decisions mean tighter response loops and snappier UX. Decisions in milliseconds instead of seconds keep user interactions flowing naturally, which matters for real-time applications.

📈 Business · Demonstrates OpenAI's shift toward disaggregated inference—different systems for different tasks rather than forcing one large model everywhere. The $0.10 per million input tokens pricing is commoditized; the value is the speed and specialization.

🤔 Just Curious · Shows LLM providers unbundling generalist models into task-specific optimizers. A decision classifier doesn't need language generation capability, so why pay for it? This reflects maturing ML infrastructure where specialist models outcompete generalists on cost and latency.
