The fastest return in small-business automation comes from repetitive classification decisions - sorting leads, routing tickets, tagging invoices - where staff spend minutes on choices a model handles in milliseconds. OpenAI's new Decisions API targets exactly that layer, lowering the entry bar for ROI math at small volumes.
OpenAI just shipped the Decisions API, aimed at fast, focused, low-cost inference for classification and routing calls inside applications. Instead of pricing every decision like a full chat completion, it covers the narrow moments when you only need a label, a category, or a yes/no answer.
What this changes for a small business
If you are stuck on where to begin, pick a decision your team repeats hundreds of times a week: which lead goes to which sales rep, which inbound email is a complaint, whether a scanned document is a contract or an invoice. A Decisions-style endpoint moves per-call cost into fractions of a cent, so the payback period for a routing step shrinks from months to weeks even at modest volumes. Inside something like a tender risk analysis pipeline, this layer handles most of the classification load and the heavy reasoning model only wakes up for edge cases.
Why it matters: Cheaper decision calls shift the ROI threshold downward, so owners can automate smaller, boring processes that used to be too marginal to justify a project.
