OpenAI opens Decision API to all users

The pricing detail is the real story here: at $0.10 per million input tokens, OpenAI is positioning this API as a low-cost, high-volume primitive rather than a premium product, which matters for developers building automated decision layers into applications. The absence of detail on model scope and availability limits any read on how broadly this competes with existing inference offerings. For teams already wiring decision logic into products, the open question is whether this pricing holds as usage scales and whether the missing scope details emerge.
