导读
OpenAI 公布 API 平台更新，重点是 Decisions API：面向"把复杂评估收敛成简单决策"的任务——是/否概率、预定义类别单选、量表评分，可处理文本与图像，速度约为 Responses API 的10倍。现公开 beta、GA 在即；暂只支持 gpt-6-luna，定价每百万输入 token $0.10、输出免费。官方举例包括照片损伤检测、客服路由与文档分类。
推荐理由
API 层产品发布：速度口径(约10x)、价格(入$0.10/出免费)、支持范围(gpt-6-luna)、三类响应形态与用例齐全，属"新推理形态按任务切分"的产品信号。与包内定价战(Sol 发布)同线；作为短讯信息量不足以越过 T2=76 精选线。

OpenAI announced two updates to its API platform. The new Decisions API evaluates text, images, or both, running about ten times faster than the Responses API. It's in public beta now, with general availability coming soon. Only gpt-6-luna is supported so far, at $0.10 per million input tokens. Output tokens are free.
The API handles three response types: yes/no probabilities, picks from predefined categories, and scale-based ratings. Use cases include damage detection in photos, automatic customer inquiry routing, and document classification, OpenIA says. It supports zero-data retention and HIPAA-compliant use in the US and Europe. The Decisions API is likely OpenAI's response to the mini-trend of "decision models" that Jev kicked off in mid-September .
OpenAI also cut its paid API tiers from five down to three: Build, Launch, and Grow. Organizations move up automatically when their total credit purchases hit the next threshold. Monthly usage limits sit at $500, $5,000, and $200,000.
