OpenAI 推出 Decisions API，Jev 承压
在 DevDay 上，OpenAI 发布 Decisions API，把开放式生成收窄为从预设选项中作答，并返回可直接供程序使用的选择与置信度，据称速度约为 Responses API 的十倍。该 API 目前仅支持 GPT-6 Luna，据 The Decoder 报道输入价格为每百万 token 0.10 美元、输出 token 免费并已进入公开测试；InfoQ 则称它仍是限量预览，定价与可调优等细节要等“全面推出时”才公布。OpenAI 同时把付费 API 层级从五档压缩为 Build、Launch、Grow 三档。
用最小、最便宜的模型承担分类与路由决策，可能成为智能体工作流里的高频基础组件，也让主打“决策模型”的 Jev 面临正面竞争。
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.
