OpenAI launches Decisions API for fast choices, targeting Jev
At DevDay, OpenAI announced a Decisions API that narrows open-ended generation to picking from predefined options and returns a choice plus confidence that code can consume directly, which The Decoder says runs about ten times faster than the Responses API. It currently supports only GPT-6 Luna, at $0.10 per million input tokens with free output tokens in public beta, according to The Decoder, while InfoQ describes it as a limited preview with pricing and customization details to come at general availability. OpenAI also cut its paid API tiers from five to three: Build, Launch and Grow.
Routing classification and routing decisions to the smallest, cheapest model could become a high-frequency building block for agent workflows, putting the decision-model startup Jev under direct pressure.
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.
