OpenAI launches Decisions API offering ~10x faster evaluations, trims API tiers to three
OpenAI announced the Decisions API on its API platform, which evaluates text, images or both and is said to run about ten times faster than the Responses API. It is in public beta and currently supports only gpt-6-luna, priced at $0.10 per million input tokens with output tokens free, returning yes/no probabilities, picks from predefined categories, or scale-based ratings. OpenAI also cut its paid API tiers from five to three—Build, Launch and Grow—with monthly usage limits of $500, $5,000 and $200,000.
Why it matters: Using generative models for structured judgments could push the emerging "decision model" niche toward cheaper, faster inference.
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.
