When what you need is not text but a quick "yes, no, or this one", models answer many times faster and almost for free.
OpenAI opened a public beta of the Decisions API: it takes text and images and returns a structured decision instead of text, namely the probability that a statement is true, a choice from given options with a confidence level, or a rating on a scale. According to OpenAI, it runs about 10 times faster than GPT-6 Luna through the Responses API; only gpt-6-luna is supported. It costs $0.10 per million input tokens, with output tokens and cache not billed; there is no caching in the beta. Users on the forum report skewed probabilities in multiple-choice questions. According to The Decoder, use cases include damage detection, routing of customer inquiries and document classification; general availability is promised soon.
