OpenAI opens Decisions API at $0.10 per million input tokens, targets TypeSafe's Jev category

OpenAI made its Decisions API generally available on October 22, 2026, priced at $0.10 per million input tokens with no charges for output tokens, cache reads, or cache writes. The API competes directly with TypeSafe, whose Jev model pioneered the category of fast structured "decision" or "System One" models. Running on ChatGPT-Luna, the Decisions API returns typed outputs such as predicates, choices, and rubric scores, and can handle up to 400 questions per request. OpenAI claims it is up to 10 times faster than the standard Responses API, with latency around 150 milliseconds. Early customers include Box, Datadog, Ramp, and Speak. Since its beta on September 29, OpenAI added GPT-Live integration, prompt caching, and image and JSON input support. TypeSafe, founded by a former OpenAI researcher, reached a $7.6 billion valuation on Jev. OpenAI's API product lead noted that internal use cases prompted a sprint to ship a competing product. The pricing undercuts general-purpose LLMs for classification and routing, trading specialized training for speed to market.
