OpenAI opens Decisions API as decision-model rivalry continues
October 23 reports add no further facts beyond the Decisions API rollout and the commentary that Jev’s hype has faded.
OpenAI’s Decisions API is now open to all customers with lower latency, while a blog says Jev’s marketing claims have faded.
OpenAI made its Decisions API available to all customers on October 22, after announcing it on September 29. Product lead Nikunj Handa said the team reconfigured ChatGPT Luna rather than training a dedicated decision model, cutting typical latency from one to three seconds to about 100–180 milliseconds. Early users include Box, Datadog, Ramp, and Speak; Speak said action time fell from 1.4 seconds to 0.13 seconds. Public indexes still rank dedicated models, including TypeSafe’s latest Jev, above OpenAI. A Hacker News commentary argues Jev, marketed as a schema-constrained classifier trained with Reinforcement Learning for Calibrated Decisions, is matched by open-weight rivals and that its hype faded within weeks.
