OpenAI makes its Jev competitor widely available as decision model competition heats up

OpenAI has made its Decisions API model widely available to all customers, entering the market for fast, cheap decision models pioneered by TypeSafe's Jev, which reconfigured ChatGPT Luna to cut inference times to 100-180 milliseconds. The public version adds new voice and visual modalities and geographically targeted inference resources, with customers like Box, Datadog, Ramp, and Speak using it to replace LLMs at higher throughput. TypeSafe's Jev remains the most widely-queried on OpenRouter, while public benchmarks tend to favor Liquid's D1 Ultra and Base Lab's Elephant-1.
